    I have astigmatism too and for me it looks just as bad when inverted, a blurry mess of black on white.

    To me, what makes one a better choice vs the other has more to do with my environmental lighting.

    • If I’m on a place with a lot of light, the screen being black makes it have reflections so I prefer black on white in those cases.
    • If I’m in a dark place, the bright screen makes the screen itself the primary source of light which is not good for my eyesight, it can make my eyes feel like burning/tired after a while.
