Do you know what to do if you get sand in your eye? What if someone accidently elbows you in the eye during the game? Here are tips for dealing with some of the most common eye injuries. Remember to act fast and get help from an adult.
If particles, like sand or dust, get into your eyes, don’t rub! Wash your eyes out with waterIf you get hit in the eye with a ball, rock, or elbow, gently put a cold compress on your eye for 15 minutes. This should make the swelling go down and relieve the pain. Have an adult take you to the doctor.
If a chemical from a class experiment, cleaning fluid, or battery acid splashes in your eye, wash your eye out with water for at least 10 minutes. Have an adult take you to the doctor immediately.
If an object like a stick or pencil gets stuck in your eye, don’t pull it out. This is very serious. Have an adult put a loose bandage on your eye. Don’t put any pressure on the object. Have an adult take you to the doctor immediately.

Macula (MACK-yoo-luh) is the small, sensitive area of the retina needed for central vision. It contains the fovea.

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 is the colored part of the eye. It regulates the amount of light entering the eye through the 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 (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 (SKLEH-ruh) is the white outer coating of the eye.

Vitreous humor (VIT-ree-us HYOO-mer) is the clear gel that fills the inside of the eye.

Fovea (FOH-vee-uh) is the center of the macula, where your vision is sharpest.

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 (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.
