Explanation:
Detailed explanation-1: -The cornea is shaped like a dome and bends light to help the eye focus. Some of this light enters the eye through an opening called the pupil (PYOO-pul). The iris (the colored part of the eye) controls how much light the pupil lets in.
Detailed explanation-2: -Iris regulates the amount of light entering the eye by adjusting its size. Iris is a thin membrane, which controls pupil which in turn regulates the amount of light entering the eye.
