(science) Try this at home. Go into a small room with a mirror, like a bathroom. Look closely in the mirror at your eyes; then turn off the light and make the room as dark as possible. If you cannot make the room dark, shut your eyes and cover them with your hands. Wait for several seconds, and then turn the lights on as you continue to look at your eyes in the mirror.

What changes do you notice in your eyes immediately after you turn the light on? Why do you think this change happens?
