I m nearsighted, does vitamin A help?

Vitamin A is mainly night blindness and is mainly absorbed from food. Try not to take medication. There is also a disproportionate amount of vision and power. Some.

A person may have eyes of more than 400 degrees, but unaided vision may reach. Everyone's ability to regulate is different. Now that your power is not very high, there are some ** methods that can be employed now.

For example, you can take off your glasses, focus on one finger with both eyes at the same time, and then move your finger back and forth to strengthen the ability of the ciliary muscle. Do more eye massages. Eat more fish, liver, and cereals.

If you are caused by malnutrition, and it is caused by vitamin A deficiency, then persistence is effective.

But, you didn't cause myopia because of this, did you?!

Pay attention to eye hygiene and eye habits, and pay attention to the comprehensiveness of nutrition. It is recommended to go to a professional eye care institution for physiotherapy.

At 185 Deping Road, Pudong, Shanghai, there is a Vision Protection Center in the Family Family, you can try it. Do not inquire about similar local professional institutions in Shanghai.

Wishing you good health!

It's definitely going to work, but the effect is certainly not going to be very obvious, stick to it...

Keep in mind that the cause of myopia is caused by eye fatigue at close range, which has nothing to do with vitamin A, and low night vision has a certain relationship with vitamin deficiency and cannot be confused. Low-grade myopia, if it affects the ability to see the blackboard clearly, it is still necessary, but it cannot be relied on, it is best to cooperate with effective ** to improve their naked eye vision and control the development of power, please consult for details**.

I think you're asking a little strangely, is this obviously good for the eyes, but it's not good to eat it for a long time??

Forehead... Isn't vitamin A a cure for night blindness? 、、

The benefit of vitamin A for the eyes is to supplement the eyes with nutrients and relieve eye fatigue, and I have a suggestion that you can also eat some carrots or walnuts, which are also rich in vitamin A.

Yes. In the body, vitamin A can be converted into rhodopsin, which is needed by the eye, which is necessary for retinal cells to sense light and produce vision. Therefore, people with severe vitamin A deficiency will not be able to see in the low-light environment at night due to their poor sensitivity to light, which is night blindness, and after supplementing enough vitamin A, dark vision at night will return to normal.

Protecting your eyes is more important than your diet. Because the eyes need the nourishment of tears, which contain a variety of nutrients, the most important of which is vitamin B2; The process of seeing requires the involvement of vitamin A; The conduction of the optic nerve needs the help of vitamin B group; Preventing eye aging requires healthy blood vessels, and vitamins C and E are helpful for this.

Vitamin A is a vitamin that we Chinese are prone to lack. When vitamin A is deficient, the eyes often feel dry and astringent, easy to get tired, and in severe cases, the white surface of the eyes is dry and wrinkled, and even leads to corneal ulcers. Before these symptoms occur, a person's low-light vision has been reduced, and dark adaptation is poor, that is, it is difficult to adapt for a long time from light to dark.

To supplement vitamin A, you should eat more liver, milk, egg yolks, green leafy vegetables, carrots, sweet potatoes, etc.

Lack of vitamin B2 can easily cause inflammation of the horns of the mouth, lips and tongue, and will also make the eyes bloodshot, afraid of light, and prone to tears. To supplement vitamin B2, you should eat more liver, kidney, milk, green leafy vegetables, mushrooms, sweet potatoes, etc.

In addition, taurine has a good effect on relieving low vision and eye strain. Taurine is found in higher levels in aquatic animals such as squid, shrimp, crabs, oysters, shellfish, marine fish and milk.

Vitamin A and carotene help to nourish the liver and eyes, and relieve eye fatigue. Vitamin A is mainly found in the liver, cod liver oil, and egg yolk of various animals, and plant foods can only provide provitamin A. - Carotene is mainly found in fruits and vegetables such as carrots, tomatoes, and spinach.

Vitamin C is also great for the eyes. The amount of vitamin C in the human eye is several times higher than in the blood. With age, vitamin C levels decrease significantly, and the lens becomes dystrophied, which can cause lens degeneration over time.

Therefore, eat more vegetables and fruits rich in vitamin C.

Carrots are rich in sucrose, glucose, starch, etc., among which the content of provitamin A is the largest, and its effect is similar to that of cod liver oil. In addition, carrots are also rich in carotene, which can maintain the health of the eyes and **.

Spinach contains protein, fat, carbohydrates, crude fiber, calcium, phosphorus, iron, carotene, riboflavin, etc., it is not only a vegetable with high nutritional value, but also a good product for eye protection.

