The acclaimed introductory text to geometrical and visual optics --- now in full colorDoody's Core Titles for 2022!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 questions200+ end-of-chapter self-assessment problems with detailed worked-out solutionsFull-color figures and clinical highlightsLearning Objectives appear at the beginning of each chapterColor highlighted summaries, sample problems, and tablesSummary and list of formulas appear at the end of each chapterNEW CHAPTER on lens thickness; and prism coverage has been expanded to include vertical imbalanceIn-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 reflectionPrimary emphasis is on core concepts, with a minimum of formulas and superfluous mathematics
