[QUOTE="Steve4Physics, post: 6867621, member: 681522"] That sounded interesting so I tried an experiment. With the glasses 'the wrong way' I rotated them to get the astigmatism axis correct (for one eye at a time of course). Vision in each eye was then (at least subjectively) the same as when wearing the glasses normally. I also tried it with some (non-prescription) reading glasses. Having the glasses the wrong way made no perceptible difference. I presume any spherical aberration/concavity effect is small enough to be neglected. [/QUOTE]
