Is there some way to make this comment a billboard?
The lenses are manufactured per individual according to their need. Granted it's within a spectrum of choices such as it's -1.5 or -2, not -1.66421 (right?). Then one can add features to the lenses like anti-glare, anti-scratch, spectrum, blue light filter. Insurance covers 100%, and it's not a lot. But the frames?? They're very, very small amounts of metal and mass produced. What a sham. But yeah I do buy them at Lens Crafters after my optometrist appointment for the convenience.

Usually right, typically in 0.25 steps. Then there's Zeiss i.Scription [0], with lenses produced not only to weird numbers, but also to correct higher order deviations than just spherical and cylindrical.
I haven't tried those yet, seeing slightly changing test results on the needed standard correction, so I assume that higher order correction would be a short term improvement only.
The steps are .25 on the diopters. I suspect I would have slightly better vision for a while if they went to .125 as there have been plenty of times I felt that her 1 and 2 were bracketing ideal. I don't know the resolution of the axis and cylinder numbers.
