Each eye has a lens that works much like a camera. Light enters through the lens and is focused by these lenses and projected onto a delicate membrane lining on the inner eye (retina). The retina is a collection of light-sensitive cells at the back of the eye. When the light comes in contact with the retina these cells change the light into nerve impulses where the brain then interprets these impulses which allows people to see.
Smoking increases the chances of a person developing cataracts two to three times of that of a nonsmoker. Worldwide cataracts account for the leading cause of blindness.
By quitting smoking you lower your risk of developing cataracts.
