Children with myopia resulting in visual acuity of 4.8 may be caused by true myopia or pseudomyopia. Generally, it is more difficult to recover from true myopia, but patients with pseudomyopia can recover orthopia and improve their visual acuity by developing good eye habits. 1. True myopia: True myopia is caused by congenital poor eye development, poor eye posture, etc. The anterior and posterior diameters of the patient’s eyeballs are variable and long, and after parallel rays of light are injected into the eyeballs, the focal point of the eyeballs falls in front of the retina and the image cannot be clear. Because true myopia cannot be reversed, it is more difficult for children to regain their vision, which can be improved by wearing glasses to correct myopia. 2. Pseudomyopia: Pseudomyopia can occur when children use their eyes for a long time at close range and their ciliary muscles spasm. If children with pseudomyopia develop good eye habits, they can regain orthopia and improve their visual acuity. It is recommended that children with myopia consult a doctor to evaluate their condition and follow the doctor’s instructions for treatment.
