I use light mode during the day and dark mode from dusk till dawn. I do this because I find it more comfortable, not because I'm told by someone or a study that it's better.
that's fair, the study didn't convince me it was better, it just prompted me to switch back to white, because, actually, I don't know, and then I found that _if_ it made any difference, it was probably positive, but, even though I sit at the screen from dusk till dawn, I find no difference in how pleasant light or dark mode it, it just makes so little difference to me that I don't care :)
