Cataract is a disease that causes proteins to break-down and gather around your eye lens. When protein clumps gather around your lens, your vision starts getting weak gradually. If you avoid such a situation for too long, you can loose your vision permanently. A Cataract Surgery is the optimum solution for this condition.
The idea of camera was taken from your own eyes. The lens inside the eye works like the lens of the camera. Light is focused on your retina to get vision. When you see things at different distances, your eye lens starts changing the focus accordingly.
Eye lens are thin and transparent. They are composed of water and protein. Protein in the eye lens is arranged in such a fashion that maintains clarity and makes light rays pass through it.
As we grow old, these protein structures start to form clumps around your lens. This is a cataract. A cataract grows more and more over time making larger clumps, thus, reducing the clarity in vision. Individuals who are affected with such a disease, find it very difficult to see.
There is no actual cause found behind the clouding of the lens that leads to cataract. However, there can be some health factors that are associated with developing a cataract situation. These factors include diabetes, eye injuries, hormonal changes, exposure of your eyes to harmful rays, etc.
One of the theory behind a cataract development shows that cataract is caused due to oxidative changes that take place over time in the human lens. Fruits and vegetables that are high in anti-oxidants can prevent some types of cataract disease. One must consult his/her physician to know about food items that are mainly responsible to keep your eyes healthy. At the same time, also make a note about what kind of food must be avoided, that can affect your vision or other areas of your eye.
