Book excerpt: Excerpt from Ocular Refraction and the Shadow Test This book is dedicated to the advancement of the science of optometry, and to those willing workers in the field who are ambitious for its advancement and who are laboring to that end. The correction of errors of refraction of the eye with lenses is a noble work, involving the betterment of conditions under which mankind is enabled to enjoy the most valuable of the five senses, viz., sight. Without glasses many would never know the beauties of our world, while others would suffer ceaseless misery. The resources of optical science have bean greatly improved, its practitioners have acquired more knowledge and skill, and its value is becoming more appreciated. The limit of the possibilities of the work have not been reached, however. and this should stimulate individual research and study. There arc rewards yet to be gained. If this book proves to be a help to any. and stimulates new thoughts and ideas, it will not have failed in its mission.

Book excerpt: Excerpt from Retinoscopy (or Shadow Test) In the Determination of Refraction at One Meter, Distance: With the Plane Mirror The proof of the growing popularity of Retinoscopy as the most valuable objective method of estimating the refraction of an eye is attested by the demand for another edition. The writer takes pleasure in carefully revising the work and bringing it up to date by the addition of new illustrations as well as illustrations of new apparatus. The author wishes to express his deep appreciation for the many favorable criticisms of the work and trusts that this edition may receive continued favor.

The optical explanation of the shadow-test, which would require illustrations for its elucidation, together with much theoretical and elementary detail, have been omitted with a view to make the book as practical as possible.

Book excerpt: Excerpt from Skiascopy a Treatise on the Shadow Test in Its Practical Application to the Work of Refraction: With an Explanation in Detail of the Optical Principles on Which the Science Is Based, With Sixty-Nine Illustrations and Four Plates The compilation of this volume was undertaken in response to a general demand on the part of oculists and Opticians for a work which would cover the subject more fully than any thus far published. Any treatise on skiascopy is obviously incomplete which merely describes the method of applying the shadow test without satisfactory explanation of the optical principles involved.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Eye, Its Refraction and Diseases: The Refraction and Functional Testing of the Eye, Complete in Itself, in Twenty-Eight Chapters With Numerous Explanatory Cuts and Diagrams The deductions of the various, formulae used in optics have been simplified and inserted. It is customary to omit the mathematics of the subject from treatises of this kind, but the author feels that the student should be familiar with the physics involved for the proper understanding of the subject. The scope of the work precludes as frequent reference to authors as the writer would like. The author feels that the new material and diagrams the work contains justifies its publication, so offers no apology for adding one more to the numerous books upon the same subject.

Download or read book The Functional Examination of the Eye Classic Reprint written by John Herbert Claiborne and published by Forgotten Books. This book was released on 2017-11-15 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Functional Examination of the Eye It is, indeed, difficult for any student to read the meagre descriptions of this examination that are found in text-books and retire with even a clear theoretical under standing of the subject. It is the purpose of the author to make the subject clear beyond peradventure for those who shall read these pages. It is his purpose, in short, to pre sent it in such a way that a student may follow the lines laid down and perform the examination with scientific and mechanical accuracy without further instruction. A fair success in teaching the subject for a number of years has led him to believe that he has won the right of presenting it. The ventilation of the subject of refraction, while it may be tedious, he believes to be essential for those who know little of the subject, or for those who have forgotten what they once knew. The author desires to call particular attention to the chapter on Presbyopia. To judge from the frequency with which glasses are prescribed for this condition by totally ignorant people, one might imagine it to be a very simple affair. As a matter of fact, it is the most difficult problem in refraction, and a thorough knowledge of it implies a thorough knowledge of all the anomalies of refraction.

This book was released on 2019-02-13 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Ophthalmic Record, Vol. 7: December, 1898 To see a thing you must get within seeing distance of it. A certain area cannot be perceived beyond a certain distance. The half-metre test types are very useful at the distance of a half metre or less, but they are of very little use at one metre, and quite worthless at two, four or six metres. In skiascopy there are movements of light and shadow in the pupil that can be seen at one-half metre, which are not to be seen at one metre or any greater distance and in many eyes it is these movements, and these alone, that truly indicate the refraction of the eye.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Refraction of the Eye: A Manual for Students I have found it necessary in several instances to repeat important matters, and this I have done to obviate the necessity of continual reference to other parts of the book, as well as in some cases to impress the importance of the subject upon the student. The woodcuts are numerous in proportion to the size of the work, but I consider that they are a very great help to the thorough understanding of the subject. The old measurements have been purposely omitted in favour of the almost universally adopted metrical system. It is confusing to the learner to have two distinct sets of measurements to deal with, and no possible good can accrue from perpetuating the old system of feet and inches. At the end of the work I have given a list of those authors to whom I have been indebted for much valuable information; and in conclusion, I take this opportunity of thanking my numerous friends for their help and suggestions.

Download or read book Retinoscopy written by James Thorington and published by Createspace Independent Publishing Platform. This book was released on 2018-04-15 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE author says in the preface to the fourth edition that "translations into French and German have been asked for and are in course of preparation," and I am glad to hear it; because, although the idea of retinoscopy had its birth in France and one of the best expositions of the principle (Fick) was written for Germans, yet both German and French literature is woefully deficient in the interest we show in refraction, and no student or practitioner, in either country, could have so clear, precise, or such a common sense guide to retinoscopy in all its details, as this little book of Thorington's. I say "little" intentionally, for it is not a large octavo, and has only 86 pages of type, wide margin and clear drawings, but from beginning to end there is not a useless word nor an errant paragraph. Enthusiasm may, of course, carry an author beyond the field worked by a slower or more conservative colleague; many good eye surgeons still obtain fine results by trial lenses, ophthalmometry, and the ophthalmoscope ;some oppose the methods as interpreted to be "objective," for, although it is evidently independent of the patient's response, it nevertheless is not yet capable of being automatically documented, as a true objective method should. This has nothing to do with the book itself, however, as the student should use it, for, as a text book of practical refraction, it is invaluable. Those who have used the earlier editions will be glad of the newer one; those who are beginning to study the "Shadow-test" cannot do better than to purchase Thorington's book. --Annals of Ophthalmology, Volume 10
