A K Khurana Theory and Practice of Optics and Refraction

Theory and Practice of Optics and Refraction

The Essential Guide for Mastering Clinical Refraction and Optical Modalities

Theory and Practice of Optics and Refraction serves as a fundamental resource for understanding the basic principles of light and optics essential to learn the art of refraction. This Fifth Edition has been updated to provide basic principles and the recent advances in the field of optics and modalities of correcting refractive errors. Since the invention of eyeglasses, efforts have been made to improve their profile as well as the technique of prescribing, and still the refraction continues to form the bread and butter for ophthalmologists as well as the optometrists. An effort has been made to skillfully intermingle these two essential ingredients to the advantage of readers, and a detailed coverage has been given to the clinical refraction, i.e., determination of the errors of refraction.
