Whenever “cataract” is mentioned, people usually think of “elderly people” immediately. When you turn on the TV, almost all cataract commercials will have an “elderly patient” who speaks for himself. As a result, misconceptions such as that only the elderly get cataracts and that age is the main cause of cataract formation have started to influence the public, which is actually wrong. As the body is exposed to the sun for a long time, the eyes are exposed to UV rays for a long time. Under the influence of ultraviolet light, calcium ions in the crystal combine with phosphorus ions to form calcium phosphate leading to hardening and calcification of the crystal, thus clouding the crystal and thus forming a cataract. Cause 2: Endocrine disorders Secondly, it may be caused by endocrine disorders. Abnormalities in blood sugar, blood pressure, and blood lipids can cause fluctuating changes in atrial fluid, leading to clouding of the crystal and inducing cataracts. This is why the incidence of cataracts is higher in diabetic patients than in normal people. Reason 3: Age Due to the aging of cells, the ratio of free water in the cells decreases and the metabolism slows down, making it impossible for harmful substances to be eliminated from the body in time and accumulate in the body. At the same time, the lack of water also aggravates the cloudiness of the crystal and induces the formation and development of cataract. Doctor’s tip: Paying attention to sun protection and avoiding overeating can reduce the increased risk of cataracts. Supplementation with lutein, which enhances the antioxidant capacity of the eyes, can also help resist UV damage and prevent cataracts.
