Eight external causes of children suffering from myopia?

Abstract: on the contrary, children who learn to walk too early will try to adjust the diopter and focal length of their eyes to focus because they can’t see the distant scenery, which will make their children’s eyes tired and easy to damage their eyesight.

  1. Children who sleep with lights on at night

children who sleep with lights on at night are more likely to develop myopia in the future, especially for children under the age of 2. If the child sleeps in a dark room before the age of 2, the proportion of myopia is 10%; If you sleep in a room with a small night light, the proportion of myopia is 34%; If you sleep in a room with headlights on, the proportion of myopia is 55%.

therefore, children must not turn on the light to sleep at night. If the child is really afraid of the dark, at least don’t turn on the bedroom light, you can turn on the corridor light.

  2. Children who learn to walk early

children who learn to walk too early will not only affect the development of spine, but also have a certain impact on the development of vision. Children’s vision development is not perfect after birth. It is very beneficial to let children practice crawling. On the contrary, children who learn to walk too early will try to adjust the diopter and focal length of their eyes to focus because they can’t see the distant scenery clearly, which will make their children’s eyes tired and easy to damage their eyesight.

  3. Children who often play with electronic products

and

. Many young parents like to “look after their children” with mobile phones and iPads. Once the children get their hands, they will almost immediately calm down and don’t need their parents’ company at all. However, for children whose vision is not yet mature, the damage of electronic products to vision is very great.

when children stare at the electronic screen for a long time, the radiation of light on the screen will inhibit the function of children’s retinal photoreceptor cells, causing visual fatigue and vision loss. At the same time, the screen brightness and sight distance flicker frequently, which will make the ciliary muscles of children’s eyes in a state of frequent movement, When ciliary muscle fatigue is excessive (ciliary muscle spasm), children are prone to myopia. Therefore, in the critical period of children’s visual development, parents should minimize their children’s exposure to electronic products and encourage their children to carry out more outdoor activities to alleviate eye fatigue.

4. Children with unbalanced nutrition

In the period of rapid growth and development of children, if the nutrition is unbalanced, the body may lack some nutrients. When the child lacks the following three nutrients, it may increase the probability of myopia.

and

calcium: calcium is related to the formation of the eyeball. If calcium intake is insufficient, it may lead to the monosexual decline of the sclera, the increase of pressure in the lens, and the elongation of the anterior and posterior diameter of the eyeball, resulting in myopia.

and

calcium rich foods include milk, yogurt, cheese, loach, shrimp, kelp, peanut, sesame paste, tofu, cabbage, rape, laver, fungus, egg yolk, pig liver, cow liver, sheep liver, etc.

and

chromium: if the child lacks chromium in the body, the activity of insulin will decline, and the regulation ability of glucose metabolism will also decline, resulting in too much sugar in the child’s body remaining in the blood, forcing the diopter of the eyes to change, and finally forming myopia.

and

chromium rich foods include beef, black pepper, brown rice, corn, millet, brown sugar, grape juice, edible fungi, etc.

vitamin A: one of the important physiological functions of vitamin A is to maintain the normal function of cornea and retina. The common symptoms of vitamin A deficiency are night blindness and vision loss. Therefore, there must be no lack of vitamin A in the child’s diet.

and

foods rich in vitamin A include spinach, alfalfa, pea seedlings, sweet potato, carrot, green pepper, pumpkin, tomato, pea, celery, lettuce, asparagus, animal liver, milk and dairy products, poultry eggs, etc.

  5. Research on

and

of sugar loving children shows that children who eat sweets for a long time are more likely to develop myopia and progress faster than children with normal diet. Because sugar will soften the sclera of the eyeball, which is an important tissue to wrap the eyeball and maintain the shape of the eyeball. If the sclera becomes soft, the eyeball is easy to deform.

  6. Children who sleep less

and

sleep less is also one of the reasons for children’s myopia. If the child is in a period of rapid growth and development, especially between the ages of 7 and 14, if the child sleeps too little and his eyes are tired for a long time, it is also easy to lead to myopia. During this period of time, if the child is nervous about learning, parents must pay attention to the child’s eye hygiene.

  7. Children with low birth weight, such as

,

, who had less than 2500 grams of birth weight or had 2 weeks premature delivery, had a higher incidence rate of nearsightedness. Congenital development is inherently poor. In addition, if adverse external factors are encountered the day after tomorrow, the development of ocular axis is very easy to be affected. For such children, parents should pay special attention to the acquired living habits and eye hygiene.

  8. Parents’ myopia exceeds 600 degrees, and children are prone to myopia

and

. Generally speaking, parents’ myopia below 300 degrees will not be inherited to children; The probability of inheritance of myopia of 300 ~ 600 degrees will increase; The genetic probability of myopia above 600 degrees will be greater.

the following five situations may be signs of children’s myopia:

1. Squint

when you find that children always squint when reading or watching TV, parents should pay attention. Because when squinting, the eyelid can block part of the pupil to reduce the scattering of light and temporarily improve and improve vision. If it goes on for a long time, it is likely to cause children’s myopia.

2. Frowning

frowning is also a way for children to try to improve their eyesight. Often frowning will make the extraocular muscles compress the eyeball, reverse stimulate the eye muscles and accelerate the formation of myopia. Some children also show behaviors such as pulling the corners of their eyes or rubbing their eyes.

3. Look at things with your head askew

some children will always look at things with their head askew in the early stage of myopia, because looking at things with your head askew can reduce the impact of scattered light on vision and see things more clearly. Therefore, if you find that children always look at things with their heads tilted, you must correct them in time.

  4、Strabismus

when a child has strabismus, it may be that the vision of one eye decreases, and what he sees will inadvertently use the normal eye. Therefore, when children often squint at things, it may be a sign of myopia.

5. Frequent blinking

frequent blinking can alleviate myopia and increase visual acuity to a certain extent. When children can’t see clearly, they may choose to blink constantly to make their eyesight clearer.

and

in addition, we should emphasize with our parents that once you find your child short-sighted, don’t rush to wear glasses for your child. Myopia is divided into true myopia and false myopia. Pseudomyopia is caused by close viewing or improper use of eyes. Because the ciliary muscle has been in a state of tension and spasm, it produces ametropia, resulting in eye fatigue. Generally speaking, most children who have just formed myopia are pseudomyopia. Although pseudomyopia is the prelude to true myopia, the eyeball structure of pseudomyopia has not changed, only the change of physiological function. As long as it is treated in time and pay attention to eye hygiene, it can return to normal.

however, the survey shows that the stage of children’s pseudomyopia is often not valued by their parents. 70% of the surveyed students fail to be treated in time when their eyesight is 0.8 for the first time, and about 15% of them directly wear glasses, so that they directly become true myopia. Therefore, for children with signs of myopia, parents should correct or treat them in time once they find them, so as not to miss the best recovery period.
