But as we get older, some of the protein may possibly clump together and begin to impair a little area of the lens. This can be a cataract, and over time, it might grow larger and impair more of the lens, making it tougher to see.

Experts are gaining additional insights about what leads to these certain types of proteins (crystallins) to cluster in excessive ways to cause lens cloudiness and cataracts. One recent finding shows that fragmented versions of these proteins bind with normal proteins, disrupting regular function.

Cataracts are classified as one of three types:

Sub capsular cataract: Start at the back of the lens. Very common in people with diabetes, or people who take high doses of steroids.

Nuclear Cataract: This cataract forms in the center of the lens, and is due to natural aging.

Cortical cataract: Forms in the lens cortex, many diabetics develop it.
