Publisher's Synopsis
Excerpt from Ophthalmic Lenses and Prisms an Essay Contributed to the American Encyclopedia of Ophthalmology
The purpose of this essay is to describe the physical characteristics of ophthalmic lenses and prisms, and to lay before the student of ophthalmology at. Least those fundamental principles of their refrac tion with which every efficient eye - practitioner should be familiar; especially as the adaptation of lenses to vision is founded upon that commensurate knowledge of theoretic Optics which embraces the meas urable phenomena of light acted upon by mirrors, lenses and prisms. In other words, this unique branch of applied science is a special department of physics with which even the university student is not generally made familiar.
