When vitamin A is deficient, 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 sources of vitamin A are 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 B vitamins:

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 eyeball lens. If you lack vitamin C, you are prone to cataracts. Therefore, babies should pay attention to foods rich in vitamin C in their 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 offal, fish and shrimp, milk, eggs, beans and other foods are rich in protein. protein is the main component of cells, and eyes are no exception. Organization repair and renewal need to be constantly supplemented by protein.

Calcium can relieve 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. Ensure 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 will promote the development of myopia. This is because the sugar in sweets needs a lot of vitamin B 1 when metabolized by 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 babies with myopia should eat less sweets as far as possible, and can eat more white radish, carrots, cucumbers, bean sprouts, vegetables, onions, brown rice, sesame seeds, etc., which will be good for their eyesight. Most babies love sweets, but enough is enough.

Eating too much garlic is bad for your eyes.

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

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 avoid irritating foods such as garlic, onion, onion, ginger and pepper during treatment, otherwise the curative effect will be affected. For example, some patients with eye diseases, although treated, still can't avoid spicy food such as garlic, and the result is not good.

A food with eyesight improving effect

To protect eyesight and prevent eye diseases, we need to start from many aspects, among which paying attention to nutrition is also helpful to improve eyesight. 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, and the dark adaptation time is prolonged, which can cause night blindness in severe cases. If vitamin A in the diet continues to be deficient or insufficient, dry eye will appear, and the condition will further develop into corneal softening and corneal ulcer, as well as corneal folds and Pitt spots. The best food sources of vitamin A are various animal livers, cod liver oil, fish eggs and poultry eggs. Vitamin A contained in carrots, spinach, amaranth, alfalfa, red sweet potatoes, pumpkins, green peppers and other vegetables can be converted into vitamin A in the body.

(2) Foods rich in vitamin C can reduce 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 their growth, and the demand for calcium in their bodies is relatively increasing. If you don't pay attention to calcium supplementation, it will not only affect bone development, but also reduce the elasticity of the developing eyeball wall-sclera, increase the internal pressure of the lens, 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, dark green vegetables and so on.

(4) chromium, chromium deficiency is easy to cause myopia, chromium can activate insulin, so that islets can play the greatest biological effect. For example, if the chromium content in human body is insufficient, the function of insulin in regulating blood sugar will be hindered, and the osmotic pressure of plasma will increase, which will lead to the increase of osmotic pressure of eyeball lens and aqueous humor and the increase of diopter, thus inducing myopia. Chromium is mostly found in brown rice and wheat bran, and it is also abundant in animal liver, grape juice and nuts.

(5) Zinc, zinc deficiency will lead to visual impairment, and zinc is mainly distributed in bones and blood in the body. Corneal epidermis, iris, retina and lens also contain zinc. Zinc participates in the replacement and transportation of vitamin A in the eyes, maintains the normal tissue state of retinal pigment epithelium and maintains normal visual function. Foods containing more zinc include oysters, meat, liver, eggs, peanuts, wheat, beans and miscellaneous grains.

(6) Pearl, which contains more than 95% calcium carbonate and a small amount of minerals such as magnesium oxide and aluminum oxide, and contains a variety of amino acids, such as leucine, methionine, alanine, glycine, glutamic acid and aspartic acid. Pearl is sweet, salty and cold. The "Zhu Zhen Powder" made of pearl powder, borneol and amber can inhibit the formation of cataract.

(7) kelp. Kelp contains 1/3 mannitol in addition to iodine. There is a thick layer of "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 the treatment of acute glaucoma. Other seaweeds such as Undaria pinnatifida also contain mannitol, which can also be used as an auxiliary food to treat acute glaucoma.

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

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

(2) It is rich in protein, polypeptide and some amino acids, such as taurine and nucleic acid.

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