Long term exposure to UV radiation can be much more serious. A number of scientific
studies and research have shown that exposure to small amounts of UV-B radiation over a
period of many years contributes to the development of cataract s; pterigia (tissue growth
on the surface of the eye); skin cancer around the eye; and can cause damage to the retina
(macular degeneration), the nerve-rich lining of your eye that is used for seeing. Damage
to the retina is usually not reversible.

While everyone is at risk of the harmful effects of UV-A and UV-B radiation, certain
people are at an increased risk because the effects of UV radiation are cumulative. This
means 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.
