From eye exams to blood tests and surgery: how doctors use light to diagnose disease

<p><em><a href="https://theconversation.com/profiles/matthew-griffith-1539353">Matthew Griffith</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>You’re not feeling well. You’ve had a pounding headache all week, dizzy spells and have vomited up your past few meals.</p> <p>You visit your GP to get some answers and sit while they shine a light in your eyes, order a blood test and request some medical imaging.</p> <p>Everything your GP just did relies on light. These are just some of the optical technologies that have had an enormous impact in how we diagnose disease.</p> <h2>1. On-the-spot tests</h2> <p>Point-of-care diagnostics allow doctors to test patients on the spot and get answers in minutes, rather than sending samples to a lab for analysis.</p> <p>The “flashlight” your GP uses to view the inside of your eye (known as an <a href="https://medlineplus.gov/ency/article/003881.htm">ophthalmoscope</a>) is a great example. This allows doctors to detect abnormal blood flow in the eye, deformations of the cornea (the outermost clear layer of the eye), or swollen optical discs (a round section at the back of the eye where the nerve link to the brain begins). Swollen discs are a sign of elevated pressure inside your head (or in the worst case, a brain tumour) that could be <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/headache/increased-intracranial-pressure-icp-headache">causing your headaches</a>.</p> <p>The invention of <a href="https://openmedscience.com/lighting-the-way-in-healthcare-the-transformative-role-of-lasers-in-medicine/">lasers and LEDs</a> has enabled many other miniaturised technologies to be provided at the bedside or clinic rather than in the lab.</p> <p><a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">Pulse oximetry</a> is a famous example, where a clip attached to your finger reports how well your blood is oxygenated. It does this by <a href="https://www.howequipmentworks.com/pulse_oximeter/">measuring</a> the different responses of oxygenated and de-oxygenated blood to different colours of light.</p> <p>Pulse oximetry is used at hospitals (and <a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">sometimes at home</a>) to monitor your respiratory and heart health. In hospitals, it is also a valuable tool for detecting <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60107-X/fulltext">heart defects in babies</a>.</p> <h2>2. Looking at molecules</h2> <p>Now, back to that blood test. Analysing a small amount of your blood can diagnose <a href="https://theconversation.com/blood-tests-and-diagnosing-illness-what-can-blood-tell-us-about-whats-happening-in-our-body-80327">many different diseases</a>.</p> <p>A machine called an automated “full blood count analyser” tests for general markers of your health. This machine directs focused beams of light through blood samples held in small glass tubes. It counts the number of blood cells, determines their specific type, and reports the level of haemoglobin (the protein in red blood cells that distributes oxygen around your body). In minutes, this machine can provide a <a href="https://www.nuffieldhealth.com/article/inside-the-pathology-lab-what-happens-to-my-blood">snapshot</a> of your overall health.</p> <p>For more specific disease markers, blood serum is separated from the heavier cells by spinning in a rotating instrument called a centrifuge. The serum is then exposed to special chemical stains and enzyme assays that change colour depending on whether specific molecules, which may be the sign of a disease, are present.</p> <p>These colour changes can’t be detected with the naked eye. However, a light beam from an instrument called a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5476943/#R88">spectrometer</a> can detect tiny amounts of these substances in the blood and determine if the biomarkers for diseases are present, and at what levels.</p> <h2>3. Medical imaging</h2> <p>Let’s re-visit those medical images your GP ordered. The development of fibre-optic technology, made famous for transforming high-speed digital communications (such as the NBN), allows light to get inside the body. The result? High-resolution optical imaging.</p> <p>A common example is an <a href="https://www.medicalnewstoday.com/articles/153737#risks-and-side-effects">endoscope</a>, where fibres with a tiny camera on the end are inserted into the body’s natural openings (such as your mouth or anus) to examine your gut or respiratory tracts.</p> <p>Surgeons can insert the same technology through tiny cuts to view the inside of the body on a video screen during <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9553337/">laparoscopic surgery</a> (also known as keyhole surgery) to diagnose and treat disease.</p> <h2>How about the future?</h2> <p>Progress in nanotechnology and a better understanding of the interactions of light with our tissues are leading to new light-based tools to help diagnose disease. These include:</p> <ul> <li> <p><a href="https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201903441">nanomaterials</a> (materials on an extremely small scale, many thousands of times smaller than the width of a human hair). These are being used in next-generation sensors and new diagnostic tests</p> </li> <li> <p><a href="https://www.nature.com/articles/s41587-019-0045-y">wearable optical biosensors</a> the size of your fingernail can be included in devices such as watches, contact lenses or finger wraps. These devices allow non-invasive measurements of sweat, tears and saliva, in real time</p> </li> <li> <p>AI tools to analyse how blood serum scatters infrared light. This has allowed researchers to build a <a href="https://www.advancedsciencenews.com/powerful-diagnostic-approach-uses-light-to-detect-virtually-all-forms-of-cancer/">comprehensive database</a> of scatter patterns to detect <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/aisy.202300006">any cancer</a></p> </li> <li> <p>a type of non-invasive imaging called <a href="https://www.ncbi.nlm.nih.gov/books/NBK554044/">optical coherence tomography</a> for more detailed imaging of the eye, heart and skin</p> </li> <li> <p>fibre optic technology to deliver a tiny microscope into the body on the <a href="https://www.uwa.edu.au/projects/microscope-in-a-needle">tip of a needle</a>.</p> </li> </ul> <p>So the next time you’re at the GP and they perform (or order) some tests, chances are that at least one of those tests depend on light to help diagnose disease.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231379/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/matthew-griffith-1539353"><em>Matthew Griffith</em></a><em>, Associate Professor and ARC Future Fellow and Director, UniSA Microscopy and Microanalysis Facilities, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Rare coin hidden for decades to fetch eye-watering sum

<p>Three sisters from the US who inherited a dime coin kept it in a bank vault for more than 40 years, and while they know it had some value, they didn't know just how much until a few years ago. </p> <p>The rare coin, struck by the US Mint in San Francisco in 1975, could be worth more than $US500,000 ($748,000), according to Ian Russell, president of GreatCollections, the auction house selling the coin. </p> <p>What makes the coin depicting President Franklin D. Roosevelt so valuable is that it is just one of two coins missing the "S" mint mark for San Francisco. </p> <p>The other dime sold for $US682,000 (over $1 million) at a 2019 auction and then again months later to a private collector. </p> <p>While avid coin collectors have known about the existence of these two extraordinarily rare coins, their whereabouts had remained a mystery since the late 1970s. </p> <p>“They were hidden for decades,” Russell said.</p> <p>“Most major collectors and dealers have never seen one.”</p> <p>The three sisters from Ohio, who want to remain anonymous, inherited one of the two dimes after the recent death of their of their brother, Russell said. </p> <p>They told Russell that their brother and mother bought the first error coin discovered in 1978 for $27,225, which would amount to roughly $135,000 today.</p> <p>Their parents, who ran a dairy farm, saw the coin as a financial safety net, and it was only until last year that one of the sisters saw the coin first-hand. </p> <p>Russell also said that their brother had reached out to him about seven years ago and told him about the coin, but he too kept it a secret. </p> <p>When Russell told one of the sisters about the potential value of the coin, she told him: “is that really possible?”. </p> <p>The coin, known as the “1975 ‘no S’ proof dime,” will be displayed at a coin show beginning on Wednesday in Tampa, Florida, and before <a href="https://www.greatcollections.com/Coin/1655587" target="_blank" rel="noopener">the auction</a> closes late next month, Russell said.</p> <p>The current highest bidder has offered $US250,000 ($374,000).</p> <p><em>Images: Great Collections/ Professional Coin Grading Services</em></p>

