Question

What would happen to the size of the pupil when a person enters a well-lit room from a dark room?

  1. Decreases
  2. Increases
  3. Stays the same
  4. None of the above

hintHint:

We narrow our eyes in bright light. The size of the pupil is controlled by the iris

The correct answer is: Decreases


    The pupil is the opening in the center of the iris through which light passes. The iris controls the amount of light entering the eye by adjusting the size of the pupil. When exposed to bright light, it shrinks to protect your eyes and block light. Constriction (narrowing) of the pupil is called miosis.
