In daytime, you see an object most clearly by looking straight at it. In the dark turn your head slightly and let your eyes continue con-tinue to look straight ahead. This allows you to see what is in front much better, because the retina, or Image plate, in your eye Is more sensitive in the side areas than it is in the center. You can demonstrate this by a pin hole in a 12-inch square sheet of cardboard.
