Anatomy of the Eye

Cornea: The transparent outer layer of the eye that covers the iris and pupil.

Aqueous: The liquid that fills the space between the cornea and the iris.

Iris: The round, colored membrane between the cornea and the lens that surrounds the pupil.

Lens: The transparent tissue located between the iris and vitreous that focuses light entering the pupil into the retina.

Pupil: The small, dark round opening in the center of the eye’s iris through which light enters the eye.

Vitreous: The gel that fills the space between the iris and the retina.

Retina: A layer of nerve cells lining the back of the eye that detects light and color information.

Optic Nerve: The nerve which transmits signals from the retina to the brain to be processed as vision.
