OK in real life after you have been sitting ina dark room or dark area for
some time, and your eyes adjust u can see in the room u are in. Not every rom
is total darkness. Can it be set up that if u are sitting in one room for a
long periodof time it is not all ways dark. You should be able to see in that
room alone. I understand if you are in a cave this doesn't make since, but
sitting in the church or inoutworld when the moon is out. There is not total
darkness.
