That would be surprising since ancient humans didn't sleep in total darkness either; they got light from the moon and stars.

- sanoli 12y agoI though the same thing. Anyone who's ever been camping with no other light source other than a full moon will remember how much light (I guess is it's pretty blueish?) the moon puts out. But, maybe it's not too much, since our eyes are probably very night-adapted when there's no other light source?
