Data show that in 2018, the overall myopia rate of children and adolescents in Beijing was 57.3%, higher than the national myopia rate.

The third grade of primary school is the high incidence of "wearing kids eyeglasses online". "When I entered the school in the first grade, the number of small glasses was in the single digits, but by the third grade, the detection rate of poor vision was about 25 percent." Wu Jian, principal of Hezhima Hutong Primary School in Dongcheng District of Beijing, said that the school is very concerned about vision problems, and began to carry out vision management for all students in 2016. In recent years, the average annual myopia rate has dropped by 1%, and it is currently at a low level in the city.

Wu Jian introduced that after the school checks the students' eyesight every semester, and finds that there are more cases of vision loss, it will communicate with parents in time, ensure outdoor exercise time and eye health exercises twice a day, and help children understand the importance of vision with vivid forms such as "clapping nursery rhymes".

"In 2018, our school had a 'yellow' warning level for vision-related tests in the district, slightly better than red, but not as good as green." Guo Jingui, executive principal of Zhongguancun No. 3 Primary School in Beijing's Haidian District, said the myopia rate reached 57.5 percent at that time. After more than two years of efforts to overcome the adverse factors brought about by the epidemic, the myopia rate has dropped to about 48.5%.

The experience of the prevention and control of myopia in the three children of Zhongguancun began to cultivate the habit of using the eye from the first grade, and formed the idea of using the eye by holding a pen and reading a book "one punch, one foot, one inch". On the other hand, the school attaches special importance to sports activities, and has introduced measures such as lengthening the number of physical education hours, extending the recess exercise time, and using the playground off-peak, so that children can "get wild" on the playground, which not only improves their physical fitness, but also effectively improves the eye environment.

"Wearing glasses in the third grade is not caused by studying too hard in the first and second grade, but has a lot to do with the eye habits of preschool students." Li Li said, we advocate preschool do not use the eyes too early close, there should be some "far-sighted reserve", if the eight-year-old child has 100 degrees of far-sighted reserve, the probability of myopia will be reduced in the rapid growth and development period.
