> I am mainly interested in what tools, settings, and themes people with astigmatism use, and if you have any preference for light or dark themes. Personally, I cannot stand light, whether it is physical light or light on screens.
Contrary to your preference, I believe a light theme (black letters on white/gray background) is better for astigmatism. With a dark theme, the bright letters will bleed into the dark areas surrounding them. (At least that's how I experience it. I have only slight astigmatism, but the ghosting effect already annoys me for dark themes.)
If you really want to stick to a dark theme, I would select something where the text is not too bright. The Solarized Dark Theme that you mention seems OK in this regard.
