Excerpt from The Principles of Refraction: In the Human Eye Based on the Laws of Conjugate Foci The conjugate focus is, of course, mentioned often in our treatises and text-books dealing with the optics of ophthalmology, but it is always in a subsidiary way and incidentally, and not as the bed rock upon which the whole fabric of refraction as it pertains to the formation of images rests.

Excerpt from The Principles of Refraction: In the Human Eye Based on the Laws of Conjugate Foci The conjugate focus is, of course, mentioned often in our treatises and text-books dealing with the optics of ophthalmology, but it is always in a subsidiary way and incidentally, and not as the bed rock upon which the whole fabric of refraction as it pertains to the formation of images rests. It has been borne in upon me, from a long experience in the teaching of medical students, that if we are able to seize and impress upon them some central fundamental law back to which all the phenomena involved can and must be referred for substantiation, we will have rendered their understanding much more logical and therefore easier. Such a fundamental law in refraction I consider the conjugate focus to be. Applied in this way we have found these laws to be of the greatest assistance in solving all the problems involved in the determination of the optical properties of the eye; but we believe they have a special value in unraveling the intricacies inherent in the complex optical system that lies at the basis of that method of examination known as skiascopy. Much of the confusion that prevails regarding the optical theory of that method is due to the neglect of a proper application of these laws to the requirements of this special case.
