Oh, please. Locally, I'm doing good to get even cheap and horrible glasses for under $300. From Zenni, the last glasses I ordered cost $17. The most I've paid has been $63. I did discover one flaw-- maybe-- with my fancy $63 glasses from Zenni. The cylinder (correction for astigmatism) seems to be incorporated into the front of the high-index lens. This makes the lenses look warped in oblique lighting, as if the plastic is bent (though I think that's just the axis of the cylinder). There is also a slight ripple in the front surface. I can't observe these things by looking _through_ the glasses; I can only see them by looking _at_ the lenses, or more specifically at the reflections on the surface of the lenses. I don't know if it's an FDA requirement or just a custom, but all the lenses I have gotten from local opticals in the USA have a uniform base curve on the front, with both spherical and cylindrical correction taking place on the back surface of the lens.