Doctor shares her holy grail tips for overcoming eye sensitivity

<p>As the chill of winter sets in, many people find that their eyes become more sensitive and prone to dryness. This can be particularly challenging for those who already suffer from dry eye syndrome. </p> <p>Dr. Jacqueline Beltz is a leading Australian Ophthalmologist and the founder of <a href="https://www.okkiyo.com" target="_blank" rel="noopener">OKKIYO</a>, a beauty brand that makes PRIORITEYES mascara for people with sensitive eyes.</p> <p>Dr Beltz has shared her insights into dry eye syndrome and how winter can exacerbate symptoms, also sharing her top tips for managing eye sensitivity during the colder months.</p> <p><strong>Understanding Dry Eye Syndrome</strong></p> <p>The surface of the eye is covered by a delicate layer of tears, essential for comfort, vision, protection, and nutrition. The tear film comprises two main layers: an outer lipid (oily) layer and an inner aqueous (watery) layer. The lipid layer, produced by oil glands in the eyelids, prevents tears from evaporating too quickly, while the aqueous layer, consisting of water, electrolytes, and proteins, spreads tears evenly across the eye and helps them adhere to the surface.</p> <p>When the balance of tear production, evaporation, absorption, and drainage is disrupted, it can lead to dry eye syndrome. Symptoms may include redness, irritation, a gritty sensation, tired eyes, itching, excessive watering, and fluctuating vision. In severe cases, dry eye can be painful and significantly impact daily life.</p> <p><strong>How common is dry eye syndrome?</strong></p> <p>Dry eye syndrome is a widespread issue, particularly among older adults. According to the Blue Mountains Eye Study, 57% of adults over the age of 50 experience some degree of dry eye. This condition is notably more prevalent in women, with higher rates observed compared to their male counterparts. The increased prevalence in women is often attributed to hormonal changes, particularly during and after menopause. </p> <p>A more recent study, Optometry Australia’s 2022 Vision index found that over 85% of Australians are estimated to have experienced dry eyes at some point in their lives. Of those affected, 55% say they only developed the condition following the beginning of the pandemic in 2020. They reported that almost 1 in 5 (18%) of people experience dry eye symptoms frequently. </p> <p>These statistics highlight the importance of understanding and managing dry eye, especially as we age.</p> <p><strong>DEWS II Study and Treatment Approaches</strong></p> <p>The DEWS II (Dry Eye Workshop II) study provides a comprehensive framework for understanding and treating dry eye syndrome. According to the study, dry eye is a multifactorial disease characterised by a loss of homeostasis (or balance) in the tear film, accompanied by eye symptoms. Factors such as tear film instability, hyperosmolarity (increased saltiness), inflammation, and neurosensory (altered feelings or sensations) abnormalities play significant roles.</p> <p>There are two primary types of dry eye: aqueous deficient and evaporative. Most individuals have a combination of both. Aqueous deficient dry eye occurs when there is insufficient production of the watery layer of tears, often due to aging, hormonal changes, or certain medications. Evaporative dry eye is typically caused by environmental factors or conditions affecting the lipid layer, such as meibomian gland dysfunction (MGD).</p> <p><strong>Winter's Impact on Dry Eyes</strong></p> <p>Winter poses unique challenges for dry eye sufferers. Cold, dry air, indoor heating, and wind can all exacerbate symptoms. Here's how to combat these winter-specific issues:</p> <p><em><strong>1. Humidify Your Environment</strong></em></p> <p>Indoor heating reduces humidity levels, leading to increased tear evaporation. Consider using a humidifier to maintain moisture in the air, especially in bedrooms and living spaces. This helps keep your eyes hydrated.</p> <p><em><strong>2. Protect Your Eyes Outdoors</strong></em></p> <p>Cold winds can strip away the tear film. When outside, wear wraparound sunglasses to shield your eyes from the elements. This not only protects your eyes from the wind but also from UV rays, which can be strong even in winter.</p> <p><em><strong>3. Stay Hydrated</strong></em></p> <p>Dehydration can worsen dry eye symptoms. Drink plenty of water throughout the day to maintain overall hydration, which supports healthy tear production.</p> <p><em><strong>4. Optimise Your Diet</strong></em></p> <p>Certain foods can promote eye health. Omega-3 fatty acids, found in fish like salmon and flaxseeds, have anti-inflammatory properties that can help manage dry eye symptoms. Incorporate these into your diet for added benefits.</p> <p><em><strong>5. Use a Warm Compress</strong></em></p> <p>A warm compress can help improve the function of the meibomian glands, which produce the oily layer of the tear film. This is particularly helpful for those with meibomian gland dysfunction, or MGD. Gently apply a warm, damp cloth to your closed eyelids for 10-15 minutes, followed by a gentle massage of the eyelids to encourage oil secretion. It is important to avoid rubbing or compressing the eyeballs.</p> <p><em><strong>6. Use Over-the-Counter Lubricant Eye Drops</strong></em></p> <p>Artificial tears can provide temporary relief by supplementing the natural tear film. Choose preservative-free options to avoid further irritation, and use them frequently.</p> <p><em><strong>7. Remember to have regular eye checks</strong></em></p> <p>In Australia, Optometrists provide our primary eye health check ups. Dr Beltz recommends adults over the age of 40 see their optometrist once a year, but if you’re struggling with symptoms of dry eye in winter, an extra check up might help and your optometrist will be able to help you to come up with an individualised treatment plan.</p> <p><em><strong>8. Invest in Quality Eye Products</strong></em></p> <p>For those who wear makeup, using products designed for sensitive eyes is crucial. <a href="https://www.okkiyo.com/products/protect-and-preserve-mascara" target="_blank" rel="noopener">PRIORITEYES</a> mascara by OKKIYO has been specifically formulated to be gentle on sensitive eyes, avoiding common irritants while providing excellent performance.</p> <p><strong>Managing Dry Eye in Winter: A Recap</strong></p> <p>Winter can be tough on our eyes, but with the right strategies, you can manage dry eye symptoms effectively. Maintain a humid environment, protect your eyes from cold winds, stay hydrated, and incorporate eye-healthy foods into your diet. Regularly use warm compresses and opt for gentle, high-quality eye products like PRIORITEYES mascara. </p> <p>Dry eye syndrome may be a common condition, but it doesn't have to dominate your life, especially during the harsh winter months. With these tips, you can keep your eyes comfortable and healthy all season long. For personalised advice and treatment, always consult with your eye care professional.</p> <p>Stay warm, stay hydrated and take care of your eyes this winter!</p> <p><em>Image credits: Shutterstock </em></p>

Eye infections might seem like a minor complaint – but in some cases they can cause blindness and even death

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>When you think of eye infections, what comes to mind? Puffy, swollen bruised feeling eyelids that get glued together with gunk overnight? That feeling of having grit in your eye that can’t be cleaned away? Eye infections may seem like a relatively minor – if unsightly and inconvenient – complaint, but they can also be far more serious.</p> <p>Take the deadly outbreak of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5022785/">antibiotic resistant</a> bacteria <a href="https://www.cff.org/managing-cf/burkholderia-cepacia-complex-b-cepacia"><em>Burkholderia cepacia</em></a> in 2023-24, for example.</p> <p>Between January 2023 and February 2024, contaminated brands of lubricating eye gel were linked to the infection of at least 52 patients. <a href="https://www.independent.co.uk/news/health/contaminated-eye-gel-outbreak-death-b2523446.html">One person died</a> and at least 25 others suffered serious infections.</p> <p>The outbreak has now subsided and products are <a href="https://www.gov.uk/drug-device-alerts/specific-brands-of-carbomer-eye-gel-recall-of-aacarb-eye-gel-aacomer-eye-gel-and-puroptics-eye-gel-potential-risk-of-infection-dsi-slash-2023-slash-11#update-2-april-2024">back on the shelves</a> but it isn’t the first time that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8335909/">medicinal products</a> have led to outbreaks of <em>B cepacia</em>.</p> <p>The bacterium is an opportunistic pathogen known to pose a significant risk to people with cystic fibrosis, chronic lung conditions and weakened immune systems. The infection likely progresses from the mucous membranes of the eyelids to the lungs where it leads to pneumonia and septicaemia causing <a href="https://erj.ersjournals.com/content/17/2/295">death in days</a>.</p> <p>But it’s not just <em>B cepacia</em> that can threaten our health. Something as simple as rubbing our eyes can introduce pathogens leading to infection, blindness and, in the worst case, death.</p> <p>Bacteria account for up to <a href="https://pubmed.ncbi.nlm.nih.gov/16148850/">70% of eye infections</a> and globally <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9032492/">over 6 million people</a> have blindness or moderate visual impairment from ocular infection.

