ABSTRACT

The third edition of this useful little volume, in which a new format appears, extends Thorington's contributions to the subject over a period of forty years. As in the previous editions, important contributions are the simplicity and lucidness with which the subject is treated and the freedom from advanced mathematical formulas, which only confuse the beginner. Sections on the muscular insufficiencies and orthoptic training have been added, and, while these are not extensive, they give the important facts. A few typographical errors occur, such as the spelling of color on page 31 and the notation on page 118 that vision of the 60 line at 6 meters is recorded 4/60. This edition is accepted as one of the notable works in the introduction to refraction of the eye.
