The eyeball is the organ of sight in human beings. An opaque, tough, protective layer referred to as the sclera, or white of the eye, covers the outer surface of the eyeball. Anteriorly, a transparent, dome-shaped structure called the cornea allows light to pass into the interior of the eye. Underneath the cornea is a compartment referred to as the anterior chamber. The anterior chamber contains the pigmented iris and its circularly shaped aperture, the pupil. Below the iris is another chamber, called the posterior chamber, which extends from base of the iris to the biconvex, transparent lens that is suspended behind it. A light sensitive layer referred to as the retina, covers the inner surface of the eye. The retina receives images focused onto it by the lens and transmits them via the optic nerve to the brain.
