(1) Wearing lens is the most basic measure to correct myopia in children. For mild myopia, if it does not affect life and study, it is not emphasized to wear glasses immediately. For moderate and severe myopia, since the distance vision drops significantly, not correcting it will inevitably affect life and study, so wearing glasses is necessary. Before getting glasses, one should first go through shadow examination to figure out the true degree of myopia. The principle of getting glasses should be to take the lowest degree of lens that can correct the vision to the best.
