There are many causes of myopia, and eye fatigue is certainly one of them. However, I personally believe that the reason for the sudden increase in myopia rate is the lack of natural light in the human eye. Human Eyes From the agricultural era, industrial era, to the current Internet of Things era, the biggest change in the social environment is lighting. What enters the eyes has changed from the long-term outdoor reflected natural light in the past to the current indoor direct screen artificial light.
Myopia occurs when the axial length of the eyeball grows too fast, stretching the eyeball and causing the retina to move backward, causing the distance between the focus of light and the retina to become longer, resulting in blurred images.
When people do not have free time to go outdoors due to work or study, the eyes are exposed to high-intensity natural light stimulation, which leads to reduced dopamine secretion, resulting in thinning of the choroid and accelerated growth of the axial length of the eye, promoting the occurrence and development of myopia. In addition, insufficient natural light stimulation can also lead to abnormal development of the eyeball and cornea, which can also induce myopia.
Nowadays, myopia has tended to develop at a younger age. More and more children and adolescents suffer from myopia at an early age, and adults directly progress to high myopia. Therefore, children are encouraged to go outdoors more. The focus is not on activities, but on giving eyesight. Increase natural light stimulation to prevent the occurrence and development of myopia.
