William Horatio Bates provides an alternative look at the study of the eye. He does not deny that there are certain visual defects people experience; however, he does deny that glasses are the one and only solution. Instead, Bates' studies have led him to believe that simple muscle relaxation could relieve the strain that is the cause of most eye problems. This idea is now referred to as the Bates Method. This book is still consulted today by people seeking alternative solutions to their vision issues.
