There are many vision questions that people ask, especially about cataracts, because more aging people around the world seem to get cataracts. Cataract is an eye disease that affects the lens of the eye, making it progressively opaque as time passes.

The disease occurs mainly due to aging, although injuries or inherited genetic disorders can influence the risk of developing it.
