How The Eye Works

The healthy eye works very much like a camera. Light passes through a series of lenses in the front of the camera, focusing on the film in the back of the camera. In the eye, light passes through the cornea, lens, and vitreous gel, ultimately focusing on the retina which works like the film in a camera. Information gathered by the retina is then sent to the brain via the optic nerve.
