Recent studies by British researchers show that diet and environmental factors play a role in the development of cataracts. According to this study, genetic factors play a 35% role in the occurrence and development of cataracts, and the share of environmental and dietary factors in the incidence of this complication is 65%.

This study examines the visual and nutritional status of 324 patients and shows that vitamin C plays an important role in reducing the incidence of cataracts, and by following a diet containing this vitamin, this disease can be largely prevented. Vitamin C or ascorbic acid is a water-soluble nutrient with antioxidant properties. This vitamin is essential for strengthening the immune system and protecting the skin and hair. Citrus fruits, tomatoes, squash, cabbage, spinach, melons and cantaloupes, turnips, bell peppers, pineapples, peas and kiwis are all rich in vitamin C. Vitamin C is effective in strengthening the immune system. In addition, some of the most important functions of vitamin C in the body are: A powerful antioxidant for collagen production Collagen is the main protein in the human body and is found in the bones, skin, tendons and other connective tissues of the body. So far, 28 types of collagen have been identified in the human body, of which types I, II and III are the most abundant and constitute 80 to 90% of all collagen in the body. Types I and III are found mainly in the skin and bones, and type II is found mainly in the joints. Collagen is produced naturally in the body and the amount of this protein decreases significantly with age. Vitamin C has an effective role in collagen formation in the body. Vitamin C is also essential for the growth and protection of blood vessels, body tissues and cartilage. Reduce stress and deal with high blood pressure Stress can affect hormone production and the menstrual cycle, fertility and immune function. Vitamin C is one of the essential vitamins for reducing stress. New studies by Mayo Clinic researchers show that vitamin C is also effective in lowering blood pressure. The need to take this vitamin during pregnancy and lactation Studies show that the amount of vitamin C needed by the body during pregnancy decreases. Vitamin C consumption during pregnancy reduces the complications of pregnancy and is effective in fetal growth. Vitamin C is effective in improving iron absorption Vitamin C improves iron absorption and thus fights anemia. Reduces the risk of heart disease. Helps regulate the menstrual cycle. Vitamin C is effective in regulating the menstrual cycle by increasing estrogen levels and decreasing progesterone levels. What is the required amount of vitamin C per day? According to studies, depending on age, 65 to 115 mg of vitamin C per day is sufficient. Girls aged 13 to 15 need about 66 mg per day, girls aged 16 to 18 need about 68 mg per day, women need about 65 mg per day, pregnant women need about 80 mg per day, and lactating women need about 115 mg per day. Overuse of this vitamin is harmful. According to the World Health Organization, cataracts are the leading cause of blindness in the world and affect about 20 million people annually. Prolonged use of steroids, diabetes, severe trauma to the eyes, prolonged exposure to sunlight without glasses and family history are the most important causes of cataracts. Sensitivity to light, painless blurring, decreased night vision, frequent rising eye score and two noses in one eye are the most common symptoms of cataracts.
