The aim of this book is to provide an up-to-date text on ocular dioptrics, the various subjective techniques of refraction and the optical instruments used in the examination of the eye.

This revised edition now takes into account the latest research and instrumentation. The treatment of magnifiers now emphasizes the relationship with the user's eye. The Bennett-Rabbetts schematic eye, introduced in the last edition, has been adopted throughout.

It provides a comprehensive and clinically based guide to visual optics. With its suggested routines and numerous examples, this new book offers a straightforward "how to approach" to the understanding of clinical optics, refraction and contact lens optics. Designed for easy access, it presents information in a concise format that highlights key, need-to-know points. Part 1 addresses the basic visual optics of the eye along with emmetropia, ametropia and the correction of ametropia with spectacle lenses. Part 2 turns to the optics of contact lenses and the use of contact lenses in vision correction. Numerous worked examples based on real examination questions Practical and user friendly text Over 190 clear line diagrams An essential passport to examination success and a valuable quick reference for practitioners

The only text for optometric optics courses! This concise, reader-frie ndly, highly visual text covers key topics in geometrical and visual o ptics foundational in all optometry programs and the practice of optom etry. The book provides a valuable study for the NBED licensing examin ation in optometry. Featuring over 300 illustrations, this textbook co ntains numerous examples and problems, including self-assessment quest ions at the ends of chapters, with solutions in the back of the book.
