Your eyes adjust to the available light to a radical degree. If you are in a room with 5 lights bulbs and turn all but one off, it will probably only feel 25%-50% darker.

I was trying to make my bedroom as dark as possible so I could sleep in. I turn off the lights, it felt dark for like 2 seconds until my eyes adjusted. Then there was all this light coming in around my curtains, it felt just as bright as before. So I tapped those to the wall. Man it was nice and dark for a few more seconds then my eyes adjusted and there was all this light coming in from under the doors. So I put a towel in front of that. Then it was dark, but I could still see a little because it turns out my curtain tapping was not great AND there was light coming in around the doors. My point being, if you are young and healthy your eyes can be really good at adjusting to low light conditions without you even noticing.

I don’t know why but the idea that there might be daylight savings time on the moon is hilarious.
