Vision

The visual system constructs a mental representation of the world around us (Figure). 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, we will explore our ability to perceive color and depth.

Several photographs of peoples’ eyes are shown.
Our eyes take in sensory information that helps us understand the world around us.
