A 12 year old child with 200 degrees of myopia may not always be able to recover, if it is true myopia can not be recovered, while pseudomyopia can be recovered. For a 12-year-old child with 200 degrees of myopia, the first thing you need to do is to go to a regular hospital for a dilated optometry examination to distinguish between pseudomyopia and true myopia. Pseudomyopia is mainly due to ciliary muscle spasm and is temporary and reversible. True myopia, on the other hand, is caused by the lengthening of the visual axis and is currently irreversible. If your child has pseudomyopia, your child’s vision can usually be restored by correcting your child’s bad eye habits and relaxing the eye muscles. If the myopia is true myopia, it cannot be restored and the patient can only wear glasses to correct the myopia and improve vision. It is recommended that children with myopia seek medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
