Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 edition. Excerpt: ...the retinal image depends upon two factors: (1) the visual angle subtended by the object; (2) the distance between the second nodal point and the retina ((?2). If the visual angle be kept constant and minimal, the retinal image, and therefore the visual acuity, will vary directly as the distance between the second nodal point and the retina. If we replace d in equations (9), p. 70, by F' + y, where y is the variable distance of the correcting lens from the anterior focal plane of the eye, we have (remembering that F = F = F', say) By (1), p. 87, the distance of the retina from the posterior focus of the emmetropic eye = x = .pit-nil r-.r'F.-.Fp.. (9). That is, the uncorrected hypermetropic eye has smaller, and the uncorrected myopic eye has larger, retinal images than the emmetropic eye. We must now consider the effect of accommodation upon the images. The optical effect of accommodation is to increase the distance between the second nodal point and the retina. Hence, accommodation is accompanied by increase in the size of the retinal image. The relative visual acuity, or visual acuity for near objects, is therefore greater than the absolute visual acuity, or acuity for distant objects. This accounts in large measure for the difficulty in relaxing the accommodation in ophthalmoscopic examination by the direct method. The uncorrected hypermetropic eye has smaller retinal images than the emmetropic eye; these are increased beyond the size of the emmetropic images by a correcting lens outside the anterior focal plane of the eye. Similarly the correction of presbyopia also results in the production of larger images. The uncorrected myopic eye has larger retinal images than the emmetropic eye; these are made smaller than the...

Book excerpt: Excerpt from Elementary Ophthalmic Optics: Including Ophthalmoscopy Retinoscopy This book is intended to supply the student of ophthalmology with all the optics which is necessary for an intelligent knowledge of his subject. The proofs are in some cases a little confusing at first reading, but they never demand more than a very elementary acquaintance with mathematics. Even where a trigonometrical nomenclature has been inevitable the meaning of the signs is usually self-evident. Special care has been taken to emphasise all important propositions by italics, so that those who do not care to grapple with the proofs are provided with a readily accessible synopsis of results. A short bibliography of the best books upon the subject has been added, so that the advanced student may know where to look for further information. It is hoped that the book will prove a useful addendum to such practical works as Morton's Refraction of the Eye, Hartridge's Refraction, etc. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Elementary Ophthalmic Optics The aim of this book is to set forth, in a clear and simple manner, those portions of Physical and Geometrical Optics which I consider essential to the medical student beginning his Ophthalmic studies. No one recognizes more fully than I do that the proper province of the ophthalmic surgeon is to treat diseases of the eye; but in order that he may do so with success it is necessary that he should have a competent knowledge of the organ of vision from a physical stand-point. It is hoped that this small manual will form a suitable and easy introduction to such knowledge. The subject of Physiological Optics is not discussed, since that branch of ophthalmic study is, as a rule, sufficiently explained in text-books dealing with diseases of the eye. My endeavour has been to give in one volume all the information necessary for the beginner, and therefore I have placed in the introduction those parts of plane trigonometry which he requires.
