Little eyes
Your eyes are amazing. Let's have a look.
Your eye
Tap a yellow dot. Or tap a word.
Cornea. The clear window at the front. Light comes in here.
The dotted orange lines are light. They bend at the front and meet at the back.

Your brain makes the picture. Your eyes send it the light.
Make the room change
Tap a button. The room changes. Your eyes do not.
Some people see the room like this all the time. Glasses help some people. Being kind helps everyone.
The eye doctor
An eye doctor is called an optometrist. Say it: op-TOM-e-trist. They look at your eyes with a little light. It does not hurt. You might get to wear funny glasses with lenses which click in. Sometimes you get drops which make the room look bright for a while.
Going to the optometrist is free for children.
Glasses are brilliant
Glasses help eyes see clearly. Some friends wear a patch for a while. That helps one eye get stronger. Never laugh at glasses or a patch. They are tools, like a bike helmet.
