Definition

A cataract is a clouding of the eye's lens that leads to decreased vision. The lens of the eye focuses an image onto the retina at the back of the eye. This is where an image is processed and then sent to the brain.

As the cataract matures, it often causes glare, as well as decreased vision, contrast, and color sensitivity.
