Abstract: calcium: calcium is the main component of bone and sclera. High calcium content plays a major role in enhancing the tenacity of sclera and eliminating eye tension. Therefore, the lack of calcium can reduce the elasticity of the eye wall, lengthen the eye axis and form myopia; Eye muscles are easy to fatigue and deepen myopia., Many people believe that children’s vision loss comes “quietly”. When they find that the vision is blurred, it is done. In fact, before vision loss, the occurrence of myopia is premonitory. Among them, diet can partly reflect the omen of myopia. Studies have shown that malnutrition / insufficiency / excess can change the normal physiological function of the eye retina and make pathological changes in diopter and myopia. The reasons are as follows: 1. Chromium: lack of chromium will make the lens convex, and the diopter of the eye will increase and myopia will appear. 2. The food contains more chromium in coarse grains, Hongtang, beans, yeast, beef, Cereals, meat, liver and cheese., 2. Zinc: zinc deficiency in some tissues of the eyeball will affect the photochemical process and make vision abnormal., The food contains more zinc, such as soybean, oatmeal, almond, laver, kelp, steak, mutton, yellow croaker, sea snails, oysters, milk powder, cocoa powder and tea., 3. Calcium: calcium is the main component of bone and sclera. High calcium content plays a major role in enhancing the tenacity of sclera and eliminating eye tension. Therefore, the lack of calcium can reduce the elasticity of the eye wall, lengthen the eye axis and form myopia; Eye muscles are easy to fatigue and deepen myopia., The bones of cattle, pigs and sheep are rich in calcium, and other foods such as milk, beans, fish, meat, shrimp skin, shrimp, eggs, rape, cabbage, laver, peanuts, jujube, walnut meat and pumpkin seeds are also rich in calcium., 4. Lead: adolescents at the stage of growth and development have a greater demand for lead than adults. If the lead element is insufficient, it can reduce the blood glucose regulating function of insulin and change the osmotic pressure of intraocular lens and aqueous humor. When the osmotic pressure of aqueous humor is lower than that of lens, aqueous humor will enter the crystalline body, which will make the lens convex and cause myopia., However, excessive lead will cause lead poisoning. Once it occurs, it will cause various visual dysfunction, mainly including retinal edema, retrobulbar optic neuritis, optic nerve atrophy, eye movement disorder, abnormal pupil regulation, blind spot, abductor paralysis, visual field change, etc.,

many people believe that children’s vision loss comes “quietly”. When they find that the vision is blurred, it is done. In fact, before vision loss, the occurrence of myopia is premonitory. Among them, diet can partly reflect the omen of myopia. Studies have shown that malnutrition / insufficiency / excess can change the normal physiological function of the retina of the eye and cause pathological changes in diopter, resulting in myopia. The reasons are as follows:

1. Chromium: lack of chromium will make the lens convex, and the diopter of the eye will increase, resulting in myopia. The food contains more chromium in coarse grains, Hongtang, beans, yeast, beef, Cereals, meat, liver and cheese.

2. Zinc: zinc deficiency in some tissues of the eyeball will affect the photochemical process and make vision abnormal.

and

foods contain more zinc, such as soybeans, oatmeal, almonds, laver, kelp, steak, mutton, yellow croaker, sea snails, oysters, milk powder, cocoa powder and tea.

3. Calcium: calcium is the main component of bone and sclera. High calcium content plays a major role in enhancing the tenacity of sclera and eliminating eye tension. Therefore, the lack of calcium can reduce the elasticity of the eye wall, lengthen the eye axis and form myopia; Eye muscles are easy to fatigue and deepen myopia.

and

foods are rich in calcium in bones such as cattle, pigs and sheep. Other foods such as milk, beans, fish, meat, shrimp skin, shrimp, eggs, rape, cabbage, laver, peanuts, jujube, walnut meat and pumpkin seeds also contain more calcium.

4. Lead: adolescents at the stage of growth and development have a greater demand for lead than adults. If the lead element is insufficient, it can reduce the blood glucose regulation function of insulin and change the osmotic pressure of intraocular lens and aqueous humor. When the osmotic pressure of aqueous humor is lower than that of lens, aqueous humor will enter the crystalline body, which will make the lens convex and cause myopia.

but too much lead will cause lead poisoning. Once it occurs, it will cause various visual dysfunction, mainly including retinal edema, retrobulbar optic neuritis, optic nerve atrophy, eye movement disorder, abnormal pupil regulation, blind spot, abductor paralysis, visual field change, etc.

therefore, we should properly control the intake of lead and eat more foods rich in protein, high in calcium and high in iron; Eat less foods with high lead content, such as Songhua eggs and popcorn. Also pay attention to let children have less contact with low-quality toys, pencils and other items with high lead content.

