If all the lights are off except a distant one (like in a dark room with a tiny night-slight), noodles can't really see much (if anything). I know this because I dim the lights to get her to go into her cage at night, but when I have made it too dark, she has climbed to the back of her cage on the outside and started doing her bedtime ritual (thinking she was inside). She also will get spooked by my hand, even though I can see it- she appears to have trouble sometimes. In dim conditions, she can still function, but when it's too dark, she must rely pretty much on her memory and the feel of her cage. When she is covered, she climbs around and gets food/water etc, but outside of her cage in the dark, she doesn't know what to do.
She gets paranoid and will be more prone to bite at things around her because she can't see what they are.
In a dim room or lower light, she can see, but in darker conditions where I can still sort of see of, she cannot...or at least, if she can, she doesn't act like it.
It could also be an instinctual thing, where as a human, I am just more willing to walk around without being able to see everything perfectly.....
