I have astigmatism, and I read without glasses (by holding the device close enough to the eyes). I find black-on-white more readable in general, but red-on-black is equally readable at night.

Similarly. Astigmatism, glasses, and dark mode is a lot easier for me.

I also wear glasses all the time, even computer glasses.

I’m nearsighted, maybe that’s a differentiator? Although I‘m not sure if astigmatism always comes with nearsightednesd or not.

I have slight hyperopia, but it's dwarfed by the much more significant astigmatism.

I'm in the same boat with corrective lenses. It would be interesting if glasses/contacts had this side effect.
