June 27 is International Sunglasses Day – a perfect reminder that protecting your eyes from ultraviolet (UV) rays is just as important as wearing sunscreen.
In Australia, we’re blessed with beautiful sunshine – but we also have some of the highest UV exposure in the world. And while most people associate UV damage with the skin, your eyes are just as vulnerable.
? Not Just Fashion – A Medical Necessity
Wearing sunglasses isn’t just about reducing glare or looking stylish at the beach. Proper UV-filtering sunglasses protect your eyes from serious, long-term conditions – some of which we see and treat regularly here on the Sunshine Coast:
? Pterygiums (Surfer’s Eye)
A pterygium is a fleshy growth on the white of the eye that can extend toward the pupil. It’s caused by chronic UV exposure, wind, and dust – especially in coastal or outdoor environments. It may cause redness, irritation, and even vision problems if left untreated.
➡️ Good sunglasses reduce your risk of developing a pterygium in the first place.
⚠️ OSSN (Ocular Surface Squamous Neoplasia)
UV damage can also cause more sinister changes. OSSN is a type of eye cancer that can appear similar to a pterygium but requires prompt diagnosis and surgical treatment. Early UV protection may reduce your risk of this serious condition.
?️ Cataracts
Over time, UV exposure accelerates clouding of the natural lens in your eye, leading to cataracts. While cataract surgery is very effective, the best protection is prevention – and that means daily sunglasses that block UV rays.
? Macular Degeneration
UV rays may also play a role in damaging the retina over time, contributing to age-related macular degeneration (AMD). AMD is one of the leading causes of vision loss in older Australians.
➡️ Sunglasses, particularly when combined with a wide-brimmed hat, help reduce cumulative UV damage to the retina.
? Eyelid Skin Cancer
The skin around the eyes is incredibly thin and sensitive. Up to 10% of all skin cancers occur on the eyelids, where sunscreen is often forgotten.
Sunglasses with large lenses or wraparound frames offer important protection for this delicate area.
? Not All Dark Glasses Protect Your Eyes
Here’s the catch: just because sunglasses are dark doesn’t mean they’re protective.
In fact, low-quality dark lenses can actually make things worse by causing your pupils to dilate – letting more UV in if the lenses don’t block it.
✅ Look for this:
Only sunglasses labelled “UV400” or “100% UV protection” block both UVA and UVB rays. But be wary of fakes!
This standard filters out wavelengths up to 400 nanometres – the full harmful UV spectrum.
?⚕️ Dr. Rylan Hayes Says:
“As an eye surgeon, I see the long-term effects of UV exposure every week – from early pterygiums to serious retinal or eyelid conditions. The best advice is simple: wear quality sunglasses every time you’re outside. Even on cloudy days.”
? Takeaway Tips for Eye Protection:
- ✅ Always choose sunglasses with UV400 or 100% UV protection
- ✅ Consider wraparound styles for maximum coverage
- ✅ Wear a hat for extra shielding
- ✅ Protect kids’ eyes too – UV damage starts early
- ✅ Book an eye exam if you’ve noticed any eye growths, redness, or vision changes
