< At this point, one is stuck with the inherent acuity of the eye that cannot be further improved. This would seem to include the small-scale shape irregularities of the eye lens, cloudiness of the cornea, lens, and interocular fluid, density and function of cone cells at the center of the retina, and the hook-up to the brain, which might be improved by practice. >
Ron ,
I am not qualifued to disagree with any of those points , nor have I any reason to .
However , with regard to improving acuity , I must mention again that anyone who happens to have TWO pairs of identical or very similar prescription DISTANCE glasses , ought to try wearing BOTH pairs at the same time .
It DEFINITELY improves my acuity , although I suspect that is entirely due to a doubling of the correction for astigmatism .
It's like selecting a TeleVue dioptrix lens that is 0.25 or 0.5 diopter STRONGER than is strictly necessary .
I've not actually tried the Dioptrix , but I've experimented with a selection of negative corrector lenses , and the results were consistent with wearing two pairs of glasses , one in front of the other .
I really hope you , or others , can and will give this a try , rather than try to prove me wrong by theoretical reasoning !
Regards and clear lenses
Kenny
