What causes myopia in children? With the popularity of electronic products, the group of people with myopia are getting younger and younger, and more and more people are suffering from myopia. Children can also develop myopia. I believe that you will often see some primary school students wearing glasses in your life. In addition to excessive study pressure, there are other reasons that may cause myopia in children. Let’s share what causes myopia in children and related information. What causes myopia in children 1

First, the eyes are used for too long. Many children have the habit of watching TV or computers for a long time, which can easily cause eye fatigue, damage normal eye vision, and cause eye damage in the long run.

Second, excessive intake of sweets. After eating too much sweets, the calcium content in the body will be reduced, resulting in a decrease in retinal elasticity. In this case, it will also lead to deepening of the eyesight.

Third, the impact of noise. Long-term exposure to a noisy environment will reduce the sensitivity of the eyes to light, which will not only cause vision loss, but also cause a weakening of one's own color vision.

Fourth, the influence of light. Eyes may be damaged by environmental factors in life, such as too bright walls, too dark light, uneven blackboard reflection, etc. These factors will silently affect children's normal vision.

Fifth, poor sitting posture. When reading and writing, if you do not pay attention to the correct sitting posture or the height of the desk and chair is inappropriate, it will cause damage to the eyes.

Sixth, lack of sleep. Long-term lack of sleep will lead to autonomic nerve dysfunction in the body, thereby affecting the sympathetic nerves in the eyes, and ultimately ciliary muscle regulation dysfunction, affecting normal vision.

Seventh, excessive pressure. Today's children continue to attend various study classes and tutoring classes every day. They are under long-term excessive psychological pressure and study pressure, which will also aggravate the problem of myopia.

Eighth, family inheritance. Myopia is also hereditary to a certain extent, especially if both parents have high myopia, then the child has a certain chance of developing myopia.

Ninth, family influence. If the relationship between the husband and wife is not harmonious, or the relationship with the children is tense, it will also cause visual impairment in children. If it is not improved for a long time, it will affect the normal vision of the child.

You will find that more and more children will have myopia problems in life. In addition to using their eyes for a long time, it is more due to some bad living habits and caused by living environment. Parents must pay more attention to their children's physical and mental state, communicate with them in a timely manner, and avoid adverse factors affecting their children's visual development.

Myopia in children is an eye disease caused by a combination of factors. Its formation is often related to the following factors:

1. The eyes are too close. Children with myopia and long-term reading and studying, incorrect sitting posture, eyes too close to the book, causing visual fatigue, abnormal retinal development, and corneal refractive changes can easily form myopia.

2. Use your eyes for too long. If a child's schoolwork is heavy, sometimes parents will arrange additional tutoring classes, or make-up classes to make up for homework, etc. Studying at your desk for long periods of time can cause excessive fatigue to the optic nerve and affect eye health. In particular, children whose eyes are in the developmental stage, are overtired, and use their eyes for a long time are prone to myopia.

3. Influence of genetic factors. Myopia is hereditary to a certain extent and is often dominantly inherited. If parents have myopia and have a high degree of myopia, the probability of inheriting myopia to their children is greater.

4. Causes of malnutrition. If a child is malnourished, zinc-deficient, calcium-deficient, and is often picky or picky about food, it will also affect the normal development of the optic nerve and other tissues of the eye, so he may suffer from low vision and myopia. What causes myopia in children 2

First of all, myopia is generally caused by improper use of eyes. The most prominent symptom of myopia is reduced distance vision, normal near vision, and unclear vision of distant things.

If myopia is not treated correctly and in time, it can easily turn into high myopia, which will have a great impact on daily life, so myopia needs to be paid attention to.

Next, let’s talk about the eight causes of myopia.

First, children who are often exposed to electronic products often have their eyes exposed to high-frequency flashing visual targets, which can cause eye fatigue.

Secondly, children and teachers now use projectors in class, and the impact of this is exactly the same as the above-mentioned modern technology products.

Third, the safety of today’s children’s eating environment is also very important. Pesticide residues in food can cause poisoning and damage vision.

Fourth, genetic factors also account for a large part of the reason. High myopia has a certain family genetic tendency.

Fifth, as children continue to increase their homework, the frequency and time of adjusting and focusing their eyes gradually increase, leading to vision degradation.

Sixth, using your eyes for too long can cause eye fatigue. Turning off the lights and playing with mobile phones at night can easily cause eye fatigue and myopia due to excessive light.

Seventh, teenagers staying up late playing with mobile phones will accelerate the deterioration of their eyesight.

Eighth, not paying attention to visual hygiene can easily lead to myopia.

The above eight points are about the causes of myopia. Parents can formulate more correct policies based on these eight points to prevent their children from worsening myopia. Teenagers are most likely to develop myopia, so in daily life, they should pay attention to eye cleaning, do not study in too dark or too bright environments, and eat more foods that can improve eyesight.

1. Incorrect sitting posture, which is very harmful to the child's vision. The child himself is still young, and his self-control ability is much worse than that of adults. When reading and writing, Sitting in your favorite posture, not maintaining the correct posture, sitting too close to books, and without parental supervision will lead to myopia over time.

2. They spend too much time indoors and spend less time outdoors. With the increasing popularity of electronic products, many children watch TV or play computer games for a long time, and parents are busy with their own affairs. Pay attention in time, as this will cause eye fatigue and have a great adverse impact on vision.

3. Uncomfortable living environment. For example, the blackboard in the classroom may reflect unevenly and the light is too dark or too bright. There are also many children who like to read before going to bed at night. Maybe the lighting in the bedroom It is also inappropriate, and it will damage your eyesight invisibly.

The above are some common causes of myopia in children. I hope that the above description can serve as a warning to more parents and friends, so that they can care about their children's vision and worship while they are busy at work. Take your children to play outdoors and exercise more every day.

This can not only improve the body’s immunity, but also reduce the time children spend playing electronic products. It can effectively relieve eye fatigue and protect eyesight. It is also necessary to prepare suitable study tables and chairs and supervision for children at home. The sitting posture of children when studying can reduce the chance of myopia as much as possible.
