Abstract: why do so many people have myopia? In big cities, most of the information we rely on comes from books and the Internet. It can be said that 90% of the information is obtained by close reading. To adapt to this way of life, teenagers are prone to the so-called modern civilization disease – myopia., There are more and more “small glasses” in China. In the glasses store, most new users are children. In the 1970s, less than one-third of teenagers aged 16 to 18 were myopic. Nowadays, most teenagers suffer from myopia. The incidence rate of primary school myopia in ancient Chinese literature search in 2015 was 22.8%, 55.2% for junior high school and 70.3% for senior high school students. The problem of myopia of primary and middle school students has become a social problem, which should be paid great attention to by the whole society., Why do so many people have myopia? In big cities, most of the information we rely on comes from books and the Internet. It can be said that 90% of the information is obtained by close reading. To adapt to this way of life, teenagers are prone to the so-called modern civilization disease – myopia., However, it also relies on close reading to acquire knowledge, and also uses computers, iPads and mobile phones. In foreign countries, the proportion of myopia is much lower than that in China. The myopia rate in the United States and Germany is less than 10%. According to the recent data on the website of the French Ministry of health, the proportion of myopia among adolescents under the age of 20 is about 20%. The myopia rate of primary and secondary school students in Canada is also at a low level in industrialized countries., Why? The main causes of myopia are closely related to too long study time, reading and using electronic products, and less outdoor activities. Professor Morgan of the Australian National University said: “do not go out and focus on close areas (such as writing and reading). The combination of the two situations further worsens the problem. However, if children have enough time for outdoor activities, they can enjoy learning and avoid visual impairment.” Chinese children now spend an average of only one hour outdoors every day, while Australian children spend four hours., The fundamental idea of protecting the eyesight of primary and secondary school students in Canada is to reduce students’ learning pressure, reduce students’ eye intensity, and let children have more time to contact the sun. Canadian middle school students spend more time on exercise than on homework. Canadian primary and secondary schools The class hours (especially in primary schools) are generally short. The legal class hours in most provinces are 9-11 a.m. and 1-3:30 p.m. every day. In such a short class hour, the intensity of students’ eye use in class will naturally not be very large. Ensuring students’ outdoor activity time is another key to ensure the eye hygiene of middle school students. In Canada, the education department prohibits dragging classes and making up classes Behavior, and most provinces stipulate, The outdoor activities of primary and middle school students during their study in school shall not be less than 2 hours a day (the outdoor activities of junior students must reach 4.5 hours a day) Incidence rate of myopia is only related to outdoor time. Research also shows that children do not matter what they do outside. No matter sports or picnic, as long as they spend more time in the outdoor, the incidence rate of myopia is low. A middle school teacher in District 14 of Paris told reporters that French schools now pay more and more attention to students’ outdoor sports and believe that all kinds of sports activities can effectively prevent myopia. A professor of Paris Medical University told Le Figaro that there was a certain link between the lack of natural light and the increase of myopia. Therefore, many French schools pay more and more attention to the natural light in the classroom and library, as well as creating a bright reading environment. Because exposure to sunlight can promote the retina to release a chemical substance and slow down the increase of axial length of the eye, which is the biggest cause of high myopia., These opinions and practices deserve our study. In contrast, our primary and secondary school students spend a lot of time doing their homework indoors. From childhood to primary school to junior high school, from junior high school to senior high school, and then to the college entrance examination, we have been trapped in the sea of questions and can’t extricate ourselves. The deterioration of eyesight is in direct proportion to the increase of learning time.,

exam oriented education and enrollment rate have become two big favours, driving more and more primary and secondary school students to join the ranks of “low headed people”. It is common for primary school students to do their homework every day and fall asleep at 10 p.m. Weekends are no exception, busy making up lessons. If you have a little free time, you should seize the time to play iPad and mobile phone, and there is little time for outdoor activities. Indulging in video games is ruthlessly swallowing children’s vision. Myopia has risen sharply among primary and secondary school students, which is almost inevitable.
and
to protect eyesight is to protect talents. We can’t let our nation become a “glasses family”. There are more and more “small glasses”, which reflects the disadvantages of China’s education system from one side. To treat this disease of modern civilization, we need to rely on the joint efforts of education authorities, schools, teachers and parents to protect children’s eyesight without delay. We should adhere to the spirit of the notice on reducing students’ learning burden and implement it in accordance with the relevant provisions of the regulations on school health work. Schools should incorporate the protection of students’ eyesight into school work measures, and list the protection of students’ eyesight and the prevention of myopia as one of the duties of head teachers, so that students can have more time to go out of class, go out of home, contact the sun, get close to nature and stay away from myopia. When do primary and middle school students have more exercise time than homework, and the time for extracurricular activities should not be less than 2 hours a day, “small glasses” may be greatly reduced.
