How to prevent cataracts?

No matter who you are, you should pay attention to preventing the occurrence of cataracts in your life. You must drink plenty of water to prevent dehydration and ensure normal body metabolism. At the same time, you should also pay attention to supplementing enough vitamin C and eat more fresh vegetables and fruits.

1. Drink more water : When dehydration occurs, the normal metabolism of fluid in the body will be disrupted, which will produce some abnormal chemicals that damage the lens and lead to the occurrence of cataracts. For patients who already have cataracts, dehydration can aggravate the condition.

2. Therefore, if you encounter diarrhea, vomiting caused by various reasons , or sweat a lot under high temperature conditions, you should replenish water in time. In general, you can drink boiled water, tea or light salt water.

3. Eat more spinach and cabbage : A study by Harvard Medical School in the United States found that people who often eat foods rich in lutein and zeaxanthin (such as spinach, cabbage, etc.) are less likely to suffer from cataracts than other people.

4. Take in enough vitamin C: The vitamin C content in the human eye is about 30 times higher than that in the blood. However, with age, the nutrient absorption and metabolic functions gradually decline, the lens is malnourished, and the vitamin C content decreases significantly. Over time, it causes lens degeneration and leads to the occurrence of cataracts. Therefore, the elderly should eat more fresh vegetables and fruits and take in enough vitamin C.

5. Wear dark glasses when going out : The longer you are exposed to the sun's ultraviolet rays, the greater the possibility of developing cataracts. Researchers point out that wearing dark glasses when going out can greatly reduce the amount of ultraviolet radiation exposed to the eyes. Elderly people with declining vision after the age of 60 can prevent further vision loss and the occurrence of cataracts by wearing brown sunglasses.

6. Drink red wine in moderation: A study shows that drinking red wine in moderation can help reduce the risk of cataracts. The study found that people who drink red wine in moderation have a 50% lower risk of developing cataracts.