It converts light energy to chemical and then electrical energy, which is transmitted to the brain and converted to a picture. The eye uses about <a href="https://www.ncbi.nlm.nih.gov/books/NBK11556/">6 million cones and 120 million rods</a> which detect colour and light.</p> <p>Eye cells have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8775779/">no ability to regenerate</a> so, once damaged or injured, cannot be repaired or replaced. The body tries its best to preserve the eyes by encasing them in a <a href="https://www.ncbi.nlm.nih.gov/books/NBK531490/">bony protective frame</a> and <a href="https://www.ncbi.nlm.nih.gov/books/NBK482428/">limiting exposure</a> having eyelids to defend against the environmental damage and ensure the eyes are kept lubricated.</p> <p>Despite our bodies’ best efforts to shield the eyes from harm, there are a number of common eye infections that can result from introducing potential pathogens into the eyes.</p> <h2>Conjunctivitis</h2> <p>The outer-most layer of the eye, the sclera, bears the brunt of exposure and to help protect it, it is lined by a thin moist membrane called the <a href="https://my.clevelandclinic.org/health/body/24329-conjunctiva">conjunctiva</a>.</p> <figure><iframe src="https://www.youtube.com/embed/RZ4danuJwd0?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>The conjunctiva is <a href="https://innovations.bmj.com/content/9/4/253">highly vascularised</a>, which means it has lots of blood vessels. When microbes enter the eye, it is this layer that mounts an immune response causing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8328962/">blood vessels to dilate</a> in the conjunctiva. This results in <a href="https://www.cdc.gov/conjunctivitis/about/symptoms.html">“pink eye”</a>, a common form of conjunctivitis. Conjunctivitis can be caused by bacteria, allergens or viruses and typically heals by itself.</p> <h2>Blepharitis</h2> <p>Blepharitis is an inflammation of the eyelid and usually affects both sides. It can cause itchy eyes and dandruff-like flakes. It’s most commonly caused by <a href="https://www.tandfonline.com/doi/pdf/10.3109/09273948.2013.870214"><em>Staphylococcus</em> bacteria</a>, or the <a href="https://cks.nice.org.uk/topics/blepharitis/background-information/causes/">dysfunction of the glands</a> of the eyelids. It can be treated by <a href="https://www.nhs.uk/conditions/blepharitis/">cleaning the eyes</a> regularly.</p> <h2>Stye</h2> <p>A stye (also called <a href="https://www.college-optometrists.org/clinical-guidance/clinical-management-guidelines/hordeolum">hordeolum</a>) is a painful infection of the upper or lower eyelid. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5370090/">Internal styes</a> are caused by infection of an oil-producing gland inside the eyelid, whereas <a href="https://pubmed.ncbi.nlm.nih.gov/28723014/">external styes</a> develop at the base of the eyelash because of an infection of the hair follicle. Both are caused by bacteria, typically <a href="https://jamanetwork.com/journals/jamaophthalmology/fullarticle/1874715">the <em>S aureus</em> form of the <em>Staphylococcus</em> species</a>.</p> <figure><iframe src="https://www.youtube.com/embed/INKrGOdy824?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Styes can be treated by holding a clean flannel soaked in warm water against the affected eye for five to ten minutes, three or four times a day. Do not try to burst styes – this could spread the infection.</p> <h2>Keratitis</h2> <p>Keratitis is the inflammation of the cornea, the transparent part of the eye that light passes through. The cornea is part of the eye’s main barrier against dirt, germs, and disease. Severe keratitis can cause ulcers, damage to the eye and even blindness.</p> <p>The most common type is bacterial keratitis; however, it can also be caused by <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7998329/">amoeba</a>, which can migrate to other parts of the body – including the brain – and cause infection and <a href="https://theconversation.com/nasal-rinsing-why-flushing-the-nasal-passages-with-tap-water-to-tackle-hay-fever-could-be-fatal-225811">even death</a>.</p> <p>Noninfectious keratitis is most commonly caused by wearing contact lenses for too long, especially while sleeping. This can cause scratches, dryness and soreness of the cornea, which leads to inflammation.</p> <h2>Uveitis</h2> <p><a href="https://www.nhs.uk/conditions/uveitis/">Uveitis</a> is inflammation of the middle layer of the eye. Although relatively rare, it is a serious condition and usually results from viral infections such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8501150/">herpes simplex</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/29023181/">herpes zoster</a> or <a href="https://link.springer.com/chapter/10.1007/978-3-319-09126-6_40">trauma</a>. Depending on where the inflammation is in the eye, the symptoms can be anything from redness, pain and floaters to blurred vision and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1772296/">partial blindness</a>.</p> <h2>Exogenous endophthalmitis</h2> <p>This is a rare but serious infection caused by eye surgery complications, penetrating ocular trauma (being stabbed in the eye with a sharp object) or foreign bodies in the eye. Foreign bodies can be anything from dirt and dust to small projectiles such as shards of metal from drilling, explosives or soil from farm machinery and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7286045/">many other sources</a>.</p> <h2>Dacryocystitis</h2> <p>Dacryocystitis is the inflammation of the nasolacrimal sac, which drains tears away from the eye into the nose. This condition can be <a href="https://pubmed.ncbi.nlm.nih.gov/8443113/">acute</a>, <a href="https://www.nature.com/articles/6700662">chronic</a> or <a href="https://www.jebmh.com/articles/a-study-of-congenital-dacryocystitis.pdf.pdf">acquired at birth</a>. Most cases are caused by <a href="https://bmcophthalmol.biomedcentral.com/articles/10.1186/s12886-020-01792-4"><em>Streptococcus pneumoniae</em> and <em>Staphylococcus aureus</em></a> bacteria.</p> <p>The condition mainly affects newborns and those over 40. Seventy-five per cent of cases are women and it’s most commonly found in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6039673/">white adults</a>. It can lead to the stagnation of tears, creating a breeding ground for microbes.</p> <h2>Careful with contacts</h2> <p>Proper eye hygiene reduces the risk of all these conditions – and this is even more important for contact lens wearers.</p> <figure><iframe src="https://www.youtube.com/embed/uENHAntJOIA?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Appropriate hygienic cleaning of lenses is paramount. <a href="https://pubmed.ncbi.nlm.nih.gov/30789440/">Non-sterile water</a>, <a href="https://www.aao.org/eye-health/glasses-contacts/contact-lens-care">spit</a> and other fluids can transfer <a href="https://www.science.org/content/article/bacteria-living-your-contact-lens-solution">potentially dangerous</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3482476/">microbes</a> into the eye – a warm, moist environment that makes an ideal breeding ground for bacteria – leading to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9542356/">localised infection</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3972779/">blindness</a> or progress to a more serious <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9835757/">systemic infection or death</a>.</p> <p>Any persistent and painful redness or swelling of eyes should be checked by a registered health professional.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/227252/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Could my glasses be making my eyesight worse?

