Eyes on the World

Your eyes are your windows to the world. Every day, they take in information, or facts, about light, color, shape, movement, and the distance of things around you. Then the eyes send this information to the brain. As part of the body’s sensory system, the eyes work with the brain to give you your sense of sight.

The eye is an organ made up of three main layers. The outer layer consists of the cornea and sclera. The iris, lens, and ciliary muscle make up the middle layer. Finally, the retina and optic nerve make up the inner layer of the eye.

This picture shows only some of the parts of the eye. There are millions of parts that help the eye do its job.View Larger Image
