About the Eye – For Kids
Macula
(MACK-yoo-luh) is the small, sensitive area of the retina needed for central vision. It contains the fovea.
Lens
Lens is the clear part of the eye behind the iris that helps to focus light on the retina. It allows the eye to focus on both far and near objects.
Iris
Iris is the colored part of the eye. It regulates the amount of light entering the eye through the pupil.
Pupil
Pupil (PYOO-pul) is 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.
Cornea
Cornea (KOR-nee-uh) is the clear dome covering the front of your eye. It helps your eye focus light so things look sharp and clear.
Sclera
Sclera (SKLEH-ruh) is the white outer coating of the eye.
Vitreous humor
Vitreous humor (VIT-ree-us HYOO-mer) is the clear gel that fills the inside of the eye.
Fovea
Fovea (FOH-vee-uh) is the center of the macula, where your vision is sharpest.
Optic nerve
Optic nerve (OP-tic nurv) is the bundle of more than 1 million nerve fibers that carry visual messages from the retina to the brain.
Retina
Retina (REH-tin-uh) is the light-sensitive tissue lining the back of the eyeball. It sends electrical impulses through the optic nerve to the brain.
