An in-depth analysis of the causes of myopia in 70% of Chinese adolescents

Low age myopia has become a common phenomenon in our country. It's shocking that 70% of the young people in our country are near sighted. On the bus, you can always see many primary school students with thick glasses and a big schoolbag. In China, the young people have no fun in childhood, and they are under academic pressure more often, which is also an important cause of myopia Reason!

According to the latest research report of the World Health Organization, the number of myopia patients in China is up to 600 million, almost half of the total population of China. The myopia rate of high school students and college students in China has exceeded 70% and increased year by year. The myopia rate of teenagers is the highest in the world, and the myopia rate of primary school students is also close to 40%. By contrast, the myopia rate of American primary and secondary school students is only 10%. Related article link: http://www.4hw.com.cn/life/jiankang.html

What are the reasons behind the myopia in 70% of Chinese teenagers? There is no direct evidence that which gene determines the occurrence of myopia. Among the three factors (heredity, environment and Nutrition) that induce myopia, scientists believe that environmental factors play a greater role in the occurrence of myopia. Electronic screen, bad light, incorrect posture, too long use of eyes and too close to the eyes are all bad eye environment or habits. Related article link: http://www.4hw.com.cn/life/jiankang.html

The high incidence of myopia is directly related to the concept of family education in China. Experts say that on the one hand, parents pressure their children to increase the intensity and frequency of their study in order to get higher scores in the exam, which results in little time for teenagers to relax through outdoor activities. On the other hand, more and more technology products (smart phones, tablet computers, etc.) make children often stare at the electronic screen for a long time, which leads to the increase of eye intensity and the decrease of blinking frequency. These are all factors that cause vision loss Related article link: http://www.4hw.com.cn/life/jiankang.html

Unfortunately, not only parents, but also some schools did not realize the harm of electronic products to the visual health of young people. Instead, they promoted the use of tablet computer teaching. This will not only impose the risk of myopia on children, but also aggravate the visual impairment of myopic children, and further push them to the ranks of high myopia.

The latest evidence shows that the occurrence of myopia has the characteristics of gradual aging. In the 3-6-year-old group, about 2.5% of children are myopia.
