How to prevent myopia 10, how to prevent myopia?

Myopia prevention refers to a method to prevent myopia by correcting posture and shortening the time. The incidence of myopia in China is still increasing day by day, and medical experts believe that the visual environment is the main cause of myopia, rather than eye habits.

The essence of myopia is that the regulatory function of the eye muscles declines, resulting in distant light passing through the refractive of the eye, and the focus falls in front of the retina, and a clear image cannot be formed on the retina. It can be seen that in order to prevent myopia, it is necessary to avoid excessive tension of the eye muscles, which leads to the decline of their regulatory function.

What should parents do if they find that their children are suffering from myopia?The best way to help your child's eyesight is to get outdoors. Foreign research experiments have shown that children who spend 3 hours outdoors a day have a much lower rate of myopia or myopia progression than children who spend 1 hour outdoors.

Nowadays, children are more often indoors, whether it is playing or doing homework, which is undoubtedly one of the reasons for the low age of myopia. ”.The theory that outdoor activities are beneficial to vision health has long appeared in textbooks, but with the rise of myopia worldwide in recent years, more and more studies and experimental observations have confirmed this theory.

Outdoor activities can not only expose more sunlight, but also promote the secretion of dopamine, which can block the growth of the eye axis and reduce the risk of rapid eye development; In addition, ultraviolet rays can also increase the synthesis of vitamin D in the body, stiffen the sclera, and also help slow down the growth of the eye axis. In addition, a wider field of view is also beneficial for the development of the eyeball

Teach you simple ways to prevent myopia

The professor at Harvard University tells you: to prevent myopia in children, you only need to do one thing. It's that simple, can you stick to it?

A few suggestions for you:

1. Develop good eye habits, maintain a correct posture when reading and writing, keep a distance of about 30cm between your eyes and books, and do not read books while walking, riding in a car or lying in bed.

2. The lighting of the learning and working environment should be moderate, the lighting should be free of glare or flickering, the blackboard should not be reflective, and it should not be read or written in sunlight or dark light.

3. Check your eyesight regularly, and wear appropriate glasses for myopia diagnosed by optometry to maintain good vision and normal adjustment and collection.

4. Strengthen physical exercise, pay attention to nutrition, and enhance physical fitness.

How to prevent myopia.

1) Pay attention to environmental factors: the classroom should be bright, the desktop and blackboard should not reflect too strongly, there should be windows on the left and right sides, not too high or too small, so that you can see the window from any position in the classroom, and change the seat regularly; The child's desk at home should be placed in front of the window without obstruction outside, the desk lamp should be placed in front of the left, and the light should be soft, such as an incandescent lamp, it is best to be between 25 and 40w, and the position should not directly irradiate the eyes; It is best to have a TV at least 3m away from your eyes.

2) Change the way of play: modern urban children's games are mostly based on indoor self-entertainment, such as personal toys, game consoles, computers, televisions, etc., and it is rare for children to spontaneously play outdoor collective games, such as hide and seek, castle attack, etc., so that children can hardly leave home in a pitiful little spare time, and rarely have the opportunity to get out of the near environment every day. For this reason, parents and teachers should encourage children to change their play patterns and do more outdoor activities.

3) Reform the education system: eye development generally stops before the age of 18 or 20, myopia is a period of rapid development from 12 to 18 years old, and due to the problems of the education system, this period is the period of the heaviest learning pressure, the busiest homework, and the most homework, so that teenagers have significantly reduced outdoor activities and have been in a state of myopia for a long time. To this end, it is necessary to reform the education system and reduce the burden of learning, even from the perspective of ophthalmology.

4) Pay attention to eye hygiene: Teenagers should be educated to pay attention to eye hygiene, pay attention to the distance between their eyes and books when reading, and have a correct posture, and cannot lie down to read or read while walking; Pay attention to the lighting of reading should be sufficient, read and write for 40 consecutive minutes should rest, look away, and not indulge too much in game consoles and TV.

5) Pay attention to eye care: insist on doing eye exercises and lens exercises every day (rhythmically and quickly alternating between looking far and near); Self-acupressure massage (eye ming, bamboo saving, fish waist, silk bamboo empty, Cheng weeping, four white, etc.); Fog vision** (wear + glasses to see far).

6) Vision loss should be checked in the hospital in time. In addition, attention should also be paid to dietary habits and nutritional combinations to avoid deficiency of trace elements such as chromium and calcium. From the perspective of eugenics, when choosing a mate, we should also try to avoid the situation that close relatives and both of them are highly myopia.

To prevent myopia, we must pay attention to the adjustment of diet, otherwise it will appear prematurely, so what do we need to do in our daily diet? The main points are as follows:

1.Eating less sugar, carbohydrate foods or overcooking protein foods will reduce the occurrence of myopia. Eating too much sugar can reduce the amount of trace element chromium in the body.

2. Intake of too much boiled protein food can cause abnormal calcium metabolism in the body, resulting in calcium deficiency. Chromium and calcium directly affect the body's adjustment of intraocular hydraulics, if the human body chromium and calcium content is in a normal balance state, intraocular hydraulics can remain normal, so as to prevent myopia.

3. Pay attention to supplementing the trace elements chromium and calcium in the body. Foods rich in chromium are: beans, wheat, eggs, chicken, pork, butter. Foods rich in chromium and calcium can be reasonably added to the daily diet to achieve the purpose of preventing myopia through dietary regulation.
