explan the function of iris pupil in the muscles connected to lens in human eye​

Answer 1

Answer:

Function of Iris:

The iris is a muscular diaphragm that controls the size of the pupil, which, in turn, controls the amount of light entering the eye. It also gives colour to the eye. The focal length of the eye lens is adjusted by the expansion and contraction of the ciliary muscles.

Answer 2

Answer:

The iris has an adjustable circular opening called the pupil, which can expand or contract to control the amount of light entering the eye. Ciliary muscles surround the lens. The muscles hold the lens in place but they also play an important role in vision.
