■ Pay attention to protein and calcium foods 1, and eat more foods with high protein content. Protein is an indispensable and important nutrition for eye tissue. If protein is not supplied for a long time, it will accelerate the aging of eye tissue, decrease its function and decrease its vision. Therefore, in order to prevent vision loss, we should supply rich protein diet in the diet, and protein should mainly take eggs, milk, meat, fish, bean products and other foods, and protein should take more than 80 grams of food every day. 2, pay attention to calcium supplementation. Calcium is the "protector" of eye tissue. If calcium is deficient in the body, it will not only cause the elasticity of the retina of the eye to decrease, the pressure in the lens to increase, and the anterior and posterior diameter of the eyeball to lengthen, but also cause degenerative diseases in the upper cornea and ciliary muscle, which may easily lead to vision loss or myopia. Therefore, in order to prevent vision loss, we should pay attention to supplying a diet rich in calcium and vitamin D in our daily diet (at the same time, supplying vitamin D is beneficial to the full absorption of calcium), such as milk, beans, fungi, dried fruits and seafood, which are rich in calcium, cod liver oil, animal liver, dairy products and egg yolk, and all of them are rich in vitamin D. Combining them organically can play a good role in supplementing calcium. ■ Pay attention to supplementing trace elements 1 and reasonably supplement trace elements. Trace elements such as sun, zinc and chromium are beneficial to improve eye tissue and prevent vision loss. For example, people can obviously improve their eyesight after injecting selenium or eating foods containing more selenium; The zinc content in retina and choroid is the highest; Chromium is closely related to vision loss and myopia. Therefore, in order to prevent vision degradation, we should pay attention to foods with high trace elements such as selenium, zinc and chromium. Foods rich in selenium include animal liver, eggs, fish, shellfish, soybeans, mushrooms, asparagus, shepherd's purse, carrots, etc. Foods rich in zinc include animal testicles, prostate, liver, kidney and milk, fish, cereals, beans and hard fruits. Foods containing more chromium include beef, black pepper, brown rice, corn, millet, coarse flour, brown sugar, grape juice, fungi and so on. 2. Eat more foods rich in vitamins. Lack of vitamins A, C and B2 not only makes the cornea dry easily, but also causes corneal softening and even blindness. Therefore, we should pay attention to eating foods with high vitamin content. Such as cod liver oil, animal liver, milk, egg yolk, fresh vegetables, fruits, soybeans and their products, hard fruits (peanuts, sunflower seeds, walnuts), mushrooms, coarse sugar, etc. ■ Dietotherapy for visual deterioration: patients with visual deterioration can choose the following dietotherapy methods: 1, take 4 grams of Fructus Schisandrae Chinensis (parched), green tea 1 gram, and 25 grams of honey. Decocting with water, daily 1 dose, has the function of clearing away liver heat and improving eyesight, and is suitable for vision loss, etc. 2. Take salt to fry Lycium barbarum 1 0g, white chrysanthemum10g, and black tea10g. Brewing in boiling water, drinking frequently instead of tea, daily 1 dose, has the functions of nourishing liver and kidney, clearing away liver heat and improving eyesight, and can be used for vision loss, night blindness, etc. 3. Take 2 eggs, 6-8 red dates, and 0/5-30g of Lycium barbarum/kloc. Stew the three herbs * * *, shell the eggs when they are cooked, and then cook them slightly. Every day or every other day 1 dose, divided into1-2 times, has the effect of nourishing yin and blood, and can be used for treating vision loss and other diseases; 4. Take pork liver150-200g, 2 eggs, 4-5 scallions, and appropriate seasonings such as salt, monosodium glutamate and yellow wine. Add water to pork liver slices and make soup. Beat in eggs and scallion, cook for a while, and add seasoning. Daily 1 dose, taken with meals, has the function of nourishing blood, and can be used for liver blood deficiency's vision loss, etc. Six kinds of foods to protect eyesight: 1, myopia to avoid vision decline, you have to eat more fish, grain, citrus fruits (oranges, tangerines, oranges, lemons) and red fruits. Be careful not to eat foods that aggravate myopia, especially all kinds of sweets, sweets, meat and full-fat cheese. 2. There should be more garlic, onions, dairy products (skim milk), dried fruits, animal livers, mackerel and polished rice on the menu of hyperopia people. You should also eat meat and vegetables cooked with meat oil properly. 3. The dietotherapy for cataract patients is to drink water, at least 1 liter of water every day; Secondly, it is good to eat more grain, green vegetables and lettuce, carrots and tomatoes, and eat more fruits, especially citrus fruits, grapes, lemons, bananas and apricots. Also eat calcium-containing foods (milk, cheese, yogurt) regularly. Avoid drinking, smoking and eating animal fat and sugar. 4. Presbyopia is related to crystal aging. Therefore, its dietotherapy method is the same as that of cataract. 5. Glaucoma is caused by high intraocular pressure. In order to reduce intraocular pressure, you should have garlic and onions in your menu. In addition, eat less greasy things, don't drink tea, coffee and wine, and quit smoking completely. 6. Dry eyes. Its dietotherapy is to eat all kinds of fruits (especially citrus fruits), lemons, grapes, green vegetables, grain, fish and eggs; Drink at least 750 grams of water every day. Supplementing protein: If the supply of protein is insufficient for a long time, it will affect the metabolism of eyes, resulting in decreased vision. Protein's richest sources are meat and meat products, milk and dairy products, and eggs. Pay attention to calcium supplementation: calcium deficiency can reduce the elasticity of sclera and increase the pressure in lens, which is easy to cause vision loss. Milk and dairy products contain the most calcium, followed by beans, shrimp skin and scallops. Pay attention to the intake of selenium and zinc: Eating foods rich in selenium can improve eyesight, such as animal liver, eggs and shellfish. Zinc-containing foods include oranges, apples, walnuts, melon seeds, peanuts, fish, eggs and meat. You should eat more foods containing more chromium: chromium has a certain relationship with vision loss and myopia. Foods containing more chromium include beef, brown sugar, grape juice, black pepper and brown rice. Eat more foods rich in vitamin B2: It can ensure the normal metabolism of retina and cornea. Without B2, eyes will be afraid of light, shed tears, get tired easily, and their eyesight will gradually decline. Eat more liver, cooked cheese and beans. Vitamin A supplement: The direct source is animal liver, oil, cheese, milk, eggs, cod liver oil, etc. Many vegetables contain a lot of carotene, which can be converted into vitamin A by human body, especially carrots, spinach and lettuce, and fruits are rich in oranges, persimmons and apricots. Supplementing sugar: sugar is one of the main nutrients of eye lens, which can moisturize eyes and prevent eye fatigue. There are many foods rich in sugar, including all kinds of foods, but candy, biscuits, syrup and fruit candy are the most abundant. Eating more vitamin B1:B1is too low, which may lead to nervous system inflammation, thus affecting the optic nerve and causing vision loss; Foods rich in vitamin B 1 include rye flour, meat, beans and animal liver. Eat more vitamin C: Long-term lack of vitamin C is prone to eye diseases, and it is rich in fresh vegetables and fruits, but attention should be paid to the storage, processing and eating methods to prevent the content of vitamin C from decreasing.
