This book, which is a comprehensive manual on the natural care of the eye, starts from the concept that eyesight is intricately connected to the mind and explains how good habits of eye care and mental relaxation can keep the eyes rested and refreshed. It then suggests simple but effective exercises to improve eyesight and treat various eye disorders. There are also chapters on the discoveries of Dr W. H. Bates and the physiology of the eye, as well as case histories, question-and-answer sections, and some letters by Sri Aurobindo on eyesight and yogic vision.
