    What you’ll learn to do

    Explain the process of vision and how people see color and depth

    Several photographs of peoples’ eyes are shown.

    The visual system constructs a mental representation of the world around us. This contributes to our ability to successfully navigate through physical space and interact with important individuals and objects in our environments. This section will provide an overview of the basic anatomy and function of the visual system. In addition, you’ll explore our ability to perceive color and depth.

    Learning Objectives
    • Describe the basic anatomy of the visual system
    • Describe how light waves enable vision
    • Describe the trichromatic theory of color vision and the opponent-process theory
    • Describe how monocular and binocular cues are used in the perception of depth
