Do you sit in a bright room? Right now, during the night, I see your comment like this: https://i.imgur.com/c7fmBns.png, but during the day when the room is bright, I also see everything with light themes/background colors, otherwise it is indeed hard to see properly.

Unfortunately, in my case, it's not a matter of lighting conditions.

When it’s dark (I can’t stand bright rooms at night), I lower the brightness of my screens instead of going for dark mode. I have astigmatism and any tiny bright spot is hard to focus on. It’s easier when the bright part is large and the dark parts are small (black on white is best).

Same for me, has been my whole life. I complain about it all the time. It's well documented that people can read black on light far better and with less eye strain than light on black; yet there seems to be a whole generation of developers determined to force us all to try and read it. Even the media sites like Netflix, Prime, etc. force it. At least Tubi's is somewhat more readable.

Sometimes a site will include a button or other UI element to choose a light theme but I find it odd that so many sites which are presumed to be designed by technically competent people, completely ignore accessibility concerns.

The most common mistake I see (on this website at least) is the assumption that one's programming competence is equal to their competence in other things.

I feel your pain. For me it is the opposite: I get headaches from bright backgrounds because I'm light-sensitive.

Yeah I am the same.

Definitely in the minority on this one as dark mode is really popular these days.

Really hard to describe how it is literally physically painful for my eyes. Very strange.

I find dark mode much easier to read and far less eye strain. I guess it just shows that users should be the ones to set the preference. There are studies on monkeys showing light mode leading to myopia. Although lately I have come to learn there are lots of poorly done studies.
