A cataract is the progressive clouding of the crystalline lens inside the eye. The lens inside the eye works much like a camera lens, focusing light onto the retina for clear vision. It also adjusts the eye's focus, letting us see things clearly both up close and far away.

The lens is mostly made of water and protein. The protein is arranged in a precise way that keeps the lens clear and let’s light pass through it. But as we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract, and over time, it may grow larger and cloud more of the lens, making it harder to see.

Cataracts usually develop with advancing age, although in rare cases, they can be congenital (present at birth).

   Advancing age (most commonly)

How Quickly Do Cataracts Progress?


The pace of cataract progression varies with each individual even eye to eyes of each one. In some cases, cataracts may take years to develop, while in other cases early-stage cataracts will never progress to a degree that requires treatment.
