Abstract: myopia is a process of gradual accumulation. It is not about the sudden outbreak in grade 4, but from grade 1 to grade 3. Many children have developed pseudomyopia. If they do not pay attention to and prevent it, it is easy to change into true myopia in grade 4.
increased by 5%. In the high school almost all classes were nearsighted,
. According to the relevant findings, the incidence rate of myopia was gradually increasing. With the increase of grade, the abnormal visual acuity rate increases gradually at the rate of 5% per year. The myopia of
high school students is also not optimistic. The abnormal visual acuity rate of grade one is about 95.61%, and that of grade two is about 95.77%. It can be seen that the incidence rate of myopia in high school classes is greatly improved compared with that in junior high schools, with a incidence rate of 96%, almost all the nearsightedness in the whole class. There is no common vision screening for senior three students in senior high school due to academic stress, but it is estimated that the myopia of senior three students should exceed 96% according to the development trend.
myopia increased by more than 200 degrees after the summer vacation?
many parents will find that it is no problem for their children to look at the blackboard before the holiday. As a result, after a summer vacation, they find that the original glasses are not enough or the handwriting on the blackboard is blurred. The fourth grade of
is a barrier. The data of
show that the fourth grade of primary school has become a barrier, and the abnormal visual acuity rate is about 46.98%. In other words, by the fourth grade, nearly half of the students in the class had abnormal vision.
myopia is a process of gradual accumulation. It is not about the sudden outbreak in grade 4, but from grade 1 to grade 3, many children have developed pseudomyopia. If they do not pay attention to and prevent it, it is easy to change into true myopia in grade 4.
myopia increases by 50-100 degrees every year?
children’s myopia has another biggest feature, that is, the degree will increase every year. Generally, for children who come to the hospital, the annual average increase of myopia of children around the age of 10 is 50-100 degrees. A small number of people have an annual increase of myopia of 200 degrees or more.
from primary school to high school is a special period of rapid rise in myopia. Now, on the one hand, electronic products are popular, on the other hand, there is great pressure to read, which makes the rise of myopia faster. Many children who come to see a doctor are still in junior high school, and their myopia has reached 56 Baidu.
watching iPad for ten minutes = watching TV for 30 minutes
through data comparison, mobile phones have the greatest impact on eyes, followed by iPads and laptops, while Kindle and paper books have relatively little impact.
so, is it the same for children?
according to the experimental data, the destructive power of mobile phones and iPads on children’s vision is much higher than that of TV and projection. In general, the degree of eye fatigue of children watching mobile phones for ten minutes is equivalent to watching TV for 30 minutes.
but whether you are watching mobile phones, iPads or TV, you should pay attention to rest. Watch for 30-40 minutes and rest for 10 minutes, or look into the distance, so that your eyes can get proper rest, which can slow down the rise of myopia.
outdoor exercise for more than 3 hours a day can prevent myopia. There are three reasons why the eyesight of primary and middle school students in
is getting worse and worse. One is the overdraft caused by schoolwork pressure. Second, pupils generally have incorrect eye habits. Third, electronic products that frequently enter the family.
proper rest is the best way to protect your eyes. Children can prevent myopia by maintaining outdoor sports for more than three hours a day.