<p><em><a href="https://theconversation.com/profiles/james-armitage-399647">James Armitage</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/nick-hockley-1517162">Nick Hockley</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>So, you got your eyesight tested and found out you need your first pair of glasses. Or you found out you need a stronger pair than the ones you have. You put them on and everything looks crystal clear. But after a few weeks things look blurrier without them than they did before your eye test. What’s going on?</p> <p>Some people start to wear spectacles for the first time and perceive their vision is “bad” when they take their glasses off. They incorrectly interpret this as the glasses making their vision worse. Fear of this might make them <a href="https://www.bbc.com/future/article/20140513-do-glasses-weaken-your-eyesight#:%7E:text=A%20study%20from,they%20are%20right%3F">less likely to wear their glasses</a>.</p> <p>But what they are noticing is how much better the world appears through the glasses. They become <a href="https://www.tandfonline.com/doi/full/10.1080/2576117X.2022.2033588">less tolerant</a> of a blurry world when they remove them.</p> <p>Here are some other things you might notice about eyesight and wearing glasses.</p> <h2>Lazy eyes?</h2> <p>Some people sense an increasing reliance on glasses and wonder if their eyes have become “lazy”.</p> <p>Our eyes work in much the same way as an auto-focus camera. A flexible lens inside each eye is controlled by muscles that let us <a href="https://www.aao.org/museum-eye-openers/how-does-eye-focus">focus on objects</a> in the distance (such as a footy scoreboard) by relaxing the muscle to flatten the lens. When the muscle contracts it makes the lens steeper and more powerful to see things that are much closer to us (such as a text message).</p> <p>From the age of about 40, the lens in our eye <a href="https://theconversation.com/why-we-lose-our-hearing-and-vision-as-we-age-67930">progressively hardens</a> and loses its ability to change shape. Gradually, we lose our capacity to focus on near objects. This is called “<a href="https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/presbyopia">presbyopia</a>” and at the moment there are no treatments for this lens hardening.</p> <p>Optometrists correct this with prescription glasses that take the load of your natural lens. The lenses allow you to see those up-close images clearly by providing extra refractive power.</p> <p>Once we are used to seeing clearly, our tolerance for blurry vision will be lower and we will reach for the glasses to see well again.</p> <h2>The wrong glasses?</h2> <p>Wearing old glasses, the wrong prescription (or even someone else’s glasses) won’t allow you to see as well as possible for day-to-day tasks. It could also cause <a href="https://headaches.org/readers-mail-glasses-causing-headache/">eyestrain and headaches</a>.</p> <p>Incorrectly prescribed or dispensed prescription glasses can lead to vision impairment in children <a href="https://iovs.arvojournals.org/article.aspx?articleid=2126392">as their visual system is still in development</a>.</p> <p>But it is more common for kids to develop long-term vision problems as a result of <a href="https://www.cera.org.au/wp-content/uploads/2021/08/Healthy-Young-Eyes-Guide-ACC.pdf">not wearing glasses when they need them</a>.</p> <p>By the time children are about 10–12 years of age, wearing incorrect spectacles is less likely to cause their eyes to become lazy or damage vision in the long term, but it is likely to result in <a href="https://www.cera.org.au/wp-content/uploads/2021/08/Healthy-Young-Eyes-Guide-ACC.pdf">blurry or uncomfortable vision</a> during daily wear.</p> <p><a href="https://goodvisionforlife.com.au/">Registered optometrists in Australia</a> are trained to assess refractive error (whether the eye focuses light into the retina) as well as the different aspects of ocular function (including how the eyes work together, change focus, move around to see objects). All of these help us see clearly and comfortably.</p> <h2>What about dirty glasses?</h2> <p>Dirty or scratched glasses can give you the impression your vision is worse than it actually is. Just like a window, the dirtier your glasses are, the more difficult it is to see clearly through them. <a href="https://www.optometry.org.au/wp-content/uploads/GVFL/Brochure_PDFs/Care-for-Glasses-2018-A4-single-page-final.pdf">Cleaning glasses regularly</a> with a microfibre lens cloth will help.</p> <p>While dirty glasses are not commonly associated with eye infections, some research suggests dirty glasses can <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0207238">harbour bacteria</a> with the remote but theoretical <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6628431/#:%7E:text=59%2C60%5D.-,S.,39%2C40%2C41%5D.">potential to cause eye infection</a>.</p> <p>To ensure best possible vision, people who wear prescription glasses every day should clean their lenses at least every morning and twice a day where required. Cleaning frames with alcohol wipes can <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0207238">reduce bacterial contamination by 96%</a> – but care should be taken as alcohol can damage some frames, depending on what they are made of.</p> <h2>When should I get my eyes checked?</h2> <p><a href="https://goodvisionforlife.com.au/faqs/">Regular eye exams</a>, starting just before school age, are important for ocular health. Most prescriptions for corrective glasses <a href="https://www.ahpra.gov.au/documents/default.aspx?record=WD16%2F20156&dbid=AP&chksum=676U2aH1QM4XJ6ICVAVaKg%3D%3D">expire within two years</a> and contact lens prescriptions often expire after a year. So you’ll need an eye check for a new pair every year or so.</p> <p>Kids with ocular conditions such as progressive myopia (short-sightedness), strabismus (poor eye alignment), or amblyopia (reduced vision in one eye) will need checks at least every year, but likely more often. Likewise, people over 65 or who have known eye conditions, such as <a href="https://goodvisionforlife.com.au/vision-problems/glaucoma/">glaucoma</a>, will be recommended more frequent checks.</p> <p>An <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6706420/">online prescription estimator</a> is no substitute for a full eye examination. If you have a valid prescription then you can order glasses online, but you miss out on the ability to check the fit of the frame or to have them adjusted properly. This is particularly important for multifocal lenses where even a millimetre or two of misalignment can cause uncomfortable or blurry vision.</p> <p>Conditions such as <a href="https://www.cdc.gov/diabetes/managing/diabetes-vision-loss.html#:%7E:text=Diabetic%20retinopathy%20is%20caused%20when,vision%20or%20stopping%20blood%20flow.">diabetes</a> or <a href="https://www.ncbi.nlm.nih.gov/books/NBK525980/">high blood pressure</a>, can affect the eyes so regular eye checks can also help flag broader health issues. The vast majority of eye conditions can be treated if caught early, highlighting the importance of regular preventative care.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225169/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/james-armitage-399647">James Armitage</a>, Associate Professor in Vision Science, Optometry Course Director, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/nick-hockley-1517162">Nick Hockley</a>, Lecturer in Optometric Clinical Skills, Director Deakin Collaborative Eye Care Clinic, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Top tips for happy and healthy eyes this Autumn