Other eye-catching foods: tomatoes, leeks, wolfberries, green peppers, apricots, dates, sweet potatoes.

If a computer operator works too long in front of a phosphor screen, the rhodopsin on the retina, which is mainly synthesized from vitamin A, is depleted. Therefore, computer operators should eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat and other foods to supplement vitamin A and protein in the human body. Drinking more tea, tea polyphenols and other active substances in tea will be conducive to the absorption and resistance of radioactive substances.

There are benefits that can alleviate eye strain.

People with myopia should be properly supplemented with calcium, zinc, chromium, etc.

Calcium: Calcium is the main building block of bones and the main building blocks of the sclera. The higher content of calcium plays a major role in enhancing the toughness of the sclera.

Animal bones such as cow bones, pig bones, and sheep bones are rich in calcium and are easily absorbed and utilized by the human body. Others, such as milk, beans, shrimp skin, dried shrimp, eggs, rape, cabbage, peanuts, jujubes, etc., also contain more calcium.

Protein: In the case of the sclera, it can be the tough shell of the eyeball, because it contains a variety of essential amino acids, which make up the strong fibrous tissue. Although the sclera has a certain degree of toughness, it is still relatively weak in the anterior and posterior diameter of the axle.

Animal foods such as meat, fish, eggs, and milk are not only rich in protein, but also contain all essential amino acids, so people with myopia can appropriately supplement such foods.

Zinc and chromium: Zinc and chromium are generally deficient in patients with myopia, and people with myopia should eat more foods that contain more zinc and chromium. Foods such as soybeans, almonds, seaweed, kelp, mutton, yellow croaker, tea, meat, beef, liver, etc., contain more zinc and chromium, which can be increased moderately.

Vitamins: Dietary therapy**When myopia, vitamin A, vitamin B1, vitamin B2, vitamin C and vitamin E should be appropriately supplemented. Vitamin-rich foods include eggs, milk, meat, fish, liver, and fresh vegetables and fruits.

Vitamin A, carotene, pay attention to the liver, because 95% of vitamin A is stored in the liver, but also pay attention to the replenishment of minerals (Ca, Se, Cr) and protein; If you want to see clearly, you can also eat tuna oil, which contains DHA, or lutein can also relieve visual fatigue, and it is also effective to eat more blueberries ......

Vitamin A has the effect of maintaining the normal cornea of the eye, preventing the cornea from drying out and degenerating, and enhancing the ability to see in the absence of light. If there is a lack of vitamin A in the human body, it will affect the synthesis rate of rhodopsin, and it will not be able to see clearly in the dark field, resulting in night blindness. Lack of vitamin A can also damage the tissue of lacrimal gland epithelial cells, reduce secretion, and cause dry eye disease.

Vitamin A is a fat-soluble vitamin, so in order to improve its utilization, cooking methods such as frying, frying, and frying should be used.

Effects of vitamin A deficiency on the eyes:

1. Dark adaptability decreases, and night blindness gradually develops.

2. The epithelium of the horn and conjunctiva will dry and fall off, and in severe cases, it will soften and perforate and lead to blindness.

3. Decreased tear gland secretion, resulting in dry eye syndrome.

Vitamin A is a water-soluble vitamin, which is relatively stable to heat, acid and alkali, but is easily oxidized, such as ultraviolet rays can promote its oxidative damage. Vitamin A is abundant in animal liver, egg yolks, milk powder, as well as red-yellow and dark green vegetables and fruits. Therefore, if you eat more of these things, you can maintain enough vitamin A.

Once vitamin A deficiency occurs, the symptoms and signs of the eye mentioned above will appear. Therefore, we must have a balanced diet in life, don't be picky eaters, and eat a little bit of everything, so as not to lead to vitamin deficiency, especially vitamin A deficiency.

Vitamin A, if you lack this nutrient, you will develop night blindness, your eyes will feel dry at night, and the body's resistance will also decrease for a period of time. Vitamin A deficiency can affect the eyesight and make it difficult to see clearly in the dark field, resulting in night blindness. Vitamin A deficiency reduces secretion and can also cause dry eye disease. Wait.

Vitamin A increases the formation of photosensitive pigments in the eye, and if vitamin A is deficient, the tear glands can become blocked, making the cornea keratin or dry. Many fruits and vegetables contain nutrients that can protect and relieve dry eyes.

Vitamin A is one that improves your dark vision.

It is the ability to see things in a darker part of the night.
