Hii aspirants
let me clear your doubt.
The iris is a ring-shaped membrane inside the eye that surrounds an opening in the center, called the pupil. The iris contains muscles that allow the pupil to become larger (open up or dilate) and smaller (close up or constrict).
I hope my answer will be helpful for you
Good luck
