This edition was written about seven years after the first. As some of the redundant matter has been eliminated, it is smaller than its predecessor. In the preface the author says that "whatever the type of book the would-be refractionist uses, it cannot be insisted upon too strongly that the art of refraction cannot in any sense be learned by reading." This booklet is divided into six sections and six appendixes, covering eyestrain, refraction, accommodation and convergence, the muscle balance, clinical methods of examination, and spectacles. Although the first edition attracted some unfavorable comment, it is believed that the second edition will redound to the credit of the author. He does not attempt to teach the beginner how to refract but rather counsels him in the art of refraction. Sound clinical advice is scattered throughout the pages, particularly with regard to the correction of lower errors of hypermetropia and astigmatism.
