a clouding of the eyes crystalline lens that usually develops slowly
over time. (In the case of post-traumatic cataracts, however, they can
also occur very quickly.) It is the leading cause of poor vision in adults.
Symptoms: Dimmed or blurred vision, double vision, halos or glare around lights,
colours appearing less brilliant, feeling of a film over the eyes, frequently
cleaning eyes, difficulty driving or reading, and frequently changing
or cleaning glasses.
Treatment: If a cataract grows larger or denser, it can
be surgically removed. Its a safe procedure with a near 100 per
cent success rate. Following surgery, its normal to require a change
in spectacle correction.
Prevention: Wearing UV protection when outdoors is very
helpful. There is also some evidence to suggest that a diet high in beta
carotene (vitamin A), selenium and vitamins C and E have preventative
benefits. Avoiding cigarette smoke, air pollution and alcohol consumption
may also help.
