Pseudo-myopia, the anteroposterior diameter of the eyeball has not been lengthened, and the structure of the eyeball has not changed. It is only a change of physiological function. Therefore, glasses are generally not to be worn. After timely treatment and protection, the ciliary muscles are relaxed and the vision can be restored to normal. If you do not pay attention in the pseudo-myopia stage, and continue to develop, the fore and aft of the eyeball will become longer.
