China is a myopic country, but myopia is still an unsolved mystery, and it is now more recognized as a result of the combined influence of genes and the environment. There are no good treatment options for genes for the time being, so we won’t talk about them here. Let’s talk about what can be done: 1, increase outdoor exercise. This is the latest research hot spot, research shows that sufficient light can increase the secretion of dopamine. 2, correct reading and writing posture. This is mainly based on the mechanism that over-adjustment can trigger the development of myopia, so parents need to monitor their children’s bad habits. 3, OK lens (keratomileusis) to slow down the progression of myopia. This is also a hot topic of research, but not everyone is suitable. There are several misconceptions: Wearing glasses will deepen the degree of myopia. It is not true, but instead, not wearing glasses will deepen myopia. Can myopia be “corrected” back to normal? This is also a misconception, if the regular medical optometry shows that there is already myopia, then it will not become normal (orthokeratology), all we can do is try to slow down the development of myopia.
