背景技术Background technique
目前，青少年近视问题日益突出，其根源在于青少年学业繁重，多数时间都在近距离使用眼睛，容易因用眼过度而导致眼疲劳，从而致使眼睛的调节功能降低，出现眼肌疲劳、睫状肌痉挛等现象，长此以往难免会导致视力下降。At present, the problem of myopia among teenagers is becoming more and more prominent. The root cause is that teenagers are busy with their studies and spend most of their time using their eyes at close range. Overuse of their eyes can easily lead to eye fatigue, which will lead to a decrease in the adjustment function of the eyes, eye muscle fatigue, and ciliary muscle fatigue. Spasms and other phenomena will inevitably lead to vision loss in the long run.
