Eye Anatomy

Iris: Pigmented tissue behind the cornea that gives color to the eye and also controls the amount of light entering the eye by varying the size of the pupil. The iris separates the anterior chamber of the eye from the posterior chamber.

Cornea: Transparent front tissue that covers the iris, pupil and anterior chamber and acts as a lens to focus light on the back of the eye. The cornea provides most of the eye's optical power.

Pupil: Opening at the center of the iris that appears as a black circle and controls the amount of light that enters the eye.

Lens: Transparent tissue that is present behind the iris and acts to focus light at the back of the eye. The lens plays a role in helping your eyes focus at near when reading.

Ciliary Body: a muscular ring under the surface of the eyeball; helps the eye focus by changing the len’s shape and also produces aqueous humor.

Choroid: the vascular layer between the sclera and the retina; the blood vessels in the choroid help provide oxygen and nutrients to the eye.

Optic Nerve: Largest sensory nerve of the eye; carries impulses for sight from retina to brain.

Macula: Small, specialized central area of the retina responsible for acute central vision.

Retina: Part of the eye that converts images into electrical impulses sent along the optic nerve for transmission back to the brain. Consists of many named layers that include rods and cones.

Vitreous: Transparent, colorless, gelatinous mass; fills rear two-thirds of the interior of the eyeball, between the lens and the retina.
