Publisher's Synopsis
Refraction And How To Refract is a comprehensive guide to the science of optics and the art of refracting, written by James Thorington and originally published in 1904. This book covers a wide range of topics related to vision and eye care, including the principles of light and optics, the anatomy and physiology of the eye, the use of retinoscopy to measure refractive error, and the fitting of spectacles and eyeglasses to correct vision problems.The book is divided into several sections, each of which provides detailed information on a specific aspect of refracting. The first section covers the basics of optics, including the properties of light, the laws of reflection and refraction, and the construction of lenses and prisms. The second section focuses on the anatomy and physiology of the eye, explaining how the eye works and how it processes visual information.The third section of the book is devoted to retinoscopy, a technique used to measure refractive error by observing the movement of light reflected from the retina. This section provides detailed instructions on how to perform retinoscopy and interpret the results.The fourth and final section of the book covers the fitting of spectacles and eyeglasses, including the selection of appropriate lenses, the measurement of pupillary distance, and the adjustment of frames for comfort and fit.Overall, Refraction And How To Refract is a valuable resource for anyone interested in the science of optics and the art of refracting, whether they are eye care professionals or simply curious about the workings of the human eye.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
