Based on the Bates Method, an integrative approach to natural vision improvement, this work presents a major reexamination and expansion of Bates’ original principles. The author offers a thorough discussion of the principles of vision, identifies the basic habits of clear vision, and covers anatomy, physiology, and prescriptions. The author emphasizes that relearning to see involves integrating and maintaining left- and right-brain and mind-body habits of clear vision throughout the day. He argues that poor vision can be improved, that sight need not deteriorate with age, and that blurry vision is not absolutely hereditary. He shows how healthy vision habits, based on relaxation of body and mind, are the key to good eyesight.
