Sc.<\/strong>\n      Eye Am | Eye Care and Medico-Aesthetics\n    <\/div>\n  <\/div>\n\n  <p>UV rays can damage the eyes and the delicate skin of the eyelids cumulatively over the course of a lifetime. Photokeratitis, pterygium, cataracts, macular degeneration: several serious eye conditions are directly linked to unprotected sun exposure. The good news is that consistent, adequate protection is enough to significantly reduce these risks.<\/p>\n\n  <p>We often think about protecting our skin from the sun. We rarely think about our eyes. Yet ultraviolet (UV) rays affect the internal structures of the eye just as much as the thin skin of the eyelids, and the damage builds up silently over the years.<\/p>\n\n  <h2>Why Your Eyes Need UV Protection, Even During Winter<\/h2>\n\n  <p>UV rays do not disappear with clouds or cold weather. Surfaces like snow, water, sand, and light-coloured pavement reflect UV rays and amplify their intensity. A cloudy day on the ski slopes can expose your eyes just as much as a sunny day at the beach. UV protection is not seasonal: it should be a year-round habit.<\/p>\n\n  <h2>Which Eye Conditions are Linked to UV Rays?<\/h2>\n\n  <div class=\"ea-stade\">\n    <h3>Photokeratitis: a sunburn on the eye<\/h3>\n    <p>Photokeratitis is essentially a sunburn on the cornea. It occurs after intense, unprotected UV exposure, whether on the water, on ski hills, or during a long day outdoors. Symptoms can include eye pain, light sensitivity, redness, a gritty sensation, and blurred vision. While often temporary, this condition is very uncomfortable and easily preventable with the right eyewear.<\/p>\n  <\/div>\n\n  <div class=\"ea-stade\">\n    <h3>Pterygium: a growth linked to outdoor conditions<\/h3>\n    <p>Pterygium is a growth of tissue on the surface of the eye, commonly associated with chronic exposure to sun, wind, and dust. More frequent in people who work outdoors or spend a lot of time outside, it can cause persistent eye irritation and redness. In more advanced cases, if the growth extends toward the centre of the cornea, it can affect vision.<\/p>\n  <\/div>\n\n  <div class=\"ea-stade\">\n    <h3>Cataracts: a risk increased by UV exposure<\/h3>\n    <p>Cumulative UV exposure is a recognized risk factor in the development of cataracts. This condition, characterized by a progressive clouding of the lens, can lead to blurred vision, increased light sensitivity, and reduced night vision. The lens does not regenerate: damage accumulated over decades will inevitably make itself known.<\/p>\n  <\/div>\n\n  <div class=\"ea-stade\">\n    <h3>Macular degeneration: protecting your central vision<\/h3>\n    <p>Prolonged UV exposure may also play a role in the development of age-related macular degeneration (AMD). This disease affects the macula, the area of the retina responsible for the precise vision needed to read, drive, or recognize faces. The oxidative stress caused by UV rays on retinal cells is a factor you can actually act on. Sunglasses that filter 100% of UVA and UVB rays offer straightforward, concrete protection.<\/p>\n  <\/div>\n\n  <h2>Do Children Need UV Eye Protection?<\/h2>\n\n  <div class=\"ea-mythe\">\n    <p><strong>Myth: not protecting children&#8217;s eyes makes them more resilient to UV rays.<\/strong><\/p>\n    <p>The opposite is true. The lens of a young child&#8217;s eye is more permeable to UV rays than an adult&#8217;s. All the rays absorbed during childhood accumulate, and their harmful effects appear over time. Starting eye protection early, with properly rated sunglasses and a wide-brimmed hat, is one of the most useful preventive steps you can take for your child&#8217;s long-term eye health.<\/p>\n  <\/div>\n\n  <h2>What Do UV Rays Do to the Eyelids?<\/h2>\n\n  <p>The skin of the eyelids is the thinnest on the human body. Yet when we apply sunscreen, the eyelids are often skipped. Like the rest of the skin, they can develop cancerous cells, including basal cell carcinoma, one of the most common skin cancers in that area.<\/p>\n\n  <p>Repeated UV exposure can also accelerate the aging of eyelid skin, causing wrinkles, loss of firmness, and pigmentation spots. A sunscreen formulated for the eye area, combined with wearing sunglasses, are the two most effective ways to protect this fragile zone.<\/p>\n\n  <h2>How to Protect Your Eyes From UV Rays<\/h2>\n\n  <p>The protective habits are simple, but they need to be consistent. Wear sunglasses that block 100% of UVA and UVB rays. Wraparound frames offer better protection by limiting light from entering through the sides. Add a wide-brimmed hat: it can reduce direct UV exposure to the eyes by around 50%.<\/p>\n\n  <p>Apply a sunscreen formulated for the eye area to protect the eyelid skin, a zone that is often overlooked. If you already wear prescription glasses, UV-treated corrective lenses are an option worth considering for everyday use. These habits apply in winter, at altitude, and on overcast days too. UV rays do not take a day off.<\/p>\n\n  <h2>The Eye Exam: Protecting Your Vision for the Long Term<\/h2>\n\n  <p>UV damage accumulates silently for years before showing up. A comprehensive eye exam allows your optometrist to quickly detect conditions like pterygium, cataracts, or changes to the macula, and to guide you toward the most appropriate preventive solutions for your situation.<\/p>\n\n  <div class=\"ea-cta\">\n    <p>Have questions about UV protection or want to get your eye health assessed?
