In pseudomyopia, the anterior and posterior diameters of the eye are not lengthened and the structure of the eye is not changed, but only the physiological function is changed. With timely treatment and protection, the ciliary muscle can be relaxed and the vision can be restored to normal. If the pseudomyopia stage is not taken seriously and continues to develop, the anterior and posterior axes of the eye will become longer and the structure of the eye will change, which means that it will become true myopia and must be corrected with glasses.
