When vitamin A is lacking, the adaptability of eyes to dark environment decreases, and it is easy to suffer from night blindness in severe cases. Vitamin A can also prevent and treat dry eye. Therefore, you should take enough vitamin A every day. The best source of vitamin A is the liver, cod liver oil, milk and eggs of various animals. Carotene contained in plant foods can be converted into vitamin A in the body, such as carrots, amaranth, spinach, leeks, green peppers, sweet potatoes and oranges, apricots and persimmons in fruits.

Foods rich in vitamin B group:

A considerable amount of free vitamin B2 is stored in the retina of the eye. Vitamin B deficiency can lead to photophobia, tears, burning pain and itching, visual fatigue and eye spasm. Foods rich in vitamin B include whole grains, liver, yeast, yogurt, wheat germ, beans, milk (vitamin B2) and meat (vitamin B 1, nicotinic acid).

Foods rich in vitamin c:

Vitamin C is one of the components of the eyeball lens. If you lack vitamin c, you are prone to cataracts. Therefore, the baby should pay attention to the intake of foods rich in vitamin C in his daily diet, such as fresh vegetables and fruits, especially green peppers, cucumbers, cauliflower, Chinese cabbage, fresh dates, pears and oranges.

Foods rich in protein:

Lean meat, animal viscera, fish and shrimp, milk, eggs, beans and other foods are rich in protein, and protein is the main component of cells, and eyes are no exception. Tissue repair and renewal need to constantly supplement protein.

Foods rich in calcium:

Calcium has the effect of eliminating eye tension. Beans, green leafy vegetables, shrimp skin and milk are all rich in calcium. Cooking methods such as burning sparerib soup and sweet and sour sparerib can increase the calcium content. Make sure that the baby drinks 2 cups of milk every day to ensure calcium intake.

Food harmful to the eyes

Dessert encourages myopia.

According to Japanese experts, sweets can promote the development of myopia. This is because the sugar in sweets needs a lot of vitamin B 1 when metabolized in the human body. If the sugar intake in the body is too high, the vitamin B 1 will be relatively insufficient. Therefore, some experts suggest that the baby suffering from myopia should eat less sweets as far as possible, and can eat more white radish, carrot, cucumber, bean sprouts, vegetables, onions, brown rice and sesame seeds, which will be good for vision. Most babies love sweets, but enough is enough.

Eating too much garlic is harmful to the eyes.

Garlic is a good condiment, which has a certain preventive effect on many diseases, and it is really beneficial to eat it in moderation. However, if you eat too much garlic for a long time, especially those with eye diseases and those with frequent fever, hot flashes and night sweats, it will have adverse effects. Therefore, there is a folk saying that "garlic is beneficial and harmful to the eyes alone".

This is especially important in the treatment period of baby suffering from eye diseases, because Chinese medicine pays attention to taboos. It is generally believed that patients with eye diseases must abstain from garlic, onion, onion, ginger and pepper and other irritating foods during the treatment period, otherwise the curative effect will be affected. For example, some patients with eye diseases, although treated, can not avoid spicy food such as garlic, and the result is not good.

Chrysanthemum is eye-catching

For friends who often have to face computers, the health of their eyes will be greatly threatened. Some people drink a lot of water before going to bed to moisten dry eyes, but the next morning, their eyes will swell.

Hot drinks in winter and ice drinks in summer all taste good.

Food with eyesight improving effect

To protect vision and prevent eye diseases, we need to start from many aspects, among which paying attention to nutrition is also helpful to improve vision. In the daily diet, foods that can improve eyesight are:

(1) Foods rich in vitamin A are closely related to normal vision. If vitamin A is insufficient, the regeneration of rhodopsin is slow and incomplete, the dark adaptation time is prolonged, and in severe cases, night blindness is caused. If vitamin A in the diet continues to be deficient or insufficient, dry eye will appear, and the disease will further develop into corneal softening and corneal ulcer, as well as corneal folds and Pitt's spots. The best food sources of vitamin A are various animal livers, cod liver oil, fish eggs, poultry eggs, etc. Vitamin A contained in carrots, spinach, amaranth, alfalfa, sweet potatoes with red hearts, pumpkins, green peppers and other vegetables can be converted into vitamin A in the body.

(2) Foods rich in vitamin C can weaken the damage of light and oxygen to the lens of eyes, thus delaying the occurrence of cataracts. Foods containing vitamin C include persimmon pepper, tomato, lemon, kiwi fruit, hawthorn and other fresh vegetables and fruits. (3) Calcium, calcium is related to eyeball composition, and calcium deficiency can lead to myopia. Teenagers are at the peak of growth, and the calcium demand in the body is relatively increasing. If we don't pay attention to calcium supplementation, it will not only affect the bone development, but also reduce the elasticity of the developing eyeball wall-sclera and increase the internal pressure of the lens, which will lead to the elongation of the anterior and posterior diameter of the eyeball and lead to myopia. Foods containing more calcium mainly include milk and its products, shellfish (shrimp), bone meal, beans and bean products, egg yolk and dark green vegetables.

(4) chromium, chromium deficiency is easy to cause myopia, chromium can activate insulin, so that islets can exert their maximum biological effects. For example, insufficient chromium content in human body will hinder insulin's function of regulating blood sugar, and increase plasma osmotic pressure, resulting in increased osmotic pressure and diopter of eyeball lens and aqueous humor, thus inducing myopia. Chromium mostly exists in brown rice and wheat bran, and the liver, grape juice and nuts of animals are also rich.

(5) Zinc, zinc deficiency can lead to visual impairment, and zinc is mainly distributed in bones and blood in the body. Zinc is also contained in corneal epidermis, iris, retina and lens. Zinc participates in the substitution and transportation of vitamin A in the eye, maintaining the normal tissue state of retinal pigment epithelium and maintaining normal vision function. Foods containing more zinc include oysters, meat, liver, eggs, peanuts, wheat, beans and miscellaneous grains.

(6) Pearls, pearls contain more than 95% calcium carbonate and a small amount of minerals such as magnesium oxide and aluminum oxide, and contain a variety of amino acids, such as leucine, methionine, alanine, glycine, glutamic acid, aspartic acid, etc. Pearls are sweet, salty and cold, and the "Zhenzhu Powder" made of pearl powder with borneol and amber can inhibit the formation of cataracts.

(7) Kelp. Kelp contains1/3 mannitol in addition to iodine. There is a thick layer of "white frost" on the surface of dried kelp, which is mannitol in kelp. Mannitol has diuretic effect, which can reduce intraocular pressure and has a good effect on treating acute glaucoma. Other seaweeds such as Undaria pinnatifida also contain mannitol, which can also be used as an auxiliary food for treating acute glaucoma.

2. Health foods that help to improve eyesight can increase nutrition and improve eyesight through diet, so we should eat more of the above foods. If we can choose appropriate health foods that can improve eyesight on the basis of daily diet, it can play a good role in adjuvant therapy. The optional health foods are:

(1) Foods rich in vitamin A, such as medlar products.

(2) Rich in protein, peptides, certain amino acids, such as taurine, nucleic acids, etc.

(3) Health tea, granule or capsule containing cassia seed, chrysanthemum, hawthorn and pearl powder.
