Always Wear Sunglasses
UV radiation can hurt your eyes just like it does your skin. Effects add up and can cause problems like cataracts, cornea burns, and even cancer of the eyelid. Whenever you’re outside -- even on cloudy days -- wear sunglasses or contacts that block 99% to 100% of UV-A and UV-B rays. Protective lenses don’t have to be expensive, just check the label. Hats block exposure, too. Snow, water, sand, and concrete all can reflect UV rays.
