Cataract Causes and Symptoms

A cataract is an opacification of the lens that occurs over time as people age and just like a camera has a lens in it, the eye requires a lens in it to focus images on the back of the eye.

Now most of the time this is a slow process, but occasionally it can happen more rapidly, and that can be if somebody’s had trauma in the eye, if they’ve inflammation inside of the eye, if they’ve had surgery in the eye, or sometimes if they have certain medical conditions they are required to take medication for a certain amount of time.
