Core Tip: In addition to being a natural factor, children's myopia is caused by poor living factors. Parents need to have a good understanding of this and avoid children becoming myopia.

Many children wear glasses when they are young, which makes many parents feel very worried. In fact, in addition to being a natural factor, children's myopia is caused by poor living factors. Parents need to have a good understanding of this and avoid children becoming myopia.

The reasons for myopia in children include the following:

First, look too close when there are too many

In the city, people's sights are mostly within 5 meters. You can't explain to the children what the horizon is because you can't see them at all! It is precisely because the city has a wide field of vision and lacks an environment that can provide children with a far-sighted vision. It does not require hyperopia, so his farsightedness will become weaker and weaker.

Second, too little outdoor activities

The living space is too small now. The child is active indoors most of the time. There are many eyes in close-up use, and the child's eye adaptability is very strong. It will adjust to adapt to this close distance. Moreover, when there is more in the house, the chances of watching TV and playing computer will increase. If you don't pay attention to distance and posture, it is easy to make your eyes fatigued.

Outdoors, how close the object is, it is farther than the house. Studies have shown that children who are often exercising outdoors are less likely to suffer from myopia than those who do not.

Third, the light is not strong

"Is the lighting enough? I am worried that the light will be too dark to affect the child's vision." We generally think so. In fact, ophthalmologists believe that the light of children reading and writing is not too dark, but too bright! Excessive light can make your child's eyes feel tired easily. The child needs soft light, and the light is guaranteed to come from the left front of the child. Therefore, when children read and write at night, they can choose the light that can adjust the brightness and brightness, and adjust the brightness to soft.

Fourth, the glasses are too casual

The optometry of the ciliary muscle is to let the ciliary muscles of the child's eyes be completely relaxed, so as to find out the cause of the child's poor eyesight, whether it is true myopia or pseudomyopia, whether it is farsightedness or astigmatism. Regular dilated optometry takes a week to resume free reading. Urgent parents often choose a quick dip.

However, when the child is rapidly dilated, the child's ciliary muscles are only in a state of insufficient paralysis, and they are not completely relaxed. At this time, the results obtained by the examination are not accurate, and the child may be equipped with myopia glasses that are higher than the actual degree. In this way, the child's myopia will develop to a deeper degree.

Fifth, the book paper, printing is too "pay attention"

More and more beautifully printed and more and more elegant papers make children's books more and more enjoyable. However, these beautiful books may also hurt the child's eyes. The coated paper is too reflective, especially at night, and it squints. This dazzling light is called glare in medicine, it makes things you want to see more unclear, and the eyes are more prone to fatigue.
