What is pupil and what is the function of it?

Dear student The pupil is a hole located in the centre of the iris of the eye that allows light to strike the retina.its function 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. Regards
