There are many causes which can make young people suffer from cataract. But the main factors are:
First, nutrient metabolism. The lack of certain vitamins and trace elements can relate to cataract, such as calcium, phosphorus, vitamin E, A and B2.
Second, hardening dehydration, in the case of dehydration, the body’s fluid metabolism will disorder, which can produce unusual substances, and damage the lens.
Third, the temperature of the outside world, higher temperature can make lens easy to degenerate, and the probability for people suffering from cataract is greater.
Fourth, lack of oxygen, in the situation of oxygen deficiency, the calcium and vitamin will decrease in lens, but the lactic acid will increase, which can promote cataract.
Fifth, endocrine, endocrine disorder can promote cataract. Sixth, sunlight and ultraviolet light, under the influence of ultraviolet rays, phosphate ions may combine with calcium in the aging lens, which can form insoluble calcium phosphate, and then result in hardening and calcification of lens.
