The Manual of Refraction is designed to reach the most uninitiated office assistant and orthoptic technician and the most elementary student as well as the physician with many years of experience.
The manual is designed as an essentially practical guide to all aspects of contact lens fitting.
This book has been written as a successor to H.H. Emsley's Visual Optics. Its aim is to provide an up-to-date text on ocular dioptrics, the various subjective and objective techniques of refraction, and the optical instruments used in the examination of the eye.
This book describes all aspects of this process in a logical sequence, although since it is aimed at student and practising optometrists, it emphasizes the role of the optometrist in delivering this service.
