A cataract is a progressive clouding of the
eye's natural lens. It is a gradual blurring of vision, usually
described as looking through a piece of wax paper. In the normal eye, light passes through a clear lens before it reaches the
retina. The lens focuses light on the retina. In an eye with a cataract,
the lens becomes cloudy. This clouding distorts rays of light and
prevents light from being focused on the retina. This results in
distortion of in one's vision. The lens of the eye is composed primarily
of protein. Cataracts are caused by changes in the chemical makeup of the
lens. With age, the lens becomes thicker and less clear.
