The UV Index developed by the U.S. Environmental Protection Agency (EPA) and the National Weather Service (NWS) has made many Americans more aware of the risks of sunburn and skin cancer from the sun's ultraviolet
But did you know UV and other radiation from the sun also can harm your eyes?
Extended exposure to the sun's UV rays has been linked to eye damage, including cataracts, macular degeneration, pingueculae, pterygia and photokeratitis
And new research suggests the sun's high-energy visible (HEV) radiation (also called "blue light") may increase your long-term risk of macular degeneration. People with low blood plasma levels of vitamin C and other antioxidants especially appear at risk of retinal damage from HEV radiation.
Dangers Of Ultraviolet Radiation To Your Eyes
To protect your eyes from harmful solar radiation, sunglasses should block 100 percent of UV rays and also absorb most HEV rays. Frames with a close-fitting wraparound style provide the best protection because they limit how much stray sunlight reaches your eyes from above and beyond the periphery of your sunglass lenses.
