What is the best for myopia?

1. Protein: Protein is the basic substance of human life activities and consists of more than 20 kinds of amino acids. In the case of scleral tissue, it can become a tough, tough outer shell of the eye. Although the sclera has a certain degree of toughness, such as poor resistance and then affected by external forces. Will be forced to stretch, so that the eye gradually become longer, partial eclipse, picky eaters are detrimental to health, more disadvantageous to myopia. Fish, meat, milk, eggs are rich in protein.

2, calcium and phosphorus: calcium and phosphorus are the main components of the sclera, its high content, play a major role in enhancing the toughness of the sclera. At the same time to fully supply vitamin D to promote the absorption and utilization of calcium. This has an effect on enhancing development and preventing myopia. Food animal bones such as bovine bone and pork bone are rich in calcium and are absorbed and utilized by the body. Others such as milk, beans, oysters, crabs, shrimp, eggs, leeks, rape, peanuts, jujube and other calcium content is also higher; and milk, eggs, fish, meat, vegetables, coarse grains and seaweed, beans Vegetables, walnut meat, pumpkin seeds and other foods have more phosphorus content.

3, zinc and chromium: zinc and chromium are essential trace elements in the human body, especially zinc has more effect on the intraocular tissue, myopia patients generally lack of zinc and chromium, so they have to add food containing zinc and chromium, very necessary. Such as soybeans, oat flour, almonds, seaweed, kelp, lamb, steak, yellow fish, jellyfish, oysters, milk powder, cocoa powder, tea and other zinc content; yeast, beef, cereals, meat, liver and cheese, etc. Chromium content is higher. Can choose to serve.

4, vitamins: vitamins are necessary to maintain normal growth and development, play an important role in regulating the physiological function of the body, myopia more use of vitamin A, B1, B2, D, C and E treatment, this is because these vitamins can improve The nutrition and metabolism of the retina, optic nerve and other tissues in the eye also play a role in enhancing the toughness of the sclera and the muscle strength of the ciliary muscle. Among them, vitamin D can promote the absorption of calcium and phosphorus, and maintain the absorption of calcium and phosphorus in the body. As well as their proportional balance, children are provided with as much calcium and vitamin D as possible. Vitamins can not be synthesized in the body, must rely on food supply, animal liver, dairy, eggs, cod liver oil and other vitamin content is higher, fresh fruits contain a lot of vitamin C, beans, peanuts, etc. have a certain content.

5, tonic liver and kidney food: Chinese medicine believes that the cause of myopia, mainly due to liver and kidney deficiencies, blood loss, so the treatment can be used to restore liver and kidney function of food and drugs. Food such as meat, eggs, liver, kidney, eel, yellow fish, cuttlefish, mussels, sea cucumber, shrimp, turtle and longan, litchi, grapes, walnut meat, mulberry, jujube, etc. have the above role.