<p dir="ltr">As the season changes, so do our healthcare needs as many people struggle with irritating allergies. </p> <p dir="ltr">With cooler temperatures, dry air and an increase in pollen often being synonymous with autumn and spring, for many people, leaving the house means having irritated eyes. </p> <p dir="ltr">Luckily, leading Ophthalmologist, Dr. Jacqueline Beltz has shared her essential tips for eye care during autumn with OverSixty, giving you the opportunity to enjoy the change of seasons without jeopardising your vision. </p> <p dir="ltr"><strong>1. Keep your sunglasses handy</strong></p> <p dir="ltr">While the sun is usually not as intense in autumn as it is during summer, Dr Beltz says that using sunglasses can benefit your eyes in many ways. </p> <p dir="ltr">“ Not only do they shield your eyes from harmful UV rays, but they also guard against wind and debris,” she said. </p> <p dir="ltr"><strong>2. Increase your lubricant eye drops</strong></p> <p dir="ltr">Dr Beltz said, “The drop in temperature and the dryer air can contribute to discomfort and dryness in your eyes, so consider increasing the use of lubricant eye drops to keep your eyes moist and comfortable.”</p> <p dir="ltr">By keeping up your eye drops in autumn, you can prevent further damage to your eyes in the long run. </p> <p dir="ltr"><strong>3. Clean your eyelashes daily</strong></p> <p dir="ltr">According to Dr Beltz, keeping up with good health and hygiene along the eyelid margins is essential, especially during the autumn months. </p> <p dir="ltr">“Cleanse your lashes daily and use a warm compress to optimise the quality of your tear film. This helps in preventing irritation and supports overall eye health.”</p> <p dir="ltr"><strong>4. Consider a humidifier</strong></p> <p dir="ltr">To ensure a more comfortable environment for your eyes, Dr Beltz recommends adding moisture to the air can help alleviate dry eyes.</p> <p dir="ltr">She said, “Combat the dry indoor air by using a humidifier in your room, especially while you sleep.”</p> <p dir="ltr"><strong>5. Be proactive with allergies</strong></p> <p dir="ltr">If you are prone to allergies, Dr Beltz said it's best to always be prepared ahead of time. </p> <p dir="ltr">“Autumn allergies are a reality, with triggers like pollen, mould, and dust prevalent during this season,” she said. </p> <p dir="ltr">“If you experience red, itchy, or swollen eyes, consider antihistamine eye drops. Keep your hands clean and avoid rubbing your eyes.”</p> <p dir="ltr"><strong>6. Revitalise your eye makeup</strong></p> <p dir="ltr">While replacing your eye makeup is important all year around, the addition of allergens makes it even more important to Change mascara and non-cleanable products like liquid eyeliner at least every three months. </p> <p dir="ltr">“Especially if you have sensitive eyes, makeup products can harbour bacteria, leading to increased eye irritation.”</p> <p dir="ltr">“Refreshing your eye makeup products to options that are designed to be better suited for dry eyes or eye sensitivity.”</p> <p dir="ltr">If you are <a href="https://oversixty.com.au/lifestyle/beauty-style/embracing-the-art-of-beauty-without-compromise">prone to sensitive eyes</a>, consider trying the OKKIYO <a href="https://www.okkiyo.com/products/protect-and-preserve-mascara#xd_co_f=NzdiNzdlNTctNTA1MS00NTBkLWE1MGEtNjRkMGE2OTI1N2Vj~">Prioriteyes Mascara</a>, which was developed by Dr Beltz to prioritise both style and eye health.</p> <p dir="ltr">While these tips for eye health can seem simple and seemingly unimportant, Dr Beltz assures that by following these tips, you will make a world of difference for your eye health overall. </p> <p dir="ltr">She said, “Implementing these simple tips can make a significant difference in keeping your eyes comfortable and vibrant throughout the season.”</p> <p dir="ltr"><em>Image credits: Getty Images </em></p>

Eye-watering price tag for "remarkable" first class Titanic menu

<p>A first class dinner menu from the Titanic has been found and sold at an auction in England for £84,000 (around $162,000 AUD) on November 11. </p> <p>The water-stained menu was dated April 11, 1912 just three days before the ship hit an iceberg, ultimately meeting it's ill-fated end causing over 1500 deaths. </p> <p>Wealthy passengers at the time were spoiled with choice, with oysters, salmon, beef, squab (baby pigeon), spring lamb among other dishes on the menu, and that's not including dessert. </p> <p>Auctioneers Henry Aldridge & Son said it was unclear how the menu made it off the ship intact, but the slight water damage suggests that it was recovered from the body of a victim. </p> <p>The rare artefact, which is over 111 years old belonged to amateur historian Len Stephenson, from Nova Scotia, Canada, who passed away in 2017. </p> <p>No one knew he had it, including his family, who only discovered it after going through his belongings following his death. </p> <p>“About six months ago his daughter and his son-in-law, Allen, felt the time was right to go through his belongings,” auctioneer Andrew Aldridge said. </p> <p>“As they did they found this menu in an old photo album.</p> <p>“Len was a very well thought-of historian in Nova Scotia which has strong connections with the Titanic. The body recovery ships were from Nova Scotia and so all the victims were taken back there.</p> <p>“Sadly, Len has taken the secret of how he acquired this menu to the grave with him.”</p> <p>Stephenson worked at a post office and would talk to people, collect old pictures and write letters for them, which might be how he got the rare artefact. </p> <p>According to the auctioneer, no other first class dinner menus dated April 11, 1912 have been recovered from the titanic making this “a remarkable survivor from the most famous Ocean liner of all time”.</p> <p>“There are a handful of April 14 menus in existence but you just don’t see menus from April 11. Most of them would have gone down with the ship,” Aldridge said. </p> <p>“Whereas with April 14 menus, passengers would have still had them in their coat and jacket pockets from earlier on that fateful night and still had them when they were taken off the ship," he added. </p> <p>A few other items recovered from the Titanic were also sold, including a Swiss-made pocket watch recovered from passenger Sinai Kantor which fetched £97,000 (around $187,000 AUD). </p> <p>A tartan-patterned deck blanket, which was likely used during the rescue operation also sold for £96,000 (around $185,000). </p> <p><em>Images: Henry Aldridge & Son of Devizes, Wiltshire</em></p>

Do blue-light glasses really work? Can they reduce eye strain or help me sleep?

So, is the extra expense worth it?</p> <h2>Blue light is all around us</h2> <p>Outdoors, sunlight is the main source of blue light. Indoors, light sources – such as light-emitting diodes (LEDs) and the screens of digital devices – emit varying degrees of blue light.</p> <p>The amount of blue light emitted from artificial light sources is much lower than from the Sun.

We identified 17 eligible trials from six countries, involving a total of 619 adults.</p> <h2>Do they reduce eye strain?</h2> <p>We found no benefit of using blue light-filtering lenses, over standard (clear) lenses, to reduce eye strain with computer use.</p> <p>This conclusion was based on consistent findings from three studies that evaluated effects on eye strain over time periods ranging from two hours to five days.</p> <h2>Do they help you sleep?</h2> <p>Possible effects on sleep were uncertain. Six studies evaluated whether wearing blue-light filtering lenses before bedtime could improve sleep quality, and the findings were mixed.</p> <p>These studies involved people with a diverse range of medical conditions, including insomnia and bipolar disorder. Healthy adults were not included in the studies. So we do not yet know whether these lenses affect sleep quality in the general population.</p> <h2>Do they boost your eye health?</h2> <p>We did not find any clinical evidence to support using blue-light filtering lenses to protect the macula (the region of the retina that controls high-detailed, central vision).</p> <p>None of the studies evaluated this.</p> <h2>Could they do harm? How about causing headaches?</h2> <p>We could not draw clear conclusions on whether there might be harms from wearing blue light-filtering lenses, compared with standard (non blue-light filtering) lenses.</p> <p>Some studies described how study participants had headaches, lowered mood and discomfort from wearing the glasses. However, people using glasses with standard lenses reported similar effects.</p> <h2>What about other benefits or harms?</h2> <p>There are some important general considerations when interpreting our findings.</p> <p>First, most of the studies were for a relatively short period of time, which limited our ability to consider longer-term effects on vision, sleep quality and eye health.</p> <p>Second, the review evaluated effects in adults. We don’t yet know if the effects are different for children.</p> <p>Finally, we could not draw conclusions about the possible effects of blue light-filtering lenses on many vision and eye health measures, including colour vision, as the studies did not evaluate these.</p> <h2>In a nutshell</h2> <p>Overall, based on relatively limited published clinical data, our review does not support using blue-light filtering lenses to reduce eye strain with digital device use. It is unclear whether these lenses affect vision quality or sleep, and no conclusions can be drawn about any potential effects on the health of the retina.</p> <p>High-quality research is needed to answer these questions, as well as whether the effectiveness and safety of these lenses varies in people of different ages and health status.</p> <p>If you have eye strain, or other eye or vision concerns, discuss this with your optometrist. They can perform a thorough examination of your eye health and vision, and discuss any relevant treatment options.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/213145/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/laura-downie-1469379"><em>Laura Downie</em></a><em>, Associate Professor in Optometry and Vision Sciences, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Princess Diana's dresses fetch an eye-watering sum at auction

