Anatomy of an Eye
Courtesy: National Eye Institute, National Institutes of Health
Cornea - The clear outer part of the eye's focusing system located at the front of the eye.
Fovea - The center of the macula that gives the sharpest vision.
Iris - The colored part of the eye that regulates the amount of light entering the eye.
Lens - A clear part of the eye behind the iris that helps to focus light, or an image, on the retina.
Macula - A small, sensitive area of the retina that gives central vision. It is located in the center of the retina and contains the fovea.
Optic Nerve - A bundle of more than one million nerve fibers that carries visual messages from the retina to the brain.
Pupil - The opening at the center of the iris. The iris adjusts the size of the pupil and controls the amount of light that can enter the eye.
Retina - The light-sensitive tissue lining at the back of the eye. The retina converts light into electrical impulses that are sent to the brain through the optic nerve.
Vitreous Gel - A clear gel that fills the inside of the eye.