5. Protein and amino acid: protein is the main component of cells. When it is lacking, vision is very easy to fatigue and eye muscle tension can induce myopia. As far as the sclera is concerned, it can become the tough shell of the eyeball because it contains a variety of essential amino acids to form a very strong fibrous tissue.

animal foods such as meat, fish, eggs and milk are not only rich in protein, but also contain all necessary amino acids.

6. Vitamin A: when lacking, the adaptability of the eyes to the dark environment decreases, that is, it takes a long time to adapt from the bright to the dark, and it is easy to suffer from night blindness in serious cases; At the same time, the eyes will feel dry and astringent, easy to fatigue, etc. in severe cases, the white surface of the eyes will be dry and wrinkled, and even lead to corneal ulcer.

vitamin A exists in animal liver, cod liver oil, milk and eggs, as well as plant foods, such as carrots, amaranth, spinach, leek, green pepper, red heart sweet potato, orange, apricot, persimmon, etc.

7. Vitamin B1: teenagers like sweets. Excessive high sugar diet consumes a lot of vitamin B1 in the metabolism of the body. In particular, the acidic substances produced by sugar metabolism need to neutralize with calcium, chromium and other basic elements in the body, especially with calcium salt, which is reduced in the blood, resulting in the reduction of blood calcium and the bodyThe relative reduction of calcium and chromium in the eye will affect the tenacity of the eye wall, lengthen the eye axis and cause myopia. Therefore, lack of vitamin B1 will aggravate the occurrence and degree of myopia; It will also cause the resistance of the optic nerve system of the eyes to be significantly weakened, and there will be symptoms such as optic neuritis, affecting vision.

and

vitamin B1 are easily dissolved in water. Therefore, when washing spinach vegetables rich in vitamin B1, it is best not to chop them first, and the water should also be controlled during cooking to avoid excessive loss of vitamin B1. Vitamin B1 exists in various green leafy vegetables, bean products, lean meat and various seafood.

8. Vitamin B2: when the human body lacks vitamin B2, it can induce angular stomatitis, stomatitis and eye tissue inflammation. It will also make the eyes covered with blood, afraid of light, easy to cry, etc. Many people have unexplained symptoms such as dry eyes, eyelid inflammation and conjunctivitis at the time of season change, which is the result of temporary metabolic disorder when the human body adapts to season change, resulting in a lack of vitamin B2 in the body.

vitamin B2 has strong acid resistance, but weak alkaline resistance, which is easy to be damaged by alkaline food, so foods containing vitamin B2 cannot be cooked with alkaline food; Vitamin B2 is also easily soluble in water. When cooking, control the water content and don’t let it lose too much.

and

foods rich in vitamin B2 include: milk, milk products, cheese, lean meat, egg yolk, various green vegetables and various seafood.

9. Vitamin E: vitamin E can inhibit the lipid peroxide reaction in the crystalline body of the eye, dilate the terminal blood vessels, improve blood circulation and prevent the occurrence and development of myopia. If vitamin E deficiency can reduce the antioxidant effect of the body, it will also weaken the auxiliary effect of treating cataract, diabetic retinopathy, various choroidal retinopathy and optic atrophy. The content of vitamin E in

and

soybean oil, peanut oil and banana is high.

10. Vitamin C: Vitamin C is one of the components of the eye lens. If you lack vitamin C, you are prone to cataract with cloudy lens.

and

contain a lot of vitamin C foods, including all kinds of fresh vegetables and fruits, among which green pepper, cucumber, cauliflower, Chinese cabbage, fresh jujube, raw pear and orange are the highest.

11. Taurine: if the human body lacks taurine, it is easy to produce eye fatigue. In the long run, it will form low vision.

taurine has high content in squid, shrimp, crab, oyster, shellfish, marine fish and milk.

12. Lutein: lutein is a major element and component of human retinal macula. It belongs to carotenoid and is a natural antioxidant, It has the characteristics of reducing the harm of photooxidation reaction in the macula (including absorbing and removing blue light), so as to protect the retina and lens, prevent visual degradation, reduce and delay the aging of the eyes and the occurrence of cataract. Therefore, if the macula and retina are short of lutein for a long time, it will affect the visual acuity, and even lead to blindness if the symptoms are serious.

Lutein cannot be synthesized artificially, so its sources include spinach, lettuce, green cauliflower, cabbage, celery, okra, egg yolk, carrot, corn, pumpkin, papaya, melon, guava, orange, orange, peach, etc. Zeaxanthin comes from corn, egg yolk, orange, papaya, yellow pepper, medlar, etc.
