He certainly can say that once you start wearing that minus -- your
vision will go "down" at a rater of -1/2 diopters per year. But no
one has attempted true-prevention BEFORE that first minus was
applied.
Let us Just say that Mike prefers his majority-opinion "Shotwell"
study, while prevention-minded people prefer the Oakley-Young
study. The jury is still out on the subject of true prevention
BEFORE you start wearing the minus.
I have also posted a short summary by Young (Oakley-Young)
which shows that "under-correction" and a +1.5 diopter
reduces the "down" rate to about zero diopters per year.
For children who were at zero (and STARTED) the plus -- could
have kept their distant vision clear through the school years.
However that is just the second-opinion.
Depends on WHICH study you trust.
Best,
Otis
