'Combines academic depth with clear clinical explanation; still the best visual optics textbook around' - Professor Roger Anderson, Vision Science, University of Ulster. 'Essential reading for all those interested in the optics of the eye and the measurement of vision and ocular characteristics' - Dr Colin Fowler, Optometry & Vision Sciences, Aston University. "'Bennett & Rabbetts"' clinical visual optics cleverly explores and combines the founding principles, clinical relevance and some more advanced aspects of optical techniques, instrumentation and applications in a unique and thought-provoking manner. An invaluable resource to the student, practitioner and clinical visual scientist alike' - Dr James Loughnan, Optometry, Dublin Institute of Technology. 'Numerous clinical anecdotes bridge the gap between theory and practice, resulting in a text which will be an invaluable guide to students of optometry, researchers and practitioners alike' - Dr Robert Cubbidge, Optometry & Vision Sciences, Aston University. The fourth edition of this classic textbook has been brought thoroughly up to date with revised chapters on Ocular Aberrations, Visual Examination of the Eye, and Distribution and Ocular Dioptics of Ametropia. New contributors have been added and the book has been completely redesigned using colour to offer a more accessible layout and enhance the many line illustrations. The new CD Rom has valuable additional resources including a simulation of subjective refraction, video clips showing clinical procedures and extra appendices to the book. This comprehensive review of optics of the human eye covers: refractive correction and the instruments used in: eye examination, measurement of visual acuity, contrast sensitivity, refractive errors, accommodation and binocular vision; the side effects of spectacle and contact lens corrections; the oculo-motor system and stereopsis providing a firm foundation for further study; the dioptics of the eye, including its aberrations and schematic eyes; and thorough theoretical chapters and clinical chapters that contribute a fundamental understanding of the procedures, together with sound practical advice. The new edition of "Clinical Visual Optics" will be invaluable to all those studying optometry, dispensing optics and physiological optics. The depth of coverage will make it a prime source of information for the qualified practitioner or a prospective researcher in these fields.
