Students' "small glasses" have a high incidence and low age trend, and the problem of "small glasses" has become a hot spot in the society. A survey shows that the overall myopia rate of children and adolescents in China is 53.6%, including 14.5% for 6-year-old children, 36.0% for primary school students, 71.6% for junior middle school students and 81.0% for senior high school students. The task of myopia prevention and control is very arduous. So, how to prevent and control students' myopia?
1) Exposure to outdoor natural light for more than 90 minutes every day
Clinical studies have proved that increasing outdoor activities can reduce the incidence of myopia in children and adolescents. Therefore, parents should actively guide students to carry out activities or physical exercise in the outdoor sun, so that students can be exposed to outdoor natural light for more than 90 minutes every day at home. The school shall not occupy the contents irrelevant to physical exercise in the time arrangement of physical education, and ensure that primary and secondary school students have more than 1 hour of physical activities every day at school.
2) School classroom lighting should meet national standards
Classroom lighting shall meet the relevant national standards. All classrooms shall be equipped with artificial lighting, and the average illuminance on the classroom desk shall not be less than 300lx, and the illuminance uniformity shall not be less than 0.7; The blackboard in the classroom shall be equipped with local lighting, the average illumination value shall not be less than 500lx, and the illumination uniformity shall not be less than 0.8. If the average illuminance of the desk and blackboard is insufficient, and the blackboard is not specially equipped with lighting, it is easy to cause students' eye fatigue. Therefore, classroom lighting needs to be implemented in strict accordance with national standards.
