Parts of the Eye
Vitreous Gel: A clear gel that fills the inside of the eye.
Optic Nerve: A bundle of more than one million nerve fibers that carries visual messages from the retina to the brain.
Macula: The small sensitive area of the retina that gives central vision. It is located in the center of the retina and contains the fovea.
Fovea: The center of the macula and gives the sharpest vision.
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.
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.
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.
