Specially written for students by authors with many years experience in teaching optics and dispensing, "Clinical Optics and Refraction" gives a concise view of the subject which avoids excessive emphasis on theory and instead concentrates on a practical and clinically based approach. With the requirements of UK optometry and dispensing optician syllabuses in mind, the authors give a clear account of the field of spectacle and contact lens optics in relation to the clinical context. The text contains numerous how-to-do-it worked examples, based on recent past examination questions, and many clear line illustrations to give students maximum help in understanding the practical issues in what can often be a challenging area of the curriculum. As well as being a must for optometry students and student dispensing opticians, "Clinical Optics and Refraction" will also be essential reading for qualified dispensing opticians entering training and practice as contact lens opticians. Practising optometrists will also find it invaluable as quick and accessible reference.
