Abstract: in recent years, the proportion of myopia among primary and secondary school students has increased year by year. Few students do not wear glasses in primary and secondary school classes. From the overall situation, the myopia rate of school students remains high, and the phenomenon of younger age is becoming more and more serious., Myopia is not a new topic, but I don’t know when myopia began to move towards younger age. More and more children are becoming little four eyed. So, what causes children’s vision loss? Are there any effective prevention and treatment methods for myopia?, Myopia is becoming more and more serious. In recent years, the proportion of myopia among primary and secondary school students is increasing year by year. Few students do not wear glasses in primary and secondary school classes. From the overall situation, the myopia rate of school students remains high, and the phenomenon of younger age is becoming more and more serious., There are many reasons for myopia. A few years ago, according to the national statistics on myopia, about 60% of myopia is caused by heredity, and about 40% is caused by acquired bad habits. However, in recent years, the proportion of people with myopia caused by acquired bad habits has far exceeded those with genetic myopia., Science has proved that myopia above 800 degrees is caused by heredity, and fatigue alone will not reach 800 degrees. But not paying attention to eye hygiene, watching TV and surfing the Internet for a long time will reduce eyesight., Take multiple measures to prevent myopia. Myopia can be prevented, even if it is congenital. If you pay attention to exercise and eye methods, it will effectively slow down the decline of vision.,

myopia is becoming more and more serious. In recent years, the proportion of myopia among primary and secondary school students has increased year by year. Few students do not wear glasses in primary and secondary school classes. From the overall situation, the myopia rate of school students remains high, and the phenomenon of young age is becoming more and more serious.
there are many reasons for myopia
a few years ago, according to the national statistics on myopia, about 60% of myopia is caused by heredity, and about 40% is caused by acquired bad habits. However, in recent years, the proportion of people with myopia caused by acquired bad habits has far exceeded those with genetic myopia.
and
scientifically prove that myopia above 800 degrees is caused by heredity, and fatigue alone will not reach 800 degrees. But not paying attention to eye hygiene, watching TV and surfing the Internet for a long time will reduce vision.
take multiple measures to prevent myopia
myopia can be prevented. Even if it is congenital, if you pay attention to exercise and eye use methods, it will effectively slow down the decline of vision.
there are misunderstandings in the prevention and treatment of myopia
a student’s parent said that since her child wore myopia glasses, the degree of myopia has increased year by year: more than 100 degrees in the first year, more than 200 degrees in the second year and more than 300 degrees in the third year. She felt that wearing nearsighted glasses could only make her eyes more and more nearsighted.
but this is not the case. People with eyesight below 0.6 generally wear glasses. Wearing glasses can only make myopia see clearly within the visual range of the classroom. At school, children use their eyes more. From the situation in recent years, whether they wear glasses or not, their eyesight is declining.
many parents ask the doctor to issue a myopia certificate and want the teacher to transfer the child to the front row and see clearly. In fact, the students sit in front of and behind the fifth row. Under normal circumstances, it is difficult to see light beyond 5 meters to cause myopia. If you are already short-sighted, wear glasses with the same degree. The closer the seat is to the blackboard, the faster the degree of myopia increases. Another misunderstanding is laser surgery for myopia. Laser surgery is to correct myopia by changing corneal curvature. But there are two preconditions for surgery: one is over the age of 18, and the other is that the diopter is relatively stable within two years. Because primary and middle school students are in the learning stage, they use more eyes and their eyesight is constantly changing, so they can’t choose laser surgery.
