It is possible for people who are just nearsighted to return to normal, because being just nearsighted indicates that they may be in the stage of pseudomyopia. In order to distinguish between true myopia and pseudomyopia, once you experience a decrease in vision, you need to go to a regular hospital early for a dilated eye exam, through which you can distinguish between true myopia and pseudomyopia. Pseudomyopia is a condition in which the eyesight decreases, but there is no myopia after the dilated eye exam, which is called pseudomyopia and is mainly caused by unreasonable eye habits. After this situation, you must maintain reasonable eye habits and avoid excessive eye use, and you can also use low-concentration atropine drops topically to treat pseudomyopia. Usually after a period of rest, pseudomyopia can return to normal.
