You can choose to eat animal liver, kidney, milk, cream and egg yolk, eat green leafy vegetables, carrots and all kinds of fresh fruits that can be converted into vitamin A.

Secondly, eat more foods containing vitamin B 1. Vitamin B 1 can protect optic nerve, maintain normal vision, prevent optic nerve degeneration and prevent eye diseases such as cataract.

Foods rich in vitamin B 1 mainly include animal liver, kidney, lean pork, egg yolk, coarse rice, coarse flour, soybean, sesame, barley, wheat, milk, Monopterus albus, buckwheat, germ, malt, chestnuts, peas and green leafy vegetables.

You should also choose more cold foods that clear the liver and improve eyesight, such as duck meat, duck eggs, snails, snakehead, mussels and so on.

In order to protect your eyes, you should also pay attention not to eat or try to eat less irritating and spicy foods such as pepper, garlic, pepper, curry, strong tea, liquor, cigarettes and fried foods. Because these foods are irritating and hot, it is easy to damage the optic nerve and blur the vision.
