Properly worn myopia glasses will not worsen myopia.
Myopia is mainly caused by the lengthening of the eye axis, which causes objects to be imaged before the retina. Nearsightedness glasses are concave lenses, the principle is through the concave lens on the refraction of light, so that the position of the object imaging just in the retina, at the same time, the ciliary muscle of the eyeball to maintain a certain degree of adjustment, so that the eyes can clearly see objects at a distance.
If myopia occurs, you need to consult a doctor as soon as possible, through professional optometry examination, with the appropriate number of myopia glasses, to prevent further deepening of myopia. If you are nearsighted but do not wear glasses, the ciliary muscle is in a state of high tension for a long time and cannot be relaxed, which is easy to form visual fatigue, but will deepen the degree of myopia.
