Here are descriptions of some of the main parts of the eye: Cornea: The cornea is the clear outer part of the eye’s focusing system located at the front of the eye. Iris: The iris is the colored part of the eye that regulates the amount of light entering the eye.
The eye is embryologically an extension of the central nervous system. It shares many common anatomical and physiological proper-ties with the brain. Both are protected by bony walls, have firm fibrous coverings and a dual blood supply to the essential nervous layer in the retina. The eye and brain have internal cav-

Parts of the eye. Cornea: The cornea is the clear, outer part of the eye’s focusing system located at the front of the eye. Iris: The iris is the colored part of the eye that surrounds the pupil. It regulates the amount of light that enters the eye.
Light goes through lens, which refracts light to retina. In low light tampetum reflects more light to retina. Rods use rhodopsin for light absorption; cones use photopsin for color absorption. Creates neurotransmission through chemical reaction from rhodopsin and photopsin to optic nerve.
