Abstract

Here is a curious admixture of complex mathematical optics and sound refractive common sense. The author admits that the origin of the book lay in an endeavor to write an article on the why and wherefore of the change in the refractive strength of an ophthalmic lens on moving it forward from the eye. The elucidation of the subject led him far afield from the original object and there resulted page upon page of mathematical formulas that are beyond the comprehension of the average ophthalmologist. The phraseology employed is none too happy, as may be exemplified in the second sentence of the book, which occupies twenty-five lines and contains forty— one commas, one colon, one semicolon, five parentheses, four i. e.'s and one final period. After ninety-six pages of formulas dealing with the laws of refraction and the optical constants of the eye, he proceeds to discuss the mechanism of
