Preamble: After the child is nearsighted, parents do not want the child to wear glasses and want to find some way to restore the child's vision to a normal level. Then we must let the child develop good eye habits, do not stare at the electronic screen for a long time, and if you want to heal, you need to have laser surgery, but there are certain age requirements, you need to wait until after the age of 18.
