I prefer light mode because dark mode gives me a raging headache in under 10 minutes, not enough contrast or something, I’m not sure. It’s bad enough that if I’m pairing with someone and they use dark mode I’ve gotta frequently look away or do something like a shared follow mode where I use a light theme on my end - it sucks.

And maybe the science is old now, but in HS I did a report on eye strain and light backgrounds are typically better across the board. But who knows now.
