People who prefer light theme over dark/night theme.. Why?

I just toggle based on time of day / lightness of environment.
I find my eyes are more strained when using light text on dark backgrounds in a light environment (and of course dark text on light backgrounds are a no-go at night). The only exception to this is my phone, where the battery gains from oled makes dark mode the only option for me. I hope Kbin gets a nice light mode toggle that can follow the system theme in the future.
