In recent years, the rate of myopia in children and adolescents in my country has remained high and rising, and myopia has become increasingly younger and more severe. The comprehensive prevention and control of myopia in children and adolescents is a systematic project, a "tough battle" and a "protracted battle", requiring the joint efforts of the government, schools, medical and health institutions, families, and students.

"Videos" increase, movement decreases

More and more "small glasses"

“I often squint my eyes to see things, frequently blink, rub my eyes, frown, pull the corners of my eyes, and often tilt my head to look at objects... If the child has such a behavior, parents should take the child to the hospital for examination as soon as possible.” Soon after school starts in September , 130,000 elementary and middle school students in Xicheng District, Beijing received a booklet-"Workbook on Prevention and Control of Myopia for Students in Xicheng District."

During the prevention and control of the new crown pneumonia epidemic, large-scale online education and teaching have been carried out in universities, middle schools and primary schools across the country. This effectively compensates for the failure of normal school teaching, and inevitably increases the time of children and adolescents in front of electronic screens. After more than half a year, what changes have happened to the children's eyesight?

“The Ministry of Education has conducted investigations on the vision changes of primary, middle and high school students in 9 provinces, regions and municipalities during the epidemic, and the results of the investigation are not optimistic.” The head of the national comprehensive prevention and control of myopia experts in children and adolescents, the Ministry of Education, Health and Sports According to Wang Dengfeng, the director of the Department of Art Education, the incidence of poor eyesight among the surveyed students has risen from 59.2% to 70.6% in the past six months. Among them, the incidence of poor eyesight in primary school students is 61.6%, that of junior high school students is 80.3%, and the rate of high school students is poor vision. It was 89.3%.

The survey results show that on the one hand, there are more and more new "small glasses"; on the other hand, the degree of myopia students has also increased. 13.2% of students have worsening myopia and high myopia (myopia is higher than 600 degrees). ) The rate rose from 8.9% to 9.1%.

The longer the electronic product is used, the greater the possibility of myopia. During the home study period, the length of online classes increased significantly. According to the survey, before the epidemic, most of the students' online classes were to study in off-campus training institutions. During the epidemic prevention and control period, 80% of students took online classes every day, and 47.9% had online classes more than 2.5 hours a day.

Moreover, watching the "video" time of an electronic screen is more than just learning. Not going out for activities, many children and adolescents can not do without the large and small "screens" in their entertainment time and even their daily lives. According to the survey, during the epidemic prevention and control period, children and adolescents’ time spent playing games, watching videos, and leisure and entertainment has increased significantly. 38.3% of students spend more than 2.5 hours of “screening” for non-learning purposes each day, and 38.5% of students feel visual fatigue or dry eyes. .
