The eye is amazing! It helps us see by bending light, a process called refraction. Let's break down how it all works.

First, light waves come into our eyes through the cornea. The cornea is the clear outer part of the eye. When light hits this curved surface, it bends because the air and cornea are different in density. This bending helps focus the light onto the retina, which is at the back of the eye.

Next up is the lens. The lens helps to focus the light even more. It can change shape with the help of tiny muscles called ciliary muscles. This change lets us see things that are close by and far away. This ability to adjust focus is called accommodation.

When the light reaches the retina, special cells called photoreceptors change the light into electrical signals. This step is super important because our brain needs these signals to figure out what we are looking at. The signals travel through the optic nerve to the brain, where they create the images we see.

To sum it up:

• Cornea: This part bends the light first.
• Lens: It fine-tunes the focus and helps us see at different distances.
• Retina: It changes light into electrical signals.
• Brain: It interprets these signals into the pictures we see.

All these parts work together to turn light waves into the colorful sights of our world. Each step shows how light and different parts of our eyes work together to help us see.
