Protecting eyes is not just dropping advanced eye drops, but more importantly, starting from eating habits. Because eyes need tears to moisten, and tears contain many nutrients, the most important of which is vitamin B2; The process of looking at things needs the participation of vitamin A; The conduction of optic nerve needs the help of vitamin B group; Preventing eye aging requires healthy blood vessels, and vitamin C and vitamin E are very helpful.
Vitamin A is a vitamin that we in China are easy to lack. In the absence of vitamin A, eyes often feel dry and tired easily. In severe cases, the eye surface is white and dry, and even leads to corneal ulcer. Before these symptoms appear, people's dark vision has been reduced and their dark adaptation ability is poor, that is to say, it is difficult to adapt from light to dark for a long time. Vitamin A supplementation should include liver, milk, egg yolk, green leafy vegetables, carrots and sweet potatoes.
