Dark themes could always be set since win3 Accessibility settings. High contrast. No need to wait. 2 colors works Best for me :) As for the eye. It works as soon a few photons meets the cones and stabs. No photons, ko work. Dark mode sends less of photons. Thus, the eyes aren't in need to use up the purpura and whatever. They're not producing chemical reactions and reaction waste. So much better for longer sessions
