What is important - is what an OD does to help his own child protect
his distant vision against serious myopia.

Other ODs and MDs have insisted that there own child wear a plus - to
avoid entry, in the pseudo-myopia, or "eye-strain" stage (before and
excessive minus induces axial-myopia.)
True, effective prevention is indeed the second-opinion.
Enjoy,
