Many people have a one-sided understanding that myopia is only related to overuse of eyes. Few people pay attention to the relationship between sleep time and myopia. In fact, the occurrence of myopia is closely related to the lack of sleep time.
The research of ophthalmologists shows that the function of local sympathetic nerve and parasympathetic nerve is out of balance, which is the pathological basis of myopia.
If the child is short of sleep for a long time, it will cause the whole body autonomic nerve dysfunction, and the whole body autonomic nerve dysfunction will inevitably affect the local sympathetic and parasympathetic nerves of the eyes, thus causing the disorder of the ciliary muscle regulation function, leading to the formation of myopia.
The fifth and sixth grade of primary school, the third grade of junior high school and the senior grade of senior high school are the high incidence period of myopia. At this time, teenagers often affect sleep because of too much homework.
Lack of sleep for a long time, the adjustment function of the eyes will be abnormal, resulting in the occurrence of myopia.
I believe that each of us will have a pair of bright eyes.
