Cataract

What is Cataract ?

The lens of the eye, the part that helps focus light onto the retina which in turn sends the visual signals to the brain, is made mostly of water and protein.When too much protein builds up, it clouds the lens blocking some of the light and impairing vision. That protein buildup is the formation of a cataract. It is not a growth, but rather a clouding or hazing of the lens. Hazy or blurred vision may indicate a cataract.

Who gets cataracts?

A significant number of people, aged 65 yrs or older, have some degree of cataract. In fact, developing cataracts is a normal part of ageing. That does not mean, however, that every senior will need treatment for cataract problems.
