Many parents are very concerned about how their children can develop less or no myopia through the right diet when they visit the clinic. Modern medical research shows that there is indeed a very close relationship between vitamins and trace elements and the occurrence of eye diseases and good or bad eyesight. Proper supplementation of the nutrients needed by the eyes is very important to protect the eyes, prevent vision damage, prevent eye diseases and improve vision. To prevent the appearance of myopia, in addition to avoid eye fatigue, develop good eye habits, but also pay attention to the dietary balance, in addition to supplement some trace elements and vitamins, often eat some food beneficial to the eyes. Let’s learn more about it.
1, vitamin A, also known as retinol, plays an important role in the formation of human vision. It is involved in the synthesis of retinol in the retina. If vitamin A is insufficient, the eyes’ ability to adapt to the dark environment will be diminished, which may lead to night blindness in severe cases. Vitamin A and beta-carotene help to tonify the liver and brighten the eyes and relieve eye fatigue. Vitamin A is mainly found in the liver of various animals, cod liver oil, egg yolk, and plant foods can only provide vitamin A. Beta-carotene is mainly found in carrots, tomatoes, spinach and other fruits and vegetables. Eat more nuts and foods rich in calcium, protein and vitamin A.
Eat less candy and high-sugar foods. Too much sugar will cause a decrease in blood calcium, which will affect the toughness of the eye wall, making the eye axis longer and contributing to the development of myopia.
2, eat more calcium-rich diet. Calcium is the “protector” of the eye tissue. The lack of calcium in the body not only causes the retina of the eye to lose elasticity, the lens pressure rises, the front and rear diameter of the eye elongates, but also causes degenerative lesions in the cornea and ciliary muscle, which can easily cause vision loss or myopia. Dairy, beans, mushrooms, dried fruits and seafood are rich in calcium, and vitamin D with food, which is conducive to the absorption of calcium.
3, in addition, medical research shows that myopia and the lack of trace elements selenium related. Trace elements selenium, zinc and chromium can improve the function of eye tissue and prevent vision loss. Foods containing more selenium are animal liver, eggs, fish, shellfish, soybeans, mushrooms, asparagus, capers, carrots, etc.; Finally, eat more coarse grains and fresh vegetables, and eat less candy and sweets. Fresh vegetables in the vitamin B, vitamin C, vitamin E has a protective effect on the eyes.
4.Chinese medical treatment
First, chrysanthemum is very effective in treating dry eyes, fatigue and blurred vision. China has known since ancient times that chrysanthemum has the effect of nourishing and protecting the eyes. In addition to applying chrysanthemum water to the eyes, you may want to make some chrysanthemum tea and drink it regularly. If you can drink three or four cups of chrysanthemum tea every day, you can not only make the symptoms of eye fatigue disappear, but also help to restore your eyesight. Chrysanthemum flowers should be selected small and ugly flowers and yellow color, drinking chrysanthemum tea is best not to add another tea, only the dried chrysanthemum flowers in water or boiled to drink it.

Cooking method: the above three flavors in the right amount, add water to make tea, longan kernel does not need to be broken.
Dosage: just as a general tea to drink, drink every day, at least six months in a row.

In autumn and winter, the phenomenon of dry eyes of office workers increases significantly. Feeling dry and tired eyes, the first reaction of many people is to take a drop of eye drops, but do not know that this random practice of dropping eye drops, is likely to cause more damage to the eyes.
Although the name of eye drops is drops, but most people are used to using it as a health care product, uncomfortable point a little, point after feeling comfortable, it is considered good. In fact, eye drops are divided into different types. The public in the drugstore common eye drops, according to the role of two types of general, respectively, lubricating and vasoconstrictor type.
Lubricating eye drops mainly play a role in relieving the supplemental eye fluid and relieving visual fatigue; constricting vascular eye drops are usually used to deal with intraocular blood, after people use their eyes excessively, they often find that the eyes are covered with blood, which is a manifestation of conjunctival congestion, the effect of such eye drops is more significant at this time.
Lubricating eye drops mainly play a role in relieving the liquid in the eyes and relieving visual fatigue; constricting vascular eye drops are usually used to deal with intraocular blood, after people use their eyes excessively, they often find that the eyes are covered with blood, which is a manifestation of conjunctival congestion, and the effect of using such eye drops is more significant at this time.
Side effects of eye drops
Some people feel their eyes are fresh after using vasoconstrictive eye drops, and the red blood will soon disappear, but these eye drops are used to constrict blood vessels by drug means, and if you stop using them occasionally, the effect is likely to rebound and your eyes become more red. In this special reminder, some people suffering from cardiovascular disease, be especially careful with constrictive eye drops, because it is likely to lead to an increase in blood pressure, which is very harmful.
Lubricated eye drops have relatively fewer side effects and fewer contraindications, but those with more than 1ml usually contain a certain amount of preservatives, which may cause some damage to the corneal epithelial cells if used excessively.
How can I tell the type of eye drops?
The eye drops that patients see in ordinary pharmacies are often difficult to tell whether they belong to the lubricating type or the vasoconstrictor type by the description on them. Patients can distinguish by looking at the ingredients on the back of the box: those containing cellulose, vinyl alcohol and other ingredients are usually lubricant-type eye drops, and the main ingredient of vasoconstrictor-type eye drops is usually naphthazoline.
It is also worth noting that “myopic patients who have the habit of wearing contact lenses must try to avoid using eye drops containing preservatives, most preservatives will be absorbed within the lens and cause damage to the cornea with long-term use, and it is recommended that contact lens wearers try to use eye drops without preservatives.”
Too many eye drops can cause dry eye syndrome
There are some patients, due to eye disorders such as glaucoma, cataract, uveitis or wrongly diagnosed as conjunctivitis due to eye discomfort, long-term use of eye drops too often, too much, too many types, too long, destroying the normal physiological function of tears, artificially caused or aggravated dry eye symptoms.
Preservative eye drops should be used up within two weeks The ingredient in eye drops that is not good for the eyes is preservatives, which can irritate the eyes, and prolonged drops of eye drops containing preservatives can cause conjunctival and corneal damage. Therefore, eye drops containing preservatives should not be used for a long time.
Hormonal eye drops should be used with caution
Four to five percent of the normal population is sensitive to hormones, which means that four to five out of a hundred people who use hormonal eye drops for a long time may suffer from hormonal glaucoma. Some high-risk groups are generally sensitive to hormones and need special attention when using corticosteroids.
