Protect Your Eyes From the Sun

Sunlight is the primary source of UV radiation that can damage tissues of the eye. Excessive exposure can cause...damage to the cornea and conjunctiva; as well as increase the incidence of cataracts and macular degeneration.

Your best protection from sunlight, besides total avoidance, is the use of sunglasses. There are three types of these: cosmetic, general purpose and special purpose.

Cosmetic sunglasses are worn only as fashion accessories and give little protection to the eye from damaging rays. General purpose sunglasses reduce glare in bright light and protect the eye from both UVA (radiation within a wavelength of 315nm to 380nm) and UVB (radiation within a wavelength of 280nm to 315nm) rays. Special purpose sunglasses also reduce glare in bright light and block UV rays but are also designed to offer safety protection during sports or specific work-related situations.

When purchasing sunglasses, price is not always your best indication of quality. Check for adequate UV protection and tint, effective polarization, minimum lens distortion, maximum lens durability and good frame construction to ensure that you are getting the best protection available in your price range (Source: Membership Advantage, National Safety Council, Winter 2000, Vol. 3, Issue 1).
