Aaaand use f.lux (https://justgetflux.com/ https://justgetflux.com/). Daylight setting black on white may indeed be way too bright at night, but when you turn down amount of light produced - or let through to your eyes - by your monitor and combine it with the night adjustments from f.lux in my experience you are good even reading late. Of course, in addition I also only use some pretty dim LEDs from some x-mas decorations instead of the bright lamps everybody else seems to use when I walk around the neighborhood at night. I could not live with using those regular lamps any more. I've gotten used to having my rooms pretty dark whenever it's dark outside, light equivalent to maybe half a dozen candles. Both the ambient light and the monitor have to be adjusted. They can use dark mode all they want, if they leave a regular lamp on it still is very bright. Living like this I noticed how little light I actually need, by now I deliberately keep older - significantly dimmer than new - of those x-mas LED chains ("warm white" - more yellow by now), use the newer (still brighter) ones early in the evening, and later switch to the old even dimmer ones exclusively. And it still is more than enough, maybe three or four candles equivalent per room.
