Expert: Prevention starting from a certain degree of remote reserves from a certain degree of childhood

Xinhua News Agency, Beijing, June 29 (Reporter Li Heng) Recently, the State Council's report on children's health promotion work shows that the overall myopia rate of children and adolescents in my country is still high. Since the occurrence of new crown pneumonia, children's home and Internet courses have increased, and sports have decreased. Exposure time in front of electronic screens has lengthened, which has led to myopia increases for more children and adolescents. Experts said that preventing myopia began from a certain degree of hyperopia reserve from a childhood.

"Vision is gradually developing with the development of the refractive system and retinal development. The age of 0-6 is the critical period for children's vision development and the fastest stage of eye refractive changes." Li Li introduced that the newborn's eyeballs and a short eye axis, at this time, the eyes are in a long -aversion state. With the growth and development of children, the eyeballs gradually grow up, the eye axis becomes longer, and the degree of consequences gradually decreases and tends to face up. This process is called "the process of righteousness".

Li Li explained that the ideal situation was that children developed from the end of the eyes until the age of 12. Most of the hyperopia before viewing is physiological hyperopia. It is a "remote reserve", which can be understood as a "buffer zone" for "confrontation" vision development.

"The real hyperopia reserves need to be measured accurately after the pupils." Yao Yufeng, an expert at the National Health Popular Science Expert Library and the chief physician of Shao Yifu Hospital affiliated to Zhejiang University Medical College, said that the insufficient reserve reserves refer to the naked eye vision, and the pupils were flexed after the optical test. Although the state of light does not meet myopic standards, the degree of remoteness is lower than the physiological value range of the corresponding age group. The reference reserve is a normal distribution in the overall population. There are no absolute standards. The reference value of reference references at different ages is also different.

Experts say that if children's hyperopia reserves are lower than the value of the corresponding age group, it means that its hyperopia reserves are consumed too much, and myopia may occur earlier. A certain degree of hyperopia reserves are reasonable, but the more the hyperopia reserve is not as good as possible. Excessive hyperopia reserves are more likely to become pathological contempt, which affects the normal development of children's vision function.

"The hyperopia reserve is like a fixed reserve in the bank account opened by a child when he was born, and this reserve is a fixed amount, which will only be consumed without value -added." Yao Yufeng said that with a long time and close -up, the eye uses the eye for a long time with the eye. The lack of outdoor activities, imbalanced diet, etc. are all bad living habits of excessive consumption of remote reserves.

Experts suggested that preserving the reserves of hyperopia requires children, families, and schools to work together to cultivate and urge children to develop good use of eye hygiene habits to establish correct eye -eye care behaviors. For example, standardize reading and writing posture, pay attention to eye time, do good eye exercises, strengthen physical exercise, and screen vision regularly.
