I've been using light themes for some time now, after years of dark mode-ing everything. It actually works better for my eyes, at least where I'm able to set the background to be just a bit off-white. And like the author, when I've pasted screenshots into discussions, I've received jokes about my choice. You know, the gifs about people in dark rooms being blasted with light from their monitor. And ironically jokes about eyes burning, when this is friendlier to my eyes than dark mode was.
