The "Box-Camera" theory of the eye - FAILS - every time.
« on: August 10, 2015, 10:43:59 AM »
I am personal friends with ophthalmologists.  But their theory is proven to be false.  Plus-prevention is possible,
but difficult.  Here is the reason, no optometrist with "bother" to discuss true prevention with
you - when you can still read the 20/40 line.

(We know for certain that the natural eye always "goes down" when you place a strong minus on it.) 

But you will never hear an OD VOLUNTEER this true scientific information to you - when you can still read the 20/40 line.

For those interested in concept and theory - here is a chapter that discusses these issue.

The "Box camera" theory (developed by Dr. Kepler, and refined by Dr. Helmholtz), is a good theory.
I use it myself for many explanations.  But it just fails to represent science and experimental facts.

The minus lens "works instantly", and few people will ever question that FIRST minus lens,
that will "take down" your distant vision, more or less, permanently.

I do not blame the OD. Very few people have a desire for prevention, while they
can still read the 20/40 line, and the minus is so effective - and wonderful.

Only much later, do they realize how the damage that minus is certain to
do to your distant vision - for the rest of your life.
