Vision and Perception

The vision process is complex. All vision is based on light that enters the eye, and the properties of the visible spectrum of light that humans perceive includes wavelength, which is experienced as color, and amplitude, which is experienced as brightness or intensity of light. In addition, the eye is comprised of many different parts that work together to create visual information that is processed in the brain.
