Analyze the causes of myopia in children
As we all know, myopia among primary and secondary school students is getting more and more serious. So how can we better prevent myopia?
The real cause of myopia
The real cause of myopia is that the eyes keep the same action for a long time - close viewing. It can be said that the combination of the two factors of long time and close distance is the real cause of myopia. Sitting posture and light are to avoid long time and close distance. Keeping the same action for a long time can also cause damage to other parts of the body. For example, long-term bending over can easily cause herniated disc; long-term use of the mouse will cause soreness in the right shoulder; long-term work will cause calluses on the hands.
The human body has a protective mechanism. When it finds that you keep a movement for a long time and there is a possibility of harming the body, it will first remind you through numbness and pain; if you do not change and still keep the movement for a long time, then either the body will be injured, or the body will start the compensation mechanism to adapt to your requirement of keeping the movement for a long time through self-change. For example: calluses on the palms and bodybuilding to increase muscles.
Myopia is also the body's adaptation to the task of long-term close viewing. Under the mobilization of the body's compensatory mechanism, the eyes actively change the physiological structure and lengthen the eye axis to adapt to this high-intensity close viewing work. Once the physiological structure changes, it is impossible to turn back.
Misconceptions about brightness
Many parents believe that reading in the dark will reduce vision. In fact, the lack of light in the dark is not the real reason for myopia. The real reason is that the eyes need to look at things at close range because of the lack of light in the dark. So, it is still a question of distance. If you can keep looking at things at a distance in the dark, you will not be myopic at all. Let me give you an example and you will understand. Will looking at the stars at night cause myopia? Of course not, looking at the stars is an effective way to improve vision.
Looking at the stars in the dark will only make your vision better
So, whether the light is dark or not has nothing to do with vision, long time and close distance are the key factors.
