Practical Aspects of Ophthalmic Optics, 4th Ed. Margaret Dowaliby. Boston: Butterworth-Heinemann, 2000. Pages: 250. Price: 47. 50. ISBN 0-7506-7189-0. This book provides the reader with a very comprehensive understanding of the mathematical formulas and reasons required to solve basic and complex prescription requirements of the patient. There are many lens types and manufacturers from which the practitioner can select lenses, and the author makes an earnest attempt to provide the reader with a history of the different lens types that are available today, from the most common ophthalmic lens designs to the much older misunderstood designs. This history of ophthalmic lens design also enables the reader to understand the application and complications that may be associated with the use of such lenses, which facilitates in the selection of these products. In addition, the author also takes the reader through the thought process of lens selection and recommended fitting requirements of the spectacle solution for the wearer. Practical Aspects of Ophthalmic Optics would be a valuable resource for the practitioner who may not be familiar with the application of earlier lens designs and a great tool for the low-vision spectacle specialist because of its in-depth look at specialty ophthalmic lenses.
