Cataract is one of the most widespread disorders in our modern society. According to statistics, more than 22 million people in the US suffer from this problem.

It affects eye lens, making person's vision cloudy and extremely uncomfortable.

The lens is a transparent part of your eye, which focuses light on the retina (sensitive tissue that converts light into the nerve signals and delivers them to the brain).

If the lens loses its clarity, the image becomes blurred.

Water and protein are two components of the lens. While aging, protein molecules may stick together, clouding the lens area. As a result, the light flow to the retina gets reduced. This process is called cataract.

With passing time, this disorder progresses, making it more and more difficult to see well.

Even though, cataract is a common trouble among Americans, people often are not well-informed about it.
