Currently, myopia is a widespread concern in the society, and in recent years the country has been very concerned about the problem of myopia, especially among teenagers. When myopia occurs, the first step is to clarify whether it is true myopia or pseudomyopia. In the case of pseudomyopia, the myopia can generally disappear after the ciliary muscle is paralyzed by dilating the pupil. Pseudomyopia can be relieved or even disappeared by reducing near eye use and getting enough rest. True myopia is usually caused by a lengthening of the eye axis, and there is no way to reverse the lengthening of the eye axis, so there is no way to reduce myopia from this point of view. However, if myopia is detected early, there are ways to slow down the progression of myopia. If the presence of true myopia is detected at an early stage through a regular dilated eye exam, the right glasses can help slow down the progression of myopia, and keratoplasty is significantly better than frames in controlling myopia progression.
