Question

What Job does the pupil of the eye do

Answer 1

The iris contracts and dilates involuntarily and changes the size of the pupil. The whole job of the iris and pupil is to control the amount of light that gets into the eye. It's called a pupillary reflex, and you have probably noticed that a person's pupils are smaller in bright light and bigger in low light.

Answer 2

Hi

The pupil is a hole located in the centre of the iris of the eye that allows the light to strike the retina . It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly , or absorbed after diffuse reflection within the eye that mostly miss existing the narrow pupil . Pupil are smaller in bright light and bigger in low light which helps us to see.

May it is helpful for you.
