Answer:

Explanation:

In bright light, the circular muscles contract whilst the radial muscles relax. This causes the pupil to constrict and less light enters the eye. In dim conditions the opposite occurs. The circular muscles relax and the radial muscles contract, causing the pupil to dilate and allowing more light to pass into the eye.
