The causes of cataracts are unclear. The occurrence of cataracts may be related to ultraviolet light, oxidative damage, and mineral deficiencies and imbalances such as calcium, potassium, and magnesium in the lens.
There is no clear mechanism to explain the occurrence of cataract. Any various causes such as aging, heredity, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, and radiation can cause disorders of lens metabolism, resulting in clouding of lens proteins due to degeneration. The occurrence and development of cataract is a comprehensive result of the interaction and joint influence of multiple factors, and the pathological changes are also multi-level. Therefore prevention is directed at possible causes to pay attention in work and life, including: (1) special work should wear protective glasses, such as long-term outdoor, long-term high altitude, high latitude work, exposure to infrared (furnace front workers, kiln workers, etc.), ultraviolet, x-ray personnel (radiotherapy personnel) protection should be early, starting from young; (2) active treatment of eye diseases that can cause cataracts, such as uveitis, glaucoma (3) avoid trauma to the eye; (4) internal eye surgery can accelerate the formation of cataract; (5) certain drugs can form cataracts and should be used rationally; (6) such as long-term eye drops with glucocorticoids, long-term systemic application of anti-metabolic drugs, glucocorticoids, anti-tuberculosis drugs, chlorpromazine, etc.; (7) toxins, trinitrotoluene, etc.; (8) vitamin supplements, especially those with (8) Vitamin supplementation, especially vitamins with antioxidant effect: such as vitamin C; (9) Tobacco and alcohol can accelerate cataract formation, and tea can reduce the incidence of cataract; (10) Prolonged exposure to strong visible light or ultraviolet light can accelerate cataract formation.
The occurrence and development of cataract is a comprehensive result of the interaction and joint influence of multiple factors, which may be related to UV light, oxidative damage, lack and imbalance of minerals such as calcium, potassium and magnesium in the lens causing lens metabolic disorders, and can be accordingly paid attention to eye protection in working life.
