Written by one of the pioneers in visual perception, Seeing provides an overview of the basics of sight, from the anatomy of the eye, to optical illusions, to the way neural systems process visual signs. To help readers better appreciate the most-used of our five senses, Tom Cornsweet describes the early physical and physiological processes that occur in human vision in relation to the forces of evolution. He also includes answers to common questions about vision—including those that many of us ask during a visit to an eye doctor—to illustrate how the study of vision can provide a better understanding of one's everyday relationship with sight.
