Raleigh, N.C. — Many people protect their skin with sunscreen when they're outdoors, but they don’t always protect their eyes. Doctors say there are important health factors to consider when choosing sunglasses.
Ophthalmologist Dr. Carmen McLean says sunglasses should have 90 to 100 percent UV protection. Tinted lenses aren't enough, and many glasses, especially plastic ones, don’t have UV protection.
“Ultraviolet radiation can cause damaging effects to the eyes. It can cause things like macular degeneration and cataracts,” she said.
McLean says she talks to her patients about their specific outdoor activities so she can suggest the best protective lenses. She advises finding glasses that have side protection so rays can’t get in and slightly larger glasses that cover the skin.
Anyone who is concerned about their sunglasses can take them to an eye professional, who may have a UV measuring device.
