Sunlight is usually harsher during summer, so make sure to wear your sunglasses every time you go out to protect your eyes from harmful UV rays. However, since not all sunglasses and eyeglasses are made with the same quality, it can be hard to tell when a pair is actually providing your eyes with enough UV protection.
Continue reading to learn more about the importance of UV protection for your eyes.
Why Is UV Protection Important?
The sun’s UV rays can harm your eyes and affect your vision. According to studies, the more time you spend in the sun, the greater your risk of developing cataracts as you get older. Other eye conditions — such as corneal sunburn, macular degeneration, retinal tissue damage and abnormal growths on the eye surface — have also been linked to excessive sun exposure.
Fortunately, sunglasses are an affordable and effective way to protect your eyes from the sun. Just make sure your pair of sunnies offers 100% protection against UV 400 or 100% protection against both UVA and UVB. Ideally, you should get your sunglasses from your optometrist to ensure a good fit and adequate protection.
How Can You Check if Your Sunglasses Offer Enough UV Protection?
You can have your sunglasses checked at an optical shop. Opticians use a photometer to test sunglasses, and they often do this for free. Alternatively, you can test your sunglasses using a UV flashlight and a newer U.S. bill, which should have UV-fluorescent fibers that glow under UV radiation. If these fibers still glow after placing your sunglasses between the UV light and the paper money, it means your sunglasses aren’t able to block UV radiation.
