It is hardly likely that someone who made a hobby of using the
instrument under all sorts of conditions and spent decades doing so
would be incompetent in its use. Dr. Bates had remarkable eyesight
after he cured himself of presbyopia, so it should not be surprising
that he was more skilled in the use of the instrument than many
others.
His findings with the retinoscope also stand the tests of experience.
People who have discarded their glasses and begin to cure their poor
eyesight notice dramatic changes in their quality of vision, depending
on their emotional state and other factors. This is something that
will often vary little if glasses are worn, or go unnoticed if the
assumption is held that the quality of vision does not change both for
the worse and for the better depending on how the mind is being used.
The variability of the quality of vision has become so obvious to such
people (including myself) that there is no need to question Bates's
accuracy with the retinoscope. The fact should be obvious to anyone
with perfect sight, as nobody with perfect sight has perfect sight all
of the time. - Kiesling
