Detailed explanation-1: -The cornea is the transparent front part of the eye that covers the iris, pupil and other parts of the eye.
Detailed explanation-2: -The transparent cornea forms the anterior portion of the outer casing of the eye and has the dual functions of protecting the inner contents of the eye as well as providing about two thirds of the eye’s refractive power.
Detailed explanation-3: -First, light passes through the cornea (the clear front layer of the eye). 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.
