There are various causes of cataracts, so prevention of cataracts must first be addressed to the causes and noted separately.
1. Strengthen nutrition and health education for pregnant women, take appropriate calcium supplements, enhance physical fitness, prevent viral and bacterial infections, and enable healthy fetal development. Combine with eugenics, propaganda to avoid inbred marriage.
2.In addition to breastfeeding, infants should be properly supplemented with calcium and vitamins according to their age, especially attention should be paid to the intake of vitamin A and D.
3, the elderly should pay attention to nutrition, usually eat more food containing protein and vitamin C, E such as fish, eggs, milk, fruits, vegetables, etc.

Schools, kindergarten teachers and parents, pay attention to educating children not to play with sharp knives and scissors, wool needles, etc., pay attention to safety when burning firecrackers.
5, to prevent eye radiation damage. Where long-term exposure to infrared workers, such as glass blowers must wear special glasses containing iron oxide and other metals; radiation therapy should be used to protect the eyes of lead; microwave workers should wear special microwave protective glasses.
UV eye damage, in addition to the mountains, snow can cause, in the ocean, desert, salt, ice can also cause the same eye disease. Because water and ice can reflect 70% of the ultraviolet rays, sand can reflect 30% of the ultraviolet rays, but the situation is not as serious as the mountains. In beach bathing areas, we see tourists wearing a pair of sunglasses, which not only can avoid sun glare, but also can prevent eye pain caused by long-term exposure to UV rays. From the perspective of cataract prevention, it is more important to avoid the chronic radiation of ultraviolet light.
6.Actively treat inflammation or degenerative diseases of the eye. Some lesions of the eye such as uveitis, retinitis pigmentosa, retinal detachment and high myopia can cause concurrent cataract.
7, perseverance and persistent treatment of diabetes. Diabetes mellitus, especially those with poor blood sugar control, has a catalytic effect on the occurrence and development of cataract. Statistics confirm that the age-related cataracts of diabetic patients are about 10 years earlier than the age of cataract maturity of the normal population.
