ANATOMY OF THE EYE
Your eyes are made up of many intricate parts that each play a role in helping you see. Learn the basics of eye anatomy and the specific purpose of each part:
Sclera
The protective outer coating of the eyeball, which appears white, and is mostly opaque.
Cornea
The clear front of the sclera, where light travels into the eye
Conjunctiva
The delicate membrane for protection in the front of the eye and inside its lid
Iris
Gives eyes their color and is equipped with tiny muscles to expand or contract the pupil to manage incoming light
Pupil
The small black spot in the center of the iris which allows light to enter the eye
Retina
The layer of tissue with receptor cells that send messages to the brain through the optic nerve
Lens
The flexible tissue behind the iris and pupil that focuses light on the retina
Macula
The area in the center of the retina made up of several tiny cells to help the lens focus light and help with tasks requiring precision
Aqueous Humor and Vitreous Humor
The gel-like fluids inside the eyeball that help give them shape
