Question

What are the functions of iris and pupil?

Answer 1

FUNCTION OF IRIS AND PUPIL:-

The pupil is essentially a hole in the center of your iris that controls how much light enters the eye. It's size is controlled by the relaxing and contracting of the iris. When there is high light intensity, the pupil shrinks while it grows in low light intensity. This is to ensure there is enough light for vision without damaging the sensitive retina.

Answer 2

Function of pupil :

In low-light conditions, the pupil dilates so more light can reach the retina to improve night vision.

Function of iris :

Simply Iris is a dark diaphragm that prevents extra light to enter the eye.
