As we soak up the sun this summer, it’s essential to remember that while sunlight brings warmth and joy, it also poses risks to our eyes. Long-term exposure to UV rays can lead to various eye conditions. One of the most common is cataracts, where UV rays damage proteins in the eye’s lens. These proteins cloud up your natural lens, thus developing a cataract. Cataracts impair your vision and overtime require surgery to remove, placing an artificial lens in your eye instead.
UV radiation can also cause growths on the eye’s surface. Two common growths are a pterygium (pronounced tur-IJ-ee-um) and a pinguecula (pronounced pin-gwek-yoo-la). A pterygium, also called a surfer’s eye, is a raised, fleshy growth on the corner of your eye. A pinguecula, is a yellowish patch or bump on your eyeball, is similar to having a callus on your skin. These growths can be uncomfortable and may need to be removed if they grow large enough to affect your vision.
Prolonged exposure to UV rays can also lead to photokeratitis, or corneal sunburn, can cause temporary blindness and typically manifests within a few hours of exposure to intense UV rays. UV rays are intensified when reflected off surfaces like sand, water and snow. Additionally, just as with skin cancer, prolonged UV exposure can increase the risk of ocular (eye) cancer.
For these reasons, it is critical to take proactive steps to shield our eyes from the sun’s harmful rays:
- Wear Sunglasses: Wear sunglasses that block 100% of both UVA and UVB rays. Look for labels that specify UV 400 or 100% UV protection.
- Choose the Right Hat: A wide-brimmed hat can provide additional protection by shading your eyes and face from direct sunlight.
- Seek Shade: When possible, stay in the shade during peak sunlight hours, typically from 10 a.m. to 4 p.m. This reduces your overall UV exposure and gives your eyes a break from direct sunlight.
- Regular Eye Exams: Schedule routine eye exams with your doctor. They can detect early signs of eye damage and provide guidance on protecting your vision.
As we enjoy the summer months and outdoor activities, let’s prioritize our eye health by practicing UV safety. By wearing UV-blocking sunglasses, wide-brimmed hats, and taking other precautionary measures, we can significantly reduce the risks associated with long-term sun exposure.
Remember, your eyes are precious—guard them against the sun’s harmful rays and enjoy the sun safely this summer!
