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
