Yes, generally speaking, cataracts are most usually seen among the group of people who are more than fifty years old. In spite of this, nowadays with the increasingly serious working and living pressure and the environment pollution, many young people also began to get cataracts. As time goes by and the age augments, the crystalline lenses will degenerate and become muddy, which is caused by the accumulating deposits of wastes in the eyes and the decreasing oxygen permeability of the crystalline lenses. The crystalline lenses thus gradually lose their transparency and the vision gradually becomes blurry and at last the people become blind. To avoid cataracts, people should take in more vitamin C, which can effectively prevent and reduce the degeneration of the crystalline lenses as well as the formation of the muddiness. And do not overuse the eyes, and pay attention to allow the eyes to have adequate rest and sleep. When you are in the open on a sunny day, it is better to wear a pair of sunglasses with polarized lenses.
