Cataract A cataract is a clouding of the normally clear, transparent lens of the eye. A cataract is not a tumor or growth of new tissue over or in the eye. Rather it is a fogging and loss of clarity of the lens itself. The lens is located in the eye just behind the iris and the pupil. Light entering the eye is focused by the lens onto the retina. When a cataract forms, the lens is no longer able to focus the light clearly. Therefore, your vision becomes cloudy. An early cataract may cause few problems with vision.