<p>Three dresses worn by Princess Diana have sold for $2.5 million (AUD) at an auction in Beverly Hills, California. </p> <p>The gowns were sold in a <em>Legends: Hollywood And Royalty</em> sale, by Julien's Auctions and featured over 1,400 items to celebrate 100 years of Warner Bros. </p> <p>All three dresses sold for six-figures, with one selling for almost triple it's estimated price. </p> <p>Martin Nolan, the executive director, said the record-breaking sale of Diana's dresses "exceeded all expectations".</p> <p>Princess Diana's black and jade gown was the most expensive item, selling for $895,580. </p> <p>The dress was made by Catherine Walker - her personal designer for over 16 years - which she wore to a gala event in Toronto, Canada, in October 1991. </p> <p>The second most expensive dress sold was a red silk dress made by Bruce Oldfield, which she wore to the premiere of<em> Hot Shots</em> at the Odeon Leicester Square the following month. </p> <p>The Oldfield dress fetched a stunning $895,547 - which was almost triple it's estimated $312,000 price tag.</p> <p>The final dress was a custom-made black velvet and ivory gown Diana wore to a private function, which was also designed by Walker, and fetched $796,070. </p> <p>The original price of the velvet and ivory gown was estimated to be around $93,000 - $125,000. </p> <p>The three dresses have not been seen in public for over 30 years, according to the auction house.</p> <p>They were originally bought by American businesswoman Ellen Petho, who bought five of Princess Diana's dresses for $234,000 at an auction in New York. </p> <p>Petho, who passed away in January aged 82, ended up only keeping three of the dresses, which her husband has now sold to help raise money for a scholarship fund for mature art and design students in memory of his wife.</p> <p>Petho's daughter Karrie, told the <em>Mail</em>: "Our mother read the inscription inside [the auction catalogue] about Prince William telling his mother that the dresses should not sit in her closet, that they should be out in the world and doing good. I think that's what inspired her."</p> <p><em>Image: Brian Lawless/PA Images via Getty Images</em></p>

"I can’t a fjord it": Inside one of the world’s most extreme restaurants

<p>One of the world's most extreme restaurants has gone viral and not only for its unique location and shape, but also its exclusive dining experience that's eerily similar to 2022 horror film <em>The Menu</em>.</p> <p>Restaurant Iris is located inside a giant silvery orb in Hardangerfjord, the second largest Fjord in Norway.</p> <p>The four-storey structure, called the Salmon Eye is inspired by - you guessed it - the shape of a fish eye, and it is quite a sight to behold. </p> <p>The Salmon Eye is covered in 9,000 steel plates to emulate fish scales, weighing a whopping 1,256 tonnes and an impressive diameter of 25 metres, with one sub-surface floor that boasts a panoramic view of the Fjord. </p> <p>The restaurant itself can only be accessed by an electric boat off the shore of Rosendal, as guests are treated to "an exclusive expedition dining-journey" which offers an 18-course meal and panoramic views. </p> <p>The 24-seat restaurant is run by Head Chef Anika Madsen, and prior to having their main meal, guests are taken to the chef's boathouse on the nearby island of Snilstveitoy, for a "welcoming snack". </p> <p>The menu is designed to showcase "the most local ingredients possible", which reflects Madsen's "commitment to sustainability" and her "<span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">passion for discovering new ingredients from the ocean". </span></p> <p>Mari Eriksmoen posted the viral video on TikTok which has racked up over eight million views. </p> <p>"This spectacular just opened in the middle of the Hardangerfjord in Norway," she started in the clip with a shot of the structure floating in the middle of the fjord. </p> <p>She described the experience of walking into the restaurant "like entering a spaceship," and was mesmerised by the "insane views". </p> <p>Once the evening kicks off, guests indulge in a multi-sensory experience where they were instructed to pick a "cracker" hanging from the ceiling after watching a "short movie about food waste". </p> <p>Another TikTok user compared it to the <span style="background-color: #ffffff; font-family: graphik, Arial, sans-serif; font-size: 16px; letter-spacing: -0.16px;">extraterrestrial spacecraft </span><span style="background-color: #ffffff; font-family: graphik, Arial, sans-serif; font-size: 16px; letter-spacing: -0.16px;">from the 2016 sci-fi film <em>Arrival</em>.</span></p> <p>However many other users compared the dining experience to 2022 horror film <em>The Menu</em>, where a group of guests eat at an exclusive restaurant on a remote island and face dire consequences. </p> <p>"Did we learn nothing from The Menu?" commented one user with the crying face emoji. </p> <p>"I know how this movie ends," wrote another user. </p> <p>"I can’t a fjord it," joked a third. </p> <p>The dining experience aims to "blend gastronomy and activism on a global scale" as they hope to raise awareness on the the challenges and threats to the global food system. </p> <p>"The menu at Iris reads like a story, " a statement said. </p> <p>"A story about the challenges and threats to the global food system, but also with ideas and suggestions for future innovations, that can help bring us closer to solving them." </p> <p>The tasting menu itself is priced at 3,200 Norwegian Krone ($316) with an optional wine pairing for 2,500 Norwegian Krone ($247). </p> <p>For those who want to visit the Salmon Eye, but don't want to dine in, they can buy a ticket for a two-hour "learning experience" at the centre priced at 349 Norwegian Krone ($34). </p> <p><em>Images: Salmon Eye Website/ Instagram, TikTok</em></p> <p> </p>

Judi Dench's tough health update

<p>Judi Dench has admitted that due to her degenerative eye disease she can barely see on a film set and can no longer read her scripts. </p> <p>The Oscar-winning actress known for her role as M16 head M in seven different <em>James Bond</em> films, told UK publication <em>The Mirror</em> that her age-related macular degeneration (AMD) has gotten so bad that she can now barely see. </p> <p>“I can’t see on a film set any more,” she told the publication. </p> <p>“And I can’t see to read. So I can’t see much. It’s difficult for me if I have any length of a part. I haven’t yet found a way.</p> <p>“But you just deal with it. I have so many friends who will teach me the script,” she added. </p> <p>The eight-time Academy Award nominee had previously said that she is unable to drive due to her AMD. </p> <p>“It’s the most terrible shock to the system. Ghastly. It’s terrible to be so dependent on people,” she had previously said. </p> <p>However, the actress is determined to maintain her independence and has no plans to stop working.</p> <p>“I have an irrational fear of boredom. That’s why I now have this tattoo that says carpe diem (“seize the day”). That’s what we should live by," she said. </p> <p>The actress has won various awards throughout extensive career including six BAFTAs, two Golden Globes and an Academy Award for Best Supporting Actress for her role as Queen Elizabeth I in <em>Shakespeare in Love</em>.</p> <p>Dench currently lives with her partner David Mills, and has shared how grateful she is to have someone so caring by her side. </p> <p>“I’ve had many, many good friends, but it’s been very unexpected to have somebody new who is as caring as my partner, David.</p> <p>“I feel very lucky indeed. And to laugh with somebody is terribly important! Laughing is the most important thing. We laugh about everything,” she said. </p> <p><em>Image: Getty</em></p>

