Some people have conditions that make dark mode text harder to read, not easier. Astigmatism is one of them. Also, myopia.

It can cause "halation" which is like a foggy glow around objects which are brighter than their relative surroundings. Like a streetlight at night, or white text on a black background.

I have this to some degree but I still prefer dark mode most of the time.

Thank you for the explanation. I thought it’s the other way: the dark mode somehow provokes your eyesight to become worse. For me, I used white-on-black since the dawn of time (with CTR displays) and even then it was much easier on my eyes. Right now, I have an iPhone’s frontal sensors dirty (have a broken screen) and it manages auto-brightness wrongly to some degree. I have a dark theme all the time, and I tried to make it automatic (light during the daytime and dark during the nighttime, obviously). So so so horrible to me! Switched it back almost immediately.
