Usually sitting on the moon does not improve myopia. There are two types of myopia, refractive myopia and axial myopia. Axial myopia is more common in daily life, that is, as myopia gradually deepens, the eye axis also lengthens, usually every 1mm of eye axis lengthening, myopia will deepen by 300 degrees. However, both refractive myopia and axial myopia are changes in the shape of the eyeball itself, and cannot be improved through menstruation or recuperation. Therefore, for adults, the only way to restore normal vision is through laser myopia surgery.