Charles revives royal tradition at Trooping the Colour

<p>King Charles III revived a royal tradition by riding horseback in the first Trooping the Colour since he was crowned, marking the British sovereign’s official birthday.</p> <p>Although the King’s birthday is officially in November and typically celebrated privately, the ceremonial event on June 18 showcased all the pomp and pageantry expected of royal celebrations, drawing massive crowds to central London.</p> <p>Accompanying 1,500 soldiers, 300 horses and hundreds of musicians, Charles filed the short distance from Buckingham Palace to Horse Guards Parade in St James’ Park for the ceremony viewed by members of the royal family.</p> <p>It was a sight not seen for nearly 40 years, with Queen Elizabeth II being the last reigning monarch to ride in the procession in 1986.</p> <p>Dressed for the occasion, King Charles was wearing a Welsh Guard uniform, with a leek emblem on the collar and green and white plum on his bearskin.</p> <p>He was followed on horseback by various royal colonels including Prime William, also donning a uniform of the Welsh Guard, the regiment he inherited from his father in December 2022. He rode alongside Princess Anne Gold Stick in Waiting and Colonel of the Blues and Royals and Prince Edward, who is Colonel of the London Guards.</p> <p>Behind them was a horse-drawn carriage carrying the Queen, Catherine, Princess of Wales and her children Prince George, Princess Charlotte and Prince Louis. The royal party was joined by a Sovereign’s Mounted Escort of soldiers from the Household Calary’s Life Guards and Blues and Royals.</p> <p>The traditional military spectacle was flooded with well-wishers dressed in fascinators and draped in Union flags ahead of the parade to claim their prime position along the Mall outside the royal residence.</p> <p>Speaking to <em>CNN</em>, broadcaster and royal watcher Bidisha Mamata, said there was “a real sense of celebration”.</p> <p>"The coronation was very serious … there was a lot of medieval pageantry. This is much more military focused. This is so much more about connecting King Charles with his own history in the Marines, the RAF - he has a strong connection to the military," she said.</p> <p>The ceremony saw Queen Camilla join her husband to watch the 1st Battalion Welsh Guards troop their colour in front of hundreds of Guardsmen and officers.</p> <p>The regiment carried out complex battlefield drill manoeuvres to music, with Kensington Palace previously describing the 2022 musical program as having “a distinctly Welsh theme”, with new compositions from the band written accordingly.</p> <p>After the parade, the royal party returned to Buckingham Palace following the same route. They there made a balcony appearance to watch an extended military flypast and greet a sea of royal supporters.</p> <p><em>Image credit: Getty</em></p>

5 daily habits to improve heart, brain and eye health

<p><em><strong>Blackmores Naturopath Rebekah Russell shares her top five tips for boosting heart, brain and eye health.</strong></em></p> <p><strong>1. Stand up for your health</strong><br />Sitting is the new smoking. Sitting for hours on end, like most office workers do, increases the risk of heart attack and stroke – even if you are a regular exerciser. Unfortunately, a morning run or afternoon swim can’t negate the damage of sitting for eight hours or more a day. Try setting a diary reminder on your computer to stand up and walk around or try to stand during phone calls.</p> <p><strong>2. De-stress</strong><br />Despite modern technologies that are designed to make life easier, we’re all more stressed than ever. Long-term stress can spike levels of cortisol – a stress hormone which can affect the short-term memory regions of the brain. Meditation, spending time with friends and family, switching off from the Internet and social media, are all ways you can minimise stress and maintain long-term brain health.</p> <p><strong>3. Be a floss boss</strong><br />Not only can regular flossing prevent bad breath, it may prevent heart attack. While there is currently no definitive proof periodontal disease actually causes heart disease, there is proof that bacteria in the mouth can be released into the bloodstream and cause a hardening of the arteries. This can then lead to heart attack and stroke – reason enough to include flossing in your daily routine!</p> <p><strong>4. Good food</strong> <br />Good eye, brain and heart health all starts with the food on your fork. Try to include two serves of fruit and five serves of vegetables in your diet each day.</p> <p>Lutein (often referred to as the “eye vitamin”) and zeaxanthin, nutrients commonly found in vegetables, are disease-fighting antioxidants that are important for eyes, brain, and heart. Both nutrients are commonly found in green leafy vegetables such as spinach, kale, turnips and lettuce as well as broccoli, zucchini and brussels sprouts and eggs.</p> <p>Omega-3 fatty acids, found in fish and<strong> </strong>fish oil<strong>, </strong>may also help fight off macular degeneration and cataracts, while also maintaining good heart and brain health.</p> <p><strong>5. Get social</strong> <br />If you need another excuse to catch up with friends, or hang out with family, it’s this one! Socialising stimulates the brain and can also help to encourage healthy behaviours such as exercising. Daily social interaction has also been suggested to protect the brain against diseases including dementia and Alzheimer’s.</p> <p><em>Images: Getty</em></p>

<p>Getty photographer Chris Jackson has shared insight into what it was like to capture the coronation, and watch the moment King Charles III and Queen Consort Camilla walked out onto Buckingham Palace balcony from a unique perspective.</p> <p>Taking to Instagram, Jackson shared a rare image that gave the public a small sense of what Charles and Camilla would see from the balcony.</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/Cr6FZQwtiE6/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/Cr6FZQwtiE6/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Chris Jackson (@chrisjacksongetty)</a></p> </div> </blockquote> <p>"An honour to shoot 'behind the scenes' and a never seen before angle from today's historic Coronation, what a day!!!!!!

King Charles’ eye-watering net worth revealed

<p dir="ltr">The royal family’s net worth has always been up for speculation, but <em>The Times</em> has analysed the King’s various income streams and unveiled the King’s personal net worth.</p> <p dir="ltr">King Charles reportedly has a personal net worth of £600 million or around $1.1 billion.</p> <p dir="ltr">The King’s fortune surpasses the late Queen’s net wealth of £370 million or $684 million, by more than double the amount.</p> <p dir="ltr">A former aide told <em>The Times </em>that King Charles had managed to accumulate a significant net wealth over the years following his costly divorce from Princess Diana in 1996 - where he paid her a $31 million lump sum and $740,000 annual salary.</p> <p dir="ltr">“He became prudent at tucking away some money from the Duchy [of Cornwall] after that wipe-out [of capital],” said the source.</p> <p dir="ltr">The duchy is where most of King Charles’ income comes from.</p> <p dir="ltr">There are two duchies in the UK, the Duchy of Lancaster and the Duchy of Cornwall. Both of these property empires primarily invest in land.</p> <p dir="ltr">King Charles inherited the Duchy of Lancaster following his mother’s death last September, and Prince William is now in charge of overseeing the Duchy of Cornwall, which is estimated to be worth $1.8 billion.</p> <p dir="ltr">When King Charles was in charge of overseeing the Duchy of Cornwall, he had increased its annual profits by 42.6 per cent to $47 million between 2011-2022.</p> <p dir="ltr">He made $393.6 million from the duchy in that time period, which isn’t liable to tax, though King has been voluntarily paying income tax since 1993.</p> <p dir="ltr">A lot of the revenue comes from “renting commercial properties” from other parts of the UK according to <em>The Times</em>.</p> <p dir="ltr">The Duchy of Lancaster has $1.2 billion of net assets, and although the royal in charge of overseeing the duchies are not allowed to sell the assets, they can keep the annual revenue.</p> <p dir="ltr">Sandringham and Balmoral are a couple of other income streams for King Charles, with an estimated value of $453 million for Sandringham and $388 million for the Balmoral castle and its estate.</p> <p dir="ltr"><em>Image: Getty</em></p>

