200 degrees of myopia in children can be corrected. True myopia of 200 diopters in children is correctable but not treatable. Pseudomyopia 200 degrees can not only be corrected, and can be treated, treatment methods include eye rest, drops of paralyzing ciliary muscle medication and so on. Corrective methods mainly refer to wearing eyeglasses, including frames, corneal reshaping lenses and so on. Eyeglasses not only help children see clearly, but functional glasses can also prevent children from further increases in myopia. For children with 200 diopters of true myopia, if the myopia is relatively stable, you can consider wearing ordinary frame glasses to correct it. If the myopia grows too fast, it is recommended to wear functional glasses in time to prevent and control the growth of myopia. For children with pseudomyopia of 200 degrees, it is recommended that they seek medical attention to correct the myopia while targeting treatment.
