The Human Eye – Nature's Camera

The human eye is one of the most amazing organs in our body. It helps us to see light, color, and shapes, and sends messages to the brain to understand what we are looking at.

Parts of the Human Eye:

Cornea: The clear outer layer that helps to focus light entering the eye.

Pupil: The black circular opening in the center of the eye that changes size to control how much light enters.

Iris: The colorful part around the pupil that adjusts its size — like a camera lens!

Lens: Focuses light rays onto the retina.

Retina: A thin layer at the back of the eye that changes light into electrical signals.

Optic Nerve: Carries those signals to the brain, where the image is formed.

How the Eye Works:

When you look at something — like a tree — light from that tree enters your eye through the cornea and pupil, passes through the lens, and lands on the retina. The retina turns this light into signals and sends them to your brain via the optic nerve. Your brain flips and interprets these signals — that's how you see the tree clearly!
