VOL. I.
By C.H. Brown, M.D.
Graduate University of Pennsylvania; Professor of Optics and Refraction; formerly Physician in Philadelphia Hospital; Member of Philadelphia County, Pennsylvania State and American Medical Societies.
The Optician's Manual, Vol. I., has proved to be the most popular work on practical refraction ever published. The knowledge it contains has been more effective in building up the optical profession than any other educational factor. A study of it is essential to an intelligent appreciation of Vol. II., for it lays the foundation structure of all optical knowledge, as the titles of its ten chapters show:
| Chapter I. | —Introductory Remarks. |
| Chapter II. | —The Eye Anatomically. |
| Chapter III. | —The Eye Optically; or, The Physiology of Vision. |
| Chapter IV. | —Optics. |
| Chapter V. | —Lenses. |
| Chapter VI. | —Numbering of Lenses. |
| Chapter VII. | —The Use and Value of Glasses. |
| Chapter VIII. | —Outfit Required. |
| Chapter IX. | —Method of Examination. |
| Chapter X. | —Presbyopia. |
The Optician's Manual, Vol. I., is complete in itself, and has been the entire optical education of many successful opticians. For student and teacher it is the best treatise of its kind, being simple in style, accurate in statement and comprehensive in its treatment of refractive procedure and problems. It merits the place of honor beside Vol. II. in every optical library.
