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.

Clinical Optics is intended primarily for use by optometry students, though it could also prove useful for the training of optometric technicians and dispensing opticians. This book is organized into thirteen chapters. These chapters cover most aspects of ophthalmic optics or clinical optics including the design and dispensing of eyewear, the types for lenses suitable for correcting high refractive errors, the optical principles governing low vision lenses and the importance of absorptive lenses and lens coatings for eye protection against radiation. This book will be of interest to optometry students and to those involved in the training of optometric technicians and dispensing opticians.

A COMPREHENSIVE, LEARNER-FRIENDLY INTRODUCTION TO CLINICAL OPTICS Geometrical and Visual Optics, Second Edition is a rigorous, yet highly accessible text that expertly combines basic optics with clinical applications in a way that brings key optometry topics to life. It emphasizes a vergence approach to geometrical and visual optics, reinforcing its fundamental utility in clinical practice. Featuring an open, workbook-style design, the book avoids unnecessary math and focuses on those optical concepts and problem-solving skills that are the cornerstones of contemporary clinical eye care. If you are an optometry student who wants to gain a complete, intuitive understanding of geometrical and visual optics, Geometrical and Visual Optics belongs on your reference shelf. FEATURES In-depth coverage of geometrical and visual optics spans the full spectrum of topics, from refraction at spherical surfaces, to thin and thick lenses, to depth of field, ametropia, magnification, retinal image size, and reflection Focus on the vergence approach provides a conceptual paradigm for the book and underscores its strategic application in clinical practice Valuable chapter on basic terms and concepts reviews light sources, rays, and pencils; vergence; and refraction and Snell's law Primary emphasis on core concepts, with a minimum of formulae and superfluous mathematics Chapter-ending self-assessment problems of varying complexity--with worked-out answers--and two comprehensive practice examinations with answers Exceptional pedagogy, including concept-clarifying figures and chapter summaries with key formulae PRAISE FOR DR. STEVEN SCHWARTZ: Like his popular book, Visual Perception: A Clinical Orientation, Dr. Schwartz offers a foundational optics text for eye care professionals in training and those seeking a concise review. Dr. Schwartz's contributions to our collective success remain unmatched. -- Jeff Rabin, Optometry and Vision Science
