Anatomy of the Eye

How the Eye works

The eye is like a camera. When you take a picture, the lens in front of the camera allows light through and focuses the light on the film that covers the back inside wall of the camera. When the light hits the film the picture is taken. The eye works in much the same way.
The front parts of the eye are clear so the light can pass through to the center of the eye called the vitreous cavity. The vitreous cavity is filled with a clear, jelly-like substance called the Vitreous. The cornea focuses the light and the lens on to a thin layer of tissue called the Retina, which covers the back inside wall of the eye. When the focused light hits the Retina, a picture is taken. Messages about this picture are sent to the brain through the optic nerve. The brain intercepts this message and this is how we see
