How does the human eye convert light into images?

The human eye turns light into pictures by using special parts inside it, kind of like a camera.

Light goes through a clear window at the front of your eye called the cornea. It then passes through a round opening called the pupil, which acts like the shutter on a camera, letting in just the right amount of light. A muscle called the iris controls how big or small this opening is, like adjusting the size of a door to let more or less people in.

Once inside, the light hits a curved mirror called the lens. This lens bends the light and focuses it onto a screen at the back of your eye, the retina. The retina is covered with tiny light-sensitive cells called photoreceptors, which are like little detectives that catch the light. These cells send messages through wires (called nerves) to your brain, where they become pictures you can see!

It’s like when you look at a painting, the colors and shapes come together in your head to make something beautiful.
