A cataract is a clouding of the lens of the eye that can impair vision. The Cataract factors that may augment a person’s risk of developing cataracts include smoking, air pollution, or heavy alcohol consumption.
Age-related cataracts This type of cataract grows as a result of aging.
Congenital cataracts Babies are sometimes born with cataracts due to some infection, injury, or poor growth before they were born. They may develop cataract during their childhood as well.
Secondary cataracts This kind of cataracts happens due to a few medical conditions, like diabetes, or due to revelation to toxic substances, certain drugs (such as corticosteroids or diuretics), ultraviolet light, or radiation as well.

Causes For Cataract
Our eye functions are much like a camera. Like cameras, light rays enter the eye, passing through the cornea (the aqueous humor — transparent fluid in the front of the eye) and then the pupil and into the lens. The lens bends the light rays to focus objects onto the retina lining the back of the eye. From there, the image passes through the retinal cells, into the optic nerve, and finally to the back of the brain which process the images.
Cataracts take place when there is a buildup of protein in the lens. This protein makes it cloudy, which in result prevents light from passing easily through the lens. As a result, there happens some loss of vision. As new lens cells get formed on the outside of the lens, all the old cells are getting packed in the center of the lens resulting in the cataract disease.
