A basic optics textbook that integrates relevant visual and ophthalmic optics material with basic geometric and physical optics. Dr. Keating's book uses the vergence approach to optics as well as the wavefront approach to vergence as an aid to developing optics intuition.

The acclaimed introductory text to geometrical and visual optics --- now in full color Doody's Core Titles for 2021! Geometrical and Visual Optics, Third Edition is a rigorous, yet approachable text that expertly combines basic optics with clinical application in a way that brings key optometry topics to life. It is meant to be a concise and user-friendly resource for clinicians as they begin their study of optics, and as they eventually prepare for licensing examinations. The book emphasizes optical concepts and problem-solving skills that underlie contemporary clinical eye care, and because of its clinical utility, a vergence approach is stressed. FEATURES: 3 complete practice exams, totaling 122 questions 200+ end-of-chapter self-assessment problems with detailed worked-out solutions Full-color figures and clinical highlights Learning Objectives appear at the beginning of each chapter Color highlighted summaries, sample problems, and tables Summary and list of formulas appear at the end of each chapter NEW CHAPTER on lens thickness; and prism coverage has been expanded to include vertical imbalance 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 Primary emphasis is on core concepts, with a minimum of formulas and superfluous mathematics

Among the features of this student-friendly textbook are: Self-assessment questions at the end of every chapter. Comprehensive practice examinations. Workbook-style approach teaches students a problem-solving methodology, avoids unnecesary mathematics.

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

Provides comprehensive coverage of Visual Optics - the field of optics as applied to the function of the eye. The book presents the necessary concepts and definitions that explain retinal image properties, including aspects such as visual acuity and colour perception.

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.

Optical imaging starts with geometrical optics, and ray tracing lies at its forefront. This book starts with Fermat’s principle and derives the three laws of geometrical optics from it. After discussing imaging by refracting and reflecting systems, paraxial ray tracing is used to determine the size of imaging elements and obscuration in mirror systems. Stops, pupils, radiometry, and optical instruments are also discussed. The chromatic and monochromatic aberrations are addressed in detail, followed by spot sizes and spot diagrams of aberrated images of point objects. Each chapter ends with a summary and a set of problems. The book ends with an epilogue that summarizes the imaging process and outlines the next steps within and beyond geometrical optics.
