Here is a brief but comprehensive tour of the physiology of vision, guided by one of the grand masters of the discipline. Offering first a solid grounding in structure and function, the book emphasizes those areas that the author considers to be of most significance in current research. Much attention is given to the role of vision in circadian timekeeping, the development of the visual system, the effect of aging on the eye, and the provocative questions of perception and illusion.

An eminently readable text, Focus on Vision will more than satisfy the needs of students in ophthalmology, optometry, physiological optics, biology, psychology, and art. It is fully illustrated and contains lists of references and further reading. The questions at the end of each chapter may be used to test understanding or simply to excite discussion.
