Protect Your Eyes With Quality Sunglasses

Scientific research has shown that exposure to even small amounts of UV radiation over a period of many years may increase your chance of developing a clouding of the lens of the eye called a cataract and can cause damage to the retina, the nerve-rich lining of your eye that is used for seeing. Damage to the lens or the retina is usually not reversible.
The effects of UV radiation are cumulative. The longer your eyes are exposed to UV radiation, the greater the risk of developing conditions such as cataracts in later life. Therefore, you should wear quality sunglasses that offer good protection and a hat or cap with a wide brim whenever you are working outdoors, participating in outdoor sports, taking a walk, running errands or doing anything in the sun.
To provide protection for your eyes, your sunglasses should block out 99 to 100 percent of both UV-A and UV-B radiation; screen out 75 to 90 percent of visible light; be perfectly matched in color and free of distortion and imperfection; and have lenses that are gray, green or brown.

If you spend a lot of time outdoors in bright sunlight, wrap around frames provide additional protection from the harmful UV radiation.
