Sunglasses protect eyes against UV rays, skin cancer, AOA says.

South Carolina's Sun News (8/20, Leotta) reported that "sunglasses can protect the eyes from the harmful effects of ultraviolet (UV) rays." Optometrist Mark Saunders, O.D., explained that "some of the problems that can result from UV rays include macular degeneration, cataracts," and "pterygium," which is a "fibrous growth in the cornea that" can also be "caused by wind damage." The American Optometric Association (AOA) "notes that sunglasses can" also "protect against skin cancer of the eyelids and skin around the eyes." People "who are sensitive to the sun for other reasons -- for example, younger people, and those with lighter skin, eyes, and hair -- have increased risk for eye problems if they don't wear sunglasses."
