What part of the eye causes blindness?
A cataract is the clouding of the lens. Crystallins are water-soluble structural proteins found in the lens of the eye; these are what are responsible for the transparency in the lens. These proteins are arranged in a precise way that keep the lens clear and let light pass through it. As we age, the proteins begin to clump together causing that part of the lens to cloud. Essentially it is the lens that is affected.
What is the most prevalent type of cataract?
A cataract is the clouding of the lens in the eye preventing normal vision by restricting light passage through the lens. The most common type of cataract due to unprotected exposure to sun rays is nuclear cataracts. Cataract affect people usually as they age due to the changes in the proteins in the lens.
