Sunglasses

Sunglasses have been popular with people for years, both for comfort and as a fashion
accessory. However as studies and research continue to demonstrate a relationship
between UV-A/UV-B exposure and ocular disease, the protection of the long-term health
of your eyes is yet another reason to wear sunglasses. In order for sunglasses to provide
adequate protection for your eyes, they should:

• Block out 99 to 100 percent of both UV-A and UV-B radiation;
• Screen out 75 to 90 percent of visible light;
• Have lenses perfectly matched in color and free of distortion and imperfection;
• Have lenses that are gray, green or brown.
