This work is intended to complement a standard text on visual perception with knowledge of the essential features of oculomotor systems and their bearing on visual perception. These issues, however, have useful implications for students in a number of disciplines such as psychology, biomedical engineering, human factors, optometry, ophthalmology, and artificial intelligence. Accordingly, the work is structured to be complete in itself and may be read on its own. Students not trained in optics or the vision-health disciplines also may find useful the Appendix on common visual anomalies as well as Chapter 2 on central concepts of physiological optics.

I have tried, throughout, to be mindful of historical and philosophy of science issues so that the myriad facts associated with the intersection of perception and eye movement systems may derive extended meaning by being seen in an appropriately broad context. My hope, of course, is that in so doing, reading the text proves to be both a useful and an enjoyable intellectual exercise.
