But what ARE the consequences of wearing a minus lens, Otis? Better
vision? Certainly. More myopia compared to wearing nothing, compared
to wearing a bifocal, compared to wearing pluls? Certainly not. Thus
far, you are unable to prove that any of your interventions are
effective, bluster, verbosity, and obfuscation notwithstanding.

I did NOT. I KNOW you can find groups where the average refractive error
changes by -0.50D/year. I did not ask that.
I DO NOT CARE what rate you consider "correct". We know people get
nearsighted. You can even believe they all get nearsighted at the same rate,
with no respect for age, ethnicity, IQ, education, time spent in near work,
or working distance. They all get nearsighted at one-half-diopter per year.
FINE.
My questions are - where you find evidence that myopes get worse BECAUSE
they wear minus?
And where you find it a "proven fact" that human myopes get better by
wearing plus?
If you aren't going to answer these questions then don't bother responding.
The rest isn't relevant to the Rehm-Brown hypothesis.
The average "down" rate in my practice is of no possible relevance. Besides
the pitfalls of a self-selected sample, only about 1/3 of my patients are
nearsighted and only about half of those are actively changing. Do you
believe myopes get worse their entire lives?

Kids who DON'T wear glasses also change at 1/2D per year.
Please show us the studies that indicate wearing minus causes 1/2D
progression per year, or stop preaching myths as fact.

Please learn to use your mail reader to quote. I can't remember saying
anything like that. I might have said I'm liable if my prescription only
gives a pilot 20/40 vision.

Your reference is totally obscure to me - i.e. I haven't a clue what you're
talking about.

My kids are 19 and 23 and managed to avoid nearsightedness WITHOUT lectures
on taking personal responsibility for the shape of their cartilage.
In fact, 3/4 of the US population seems to do pretty well without your
ministrations.
