Paperback. Etat : New. Print on Demand. A guide for general practitioners, this book focuses on determining if a patient requires glasses, either to aid their vision or to relieve symptoms not directly related to the eyes. The author begins by outlining the history of test-type arrangement as a scientific test of visual power and discussing how the invention of the ophthalmoscope made it possible to measure the refraction of the eye. The book provides the reader with a classification of conditions requiring glasses, separating them into presbyopia, hyperopia, myopia, and asthenopia, and explaining each subject in straightforward and simple terms. The author also provides a guide for adjusting glasses for presbyopia, along with helpful examples for correcting presbyopia, myopia, and hypermetropia.
