Press Releases SUNGLASSES PROTECT EYES FROM HARMFUL RAYS YEAR-ROUND

(1/1/2000) - Sunglasses aren't just for hot fun in the summertime, say the American Optometric Association's eye care experts. Winter's rays contain the same amount of harmful ultraviolet radiation as summer sun and that means walking in some winter wonderland calls for the same high level of eye protection. AOA recommends sunglasses that block 99-100 percent of both UV-A and UV-B radiation; screen out 75-90 percent of visible light; are perfectly matched in color and absorption and free of distortion and imperfection; have gray (which does not modify colors), green or brown lenses. Look for labels, but remember: no uniform standard of labeling for sunglasses exists. Snow sport enthusiasts might want to look for a mirror coating, which can help the eyes cope with intense glare, and wrap-around frames, which offer added UV protection.
