EYE ANATOMY
HOW THE EYE WORKS
Cornea: Is the transparent front surface of the eye that allows light to travel through. It also provides most of the eye’s optical power.
Pupil: Is an opening in the center of the iris that regulates the amount of light that enters the eye.
Iris: Pigmented tissue behind the cornea which gives your eye color. It also contains muscles which control the size of the pupil regulating the amount of light entering the eye.
Lens: Transparent tissue that focuses light rays on the retina.
Retina: Part of the eye that converts light (what we see) into electrical impulses for the optic nerve to send to the brain. It contains 10 layers.
Macula: Small central area of the retina responsible for your central vision and the clarity in your vision.
Vitreous: Colorless, transparent, gelatinous fluid that fills the space between the lens and retina.
Optic Nerve: Largest bundle of nerve fibers of the eye. It carries electrical impulses to the brain.
Sclera: White part of the eye. It is a protective fibrous layer that covers the front of the eye, except for where the cornea is.
Ciliary Body: Ring of muscle in the eye that changes the shape of the lens to allow the eye to focus and creates aqueous humor.
Aqueous Humor: Clear fluid that fills the space between the cornea and the lens.
Choroid: Vascular layer of the eye between the sclera and retina. It contains blood vessels which provide oxygen and other nutrients to the eye.
