What is a 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. If the cataract gets worse, sight can be partially or completely lost until the cataract is removed.
How Quickly Does A Cataract Grow?
Certain types of cataracts progress quite rapidly and cause cloudy vision within a few months. Fortunately, these are relatively uncommon. Most cataracts develop gradually and do not require surgery for many months or years. In some instances, surgery is not required.
