👀 Your Eyes

Your eyes help your body by seeing the colors, shapes, and people around you.

🔬 How Your Eyes Work

Light enters your eye through the dark circle in the middle, called the pupil. The colored part around it, the iris, makes the pupil bigger in the dark and smaller in bright light. A clear lens behind the pupil focuses the light onto the retina at the back of your eye, and the retina sends signals along the optic nerve to your brain, which turns them into the picture you see.

💚 Taking Care of Your Eyes

Never look straight at the Sun, even with sunglasses, because it can damage your eyes. Take breaks from screens by looking at something far away every 20 minutes, and spend time playing outside. If words on the board look blurry, tell a grown-up, because an eye doctor can check whether you need glasses.

Compare how well you can see in a bright room versus a dark room, and talk about why eyes need light to see clearly.
