The Pupil

The iris and the pupil control how much light enters the eye. The size of the pupil is controlled by muscles within the iris- one muscle constricts the pupil opening (makes it smaller), and another iris muscle dilates the pupil (makes it larger). This dynamic process of muscle action within the iris controls how much light enters the eye through the pupil.

INTERESTING EYE FACTS

1. The eyebrow is a line of hair above each eye. It forms a protective wall above the eye and keeps dust and dirt out of the eye.

2. Eyelashes are a protective hairy screen around the eye. They also help to keep dust and dirt out of the eye.

3. The eyelid is like a movable curtain of skin in front of the eye. It protects the eye from injury and controls the amount of light entering the eye.
