    PREFATORY NOTE. The object of this little book, is to serve as a guide to the general practitioner in determining whether a given pa- tient does or does not require glasses, either to aid the vision or to relieve a symptom that may not be directly referred to the eye. It is by no means a complete manual of errors of re- fraction or failures in accommodation, but I believe that a careful study of these pages, will enable the practitioner to decide in a large proportion of cases, when the question comes up, whether or not glasses will probably be of service. I also hope, that the very busy man who is not inclined to seriously study the subject treated of in this little volume may get from the short time that he devotes to it, an accu- rate idea of how much has been accomplished in the last quarter of a century in adjusting glasses for the improve- ment of sight, and the mitigation and cure of distressing symptoms. New York, January, 1887.
