Hypericin (active ingredient in St. John's wort) photo-oxidation of lens proteins.

Doctors theorize that certain types of light and radiation contribute by causing the lens protein to oxidize and change character.

It also found evidence for glycation of human lens proteins caused by fructose.

The chaperone functions of α -crystallin may also help maintain the lens proteins, which must last a human for his/her entire lifetime.

A mature cataract is one in which all of the lens protein is opaque while the immature cataract has some transparent protein.

In the hypermature cataract, also known as Morgagnian cataract the lens proteins have become liquid.

Instead of evolving a new lens protein to make a lens-like structure in the photophore, the squid simply reached into its existing bag of tricks.

Expression studies in non-lens cells showed that the αB-crystallin, other than being a functional lens protein, is a functional small heat shock protein.

But they warn that excess vitamin C may actually damage lens proteins and ultimately cause cataracts.

Some medications react with lens proteins to form large molecules that can accumulate and make the lens lose transparency.
