Children’s myopia must be corrected, but also beware of improper correction!

Abstract: once myopia really occurs, there is no way to restore the emmetropic refractive state except surgery at this stage, and we should pay more attention to the complications caused by the development of high myopia. In order to ensure the quality of vision and life, myopia prevention should precede treatment., What is the reason for myopia prevention and control?, In fact, the voice of myopia prevention and control has been repeatedly raised in recent years, but the myopia rate of students in our country is still high, and the total number of myopia is even the first in the world. Why?, Experts pointed out that based on the existing research, the occurrence and development of myopia are mainly influenced by genetic and environmental factors., Genetic factors, simply speaking, if parents have high myopia, the probability of high myopia of children will be 8-12 times higher than that of normal people, and children may have myopia when they are very young; A study of twins shows that one of the twins has myopia, and the other often has myopia, and the degree is not much different;, Environmental factors are more critical than genetic factors. At present, there are three main and exact reasons: 1. Optical defocus. For example, Children in the process of eye development (usually before the age of 18), if myopia is not corrected or corrected incorrectly, it will produce optical defocus and aggravate myopia. A typical case is overcorrection. After light is focused on the retina, it can aggravate myopia; 2. Form deprivation. Animal experiments have proved that myopia occurs when the eyes can’t see or see clearly. Some children Born with congenital cataract, ptosis of upper eyelids, unable to open and see, the possibility of myopia is also higher. Overcorrection of myopia will aggravate the occurrence of myopia. Similarly, when undercorrected or uncorrected, the form deprivation effect will also deepen children’s myopia;,

myopia prevention and control “more prevention and control”, why?

genetic factors. In short, if parents have high myopia, the probability of children’s high myopia will be 8-12 times higher than that of normal people, and children may have myopia when they are very young; A twin study shows that one of the twins has myopia, and the other often has myopia, and the degree is not much different;

and environmental factors are more critical than genetic factors. At present, there are three more and more accurate reasons:

1. Optical defocus. For example, In the process of eye development (usually before the age of 18), if a child has myopia and does not correct or correct the correction, it will produce optical defocus and aggravate myopia. A typical case is overcorrection. After the light is focused on the retina, it can aggravate myopia;

2. Form deprivation. Animal experiments have proved that myopia occurs when the eyes can’t see or see clearly. Some children are born with congenital cataract, ptosis of upper eyelids, unable to open their eyes and see, and the possibility of myopia is also higher. Overcorrected myopia will aggravate the occurrence of myopia. Similarly, when undercorrected or uncorrected, the form deprivation effect will also deepen children’s myopia;

3. Sunlight and outdoor sports. Asia is actually a “disaster area” of myopia. We are concerned that the incidence of myopia among children in North America, Europe and other places is low, mainly due to outdoor sports. Studies have proved that the myopia rate of children who spend more than three hours outdoors a day has decreased significantly, and natural light is the key influencing factor. Professor Zhong Xingwu of

and

stressed that indoor sports can not prevent myopia. Now children have heavy schoolwork and may not be able to guarantee 2-3 hours of outdoor time. Outdoor sports in different periods are also effective in controlling myopia. Parents should remind children to go outdoors after homework. In addition, too much outdoor light intensity will also cause eye damage. Pay attention to this and take protective measures.

myopia develops into a morbid condition. How to comprehensively prevent and control it?

what we need to know is that once myopia really occurs, there is no way to restore the refractive state of emmetropia at this stage except surgery, and we should pay more attention to the occurrence of complications caused by the development of high myopia. In order to ensure visual quality and quality of life, myopia prevention should precede treatment. Professor Zhong Xingwu mentioned comprehensive myopia prevention and control, pointing out that it is precisely because there is no best way to prevent and control myopia, “the occurrence and development of myopia is a comprehensive multi factor process, so comprehensive prevention and control methods are also needed.”

according to our current ability level, Professor Zhong Xingwu puts forward the following suggestions:

1 Carry out medical optometry and glasses to correctly deal with ametropia such as myopia, hyperopia and astigmatism. In terms of medical means, we should first find out whether the child is really short-sighted and what is the degree of myopia? Is there astigmatism? Or hyperopia? On this basis, scientific correction is carried out to avoid the effects of optical defocus and form deprivation; In addition, not all kinds of ametropia need to be corrected, such as children’s physiological hyperopia;

  2. Pay attention to the role of outdoor sports in the prevention and control of myopia. Parents and teachers must not ignore their children’s ten minutes between classes and outdoor activities after class, and strive for these valuable time for myopia prevention and control;

  3. For the rapid development of myopia, doctors and parents should face it squarely and slow down the development of myopia through some methods to control myopia, such as corneal shaping mirror;

  4. At present, there is no direct evidence to prove that some physical methods of massage and eye health care are effective. It is suggested that they can be carried out appropriately without damage to the structure and function of the eyeball, but their own operation should avoid directly touching the eyeball as far as possible; Some bad eye habits, such as reading while lying down, working under the condition of too weak and unstable light, and seeing objects, may also produce form deprivation, which should be avoided as far as possible.

in addition, parents should pay attention to avoid falling into misunderstandings in the process of children’s matching glasses: children
