The pupil is a tiny hole in the middle of your eye - the black dot - that allows light and colors in.
If too much light gets in, it could damage your eye. Because of this, the hole gets bigger in the dark and shrinks in the light. This
happens by a muscle opening and closing.
Six muscles coordinate
your eyes movements.