How pink became fashion’s colour of controversy: a brief history

<p>From the blush pink of royal mistresses to the hot pink of tabloid party girls, pink has gained a reputation for being a provocative colour for those who dare to wear it.</p> <p>Despite its various shades and the complexities of its cultural significance, it is a colour that is often branded with the same connotations of feminine frivolity and excess – whether girlish and innocent or womanly and erotic. </p> <p>So much so that worshippers at a North London church were ordered to remove pink chairs after an ecclesiastical judge claimed that the choice of colour scheme could <a href="https://www.thetimes.co.uk/article/church-sees-red-over-bright-pink-chairs-3trg9xpgk">“cause puzzlement”</a>.</p> <p>This pink panic invites the question: why is pink so controversial? </p> <p>A brief glimpse at its rather colourful history in the Western world reveals associations that both shape and challenge what pink means.</p> <h2>Pink’s past</h2> <p>According to historian <a href="https://thamesandhudson.com/pink-the-history-of-a-punk-pretty-powerful-colour-9780500022269">Valerie Steele</a>, the birth of pink in modern fashion began in the 18th century. By this period, pink had become the colour of choice among courtly elites of the Western world, including royalty and aristocrats.</p> <p>Developments in dye making and the French court’s penchant for cutting-edge garments provided the perfect pairing to begin pink’s success as an emerging fashion staple.</p> <p>Perhaps the most instrumental influence on pink’s power was Madame de Pompadour – the mistress of King Louis XV. She was often portrayed by the painter François Boucher sporting her signature pink gowns and shoes, most notably in his 1759 piece <a href="https://www.theguardian.com/culture/2001/sep/08/art">Madame de Pompadour</a>.</p> <p>In his 1758 painting, <a href="https://harvardartmuseums.org/collections/object/303561">Madame de Pompadour at Her Toilette</a>, she is shown applying rouge from a box of cosmetics – the blushed cheeks implying female sexuality. For Steele, the colour pink in this period becomes attached to both the frivolity of French high fashion and the eroticising of white femininity.</p> <p>From the 18th century court to the 20th century home, pink gained further traction in the 1950s. As British professor of design history <a href="https://books.google.co.uk/books/about/As_Long_as_It_s_Pink.html?id=By0qAAAAYAAJ">Penny Sparke</a> writes: “Linked with the idea of female childhood, [pink] represented the emphasis on distinctive gendering that underpinned 1950s society, ensuring that women were women and men were men.”</p> <p>Whether <a href="https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjvufXu-vb7AhVJi1wKHY_RCrIQFnoECCYQAQ&url=https%3A%2F%2Fwww.lofficielusa.com%2Ffashion%2Fhistory-behind-jackie-kennedy-pink-suit-chanel-jfk&usg=AOvVaw2gvTMarBjpgCPRBDcV2AwN">adorning first ladies</a>, Hollywood stars or housewives, pink in this era represented a traditional femininity grounded in fixed gender roles.</p> <p>Marilyn Monroe’s iconic pink gown in <a href="https://www.imdb.com/title/tt0045810/">Gentleman Prefer Blondes (1953)</a> paired with her <a href="https://www.bloomsbury.com/uk/stars-9781838718374/">typecast “dumb blonde” film roles</a> and her <a href="https://www.huffingtonpost.co.uk/entry/a-visual-history-of-marilyn-monroe-pin-up-icon_n_56ba8d67e4b0c3c5504f5ee4">pin-up past</a> work together to reinforce the star as a sex symbol to be desired by audiences. As film scholar <a href="https://www.routledge.com/Heavenly-Bodies-Film-Stars-and-Society/Dyer/p/book/9780415310277">Richard Dyer</a> argues, Monroe represented the epitome of sex in conversative 1950s American society.</p> <p>On the other end of the scale, the first lady of the United States Mamie Eisenhower – wife of president Dwight D. Eisenhower (1953-1961) – cultivated an image of the ideal housewife through her famous “First Lady Pink” looks.</p> <p>Her stunning <a href="https://www.si.edu/newsdesk/photos/mamie-eisenhowers-inaugural-gown-1953">1953 inaugural outfit</a> was a sparkling pink gown embroidered with more than 2,000 rhinestones. She was well-known for her love of all things pink and transformed the White House with this colourful décor, so much so that the household staff called it a <a href="https://www.nps.gov/museum/exhibits/eise/Mamie/personal_interests/EISE3765_scale4.html">“Pink Palace”</a>.</p> <h2>Punk and protest</h2> <p>Beyond the 1950s, pink moved away from its associations of conformity and took on a new purpose: resistance.</p> <p>Paul Simonon, bassist for English punk band The Clash, <a href="https://www.economist.com/1843/2018/09/20/in-the-pink-the-fashion-history-of-a-divisive-colour">famously said</a> that “pink is the only true rock and roll colour”.</p> <p>We can certainly see this in the way that punk musicians reappropriate the sweet and girlish connotations of pink to create subversive performances.</p> <p>For her <a href="https://www.theguardian.com/arts/pictures/image/0,8543,-10704677171,00.html">1999 performance at Glastonbury</a>, Hole’s Courtney Love – notorious for her raw and raucous vocals – unexpectedly swapped her rebellious grunge girl look for a pink costume of ballet slippers and fairy wings.</p> <p>Pink is also the colour of feminist activism. The 2017 women’s march saw protesters taking to streets in pink “pussy hats”. </p> <p>They were responding to <a href="https://www.nytimes.com/2016/10/08/us/donald-trump-tape-transcript.html">a recording</a> of then president Donald Trump, in which he boasted about <a href="https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiO4Z7P-_b7AhVMEsAKHdtLBAgQFnoECAoQAQ&url=https%3A%2F%2Ftheconversation.com%2Ffrom-chaucer-to-trump-sexist-banter-has-been-defended-as-entertainment-for-600-years-84804&usg=AOvVaw0dCQPpZyNUtNJACNJ7CANh">grabbing women “by the pussy”</a>.</p> <p>This explicit connection between pink, female genitalia and activism is a feminist statement that emphasises women’s lack of autonomy over their own bodies in a patriarchal society.</p> <h2>Pink reclaimed</h2> <p>The connotations of pink are not fixed, but malleable. Whether worn by film stars, musicians or celebrities, the colour takes on new meanings through irony and reclamation.</p> <p>The 2001 film <a href="https://www.imdb.com/title/tt0250494/">Legally Blonde</a> subverts the gendered <a href="https://www.routledge.com/Neo-Feminist-Cinema-Girly-Films-Chick-Flicks-and-Consumer-Culture/Radner/p/book/9780415877749">“dumb blonde” stereotypes </a>associated with wearing pink by following the successes of a sorority girl who goes to law school.</p> <p>When Madonna donned her pink Material Girl look, she positioned herself as <a href="https://mcfarlandbooks.com/product/the-performance-identities-of-lady-gaga/">the new Marilyn Monroe</a>: a blonde bombshell for the era of Second Wave Feminism. She reworked Monroe’s tragic stardom into a narrative about female empowerment and survival.</p> <p>On TikTok, the <a href="https://www.refinery29.com/en-gb/2020/12/10217066/tiktok-bimbo-gen-z-trend">#Bimbo trend</a> involves feminine-presenting content creators finding inspiration in the once derogatory “bimbo” label. Their videos <a href="https://www.theguardian.com/commentisfree/2022/mar/23/the-bimbo-is-back-and-as-a-feminist-i-couldnt-be-more-delighted">reclaim the label</a> as a playful aesthetic and a new feminist lifestyle.</p> <p>Despite its longstanding associations with feminine frivolity and excess, pink consistently proves itself to be a transgressive colour. It moves with the times and does not shy away from parodying its own past.</p> <p>If Paris Hilton’s <a href="https://www.vogue.co.uk/fashion/article/paris-hilton-versace-show">surprise runway appearance</a> earlier this year in sparkling pink Versace bridal wear tells us anything, it’s that pink should never be underestimated. It still has the power to shock, fascinate and make a statement.</p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/how-pink-became-fashions-colour-of-controversy-a-brief-history-196535" target="_blank" rel="noopener">The Conversation</a>. </em></p>
