Don’t be a “glasses party” from now on

Abstract: the vast majority of myopia occurs in teenagers. Because teenagers have strong eye regulation and high adaptability to close work and study, they are not easy to get tired when looking near.

survey found that the myopia rate in China has been close to 30%, most of which are concentrated in school age. 22.7% of primary school students suffer from myopia, the myopia rate in junior middle school has soared to 55.8%, 70.3% of senior high school students wear glasses, and the myopia rate of college students is as high as 80%. In some places, the proportion of students who fail to pass the college entrance examination and professional restrictions is as high as about 85%, most of which are caused by poor eyesight.

I was shocked by the survey results. What was the reason for such a high “appearance rate”?

and

environmental adaptation theory 22.7%

and

had small eyeballs in early childhood, most of them showed hyperopia, and the eyeballs increased to emmetropia with age. In this development process, the eyeball becomes myopia in order to meet the needs of this regulation.

and

convergence theory 25.3%

and

also need to strengthen the convergence function of simultaneous inward rotation of both eyes when they are used for adjustment in close work, which can lead to the compression of ocular muscles on the eyeball and the extension of ocular axis.

regulation theory 42.9%,

the vast majority of myopia occurs in teenagers. Because teenagers have strong eye regulation and high adaptability to close work and study, they are not easy to get tired when looking near. However, if the ciliary muscle is excessively tense for a long time, the ciliary muscle will be tired or even spasm, resulting in regulatory myopia. If it is not eliminated in time and continues to develop, it can become irreversible true myopia.

nutritional constitution theory 9.1%

from some data analysis, genetic or acquired factors lead to the lack of trace elements such as cadmium, strontium and zinc and the weakness of constitution can also affect the occurrence of myopia. The four theories of

and

are relatively independent, but the first three theories are basically caused by improper daily eye habits. Bad eye habits will directly lead to the formation of myopia. The common points are as follows:

① close reading.

② incorrect reading or homework posture.

③ read when the light source is too bright or too dark.

④ long time fatigue reading.

⑤ the reading is too dazzling, resulting in eye discomfort.
