Treatise on Physiological Optics


Book Description

The most important work ever produced in the field of physiological optics, this classic is a model of scientific method and logical procedure, and it remains unmatched in its thorough and accessible approach. This is the second in a three-volume republication of the definitive English translation of Handbuch der Physiologischen Optik, originally published by The Optical Society of America in 1924 and containing everything that was known about physiological optics up until that time. The substratum consists of the data that Helmholtz furnished in the two nineteenth-century German editions that appeared during his lifetime. These volumes also contain extensive supplementary matter that Nagel, Gullstrand, and Kries incorporated in the third German edition of 1911, as well as significant new material prepared for the 1924 English translation by C. Ladd-Franklin, Gullstrand, and Kries, with copious annotations by James P. C. Southall that brought the work up to date with current research. The first volume in this series explores the dioptrics of the eye; Volume II examines the sensations of vision, including stimulation by light; simple and compound colors; intensity and duration of sensation of light; and variations of sensitivity and contrast. Appendixes cover later findings on adaptation, twilight vision, and the duplicity theory; normal and anomalous color systems and theories of vision; and the nature of color sensations. The succeeding volume considers perceptions of vision.

Optics, Retinoscopy, and Refractometry


Book Description

Optics, Retinoscopy, and Refractometry, Second Edition is a valuable and up-to-date reference that allows the reader to better understand and measure the patient's refractive error. Information is presented on each of the three important topics in an easy-to-read format. Al Lens, COMT begins Optics, Retinoscopy, and Refractometry with a focus on the basics of optics, providing the foundation for understanding retinoscopy. The detailed instructions and practical exercises help the beginning technician become proficient at the valuable skill of retinoscopy. This comprehensive resource concludes with a simplified approach to refractometry, including a section on refractive surgery from an optics perspective. New to this edition: A section on refractive surgery from an optical point of view. Discussion on wavefront technology. Updated text and diagrams. Features: Study icons throughout the text. Appendices containing data on the metric system, units of measurement, metric conversions, and abbreviations. Refractometry exercises. Whether you are a beginning technician looking for a basic overview or an experienced examiner in search of a clear-cut review, Optics, Retinoscopy, and Refractometry, Second Edition will suit all your optics needs.
