Myopia, whether acquired or congenital, cannot be cured. Since myopia is mostly caused by an increase in the length of the front and back of the eye, it is impossible to shorten the already growing eye axis back to its original shape, and the only way to remove glasses is to wear glasses for correction or myopia surgery. However, the length of the eye axis and the changes in the fundus of the eye cannot be changed. Therefore, myopia is irreversible. With the increase of age, physical development and the increase of the burden of reading and looking close to the eyes, there is a tendency for myopia to gradually deepen in adolescents. Myopia can be controlled by scientific and standardized ophthalmic treatment and self-cooperation.
