The transparent, dome-shaped surface that covers the front of the eye. It helps focus light as it enters the eye and provides most of the eye’s optical power.

The colored part of the eye that surrounds the pupil. It controls the size of the pupil and, consequently, the amount of light that enters the eye by adjusting its diameter

The black, central opening of the iris that allows light to enter the eye. Its size adjusts in response to light conditions to regulate the amount of light entering the eye.

Located behind the iris and pupil, it focuses light onto the retina. It changes shape (accommodates) to adjust for near or distant vision.
