Answer:
Iris acts as the aperture manager of the eye. It is a group of circular and longitudinal muscles, which work alternately changing the pupil.
Explanation:
A pupil is an aperture through which light enters the internal of the eye.
- During the distant vision, the pupil becomes narrower as iris contracts.
- And during the near vision, the pupil becomes large as iris relaxes.
So, the size of the pupil while regulating the light is controlled by the iris.
