I recently discovered that I have an astigmatism in one eye, which I can only partially correct with glasses. I don't need to wear prescription lenses day to day, but one thing I noticed immediately was how much easier high contrast text is to read. Without my glasses, any significant contrast has a slightly out of focus halo, making thin lettering just a tiny bit harder to read. I'm sure due to this condition that I can't speak for the majority of the population, but it seems to suggest this: everyone's eyes are different. Sometimes in tiny, subtle ways. In my case, a tiny bit less contrast helps tremendously with legibility, and I find dark themes easier to read because the halo is less pronounced. Other users might have a different experience. As much as possible, accommodating user preference (especially light / dark theme) will help those of us who need to tweak further tremendously.
