Can someone explain night vision to me?

1.06K views

So if I have to go pee at night, I don’t turn on lights in the house but I do use the bathroom light. Before I turn on bathroom light, I keep one eye closed.

Afterwards, when I leave the bathroom, the formerly-closed eye can see in the dark well but the eye that got light is a bit terrible.

So I use the formerly-closed eye to navigate back to bed.

So how does night vision work?

Fun side fact; that’s why pirates wore eye patches, not because they lost an eye, but so they could transfer the patch from eye to eye when they went back and forth between above deck and below deck, so they wouldn’t have to wait for their eyes to adjust to the dark
