It is an indisputable fact that the efficiency of the American troops during the late war was greater than that of any other army. One factor which contributed largely to their success is apt to be overlooked by the casual observer, but excited comment wherever our troops were thickest in the fray: Our men were properly glassed.
You, for whom this monograph is written, well know how thoroughly and systematically your eyes were examined. Perhaps you do not know that the actual testing of your eyes and the adoption of proper glasses whenever necessary to bring vision up to normal was done in a number of camps by optometrists.
What an important part glasses played in the success of our Army and Navy is a chapter yet to be written.
Now that the conflict is over it is fitting to call attention to the opportunity of entering a profession which has contributed so much to the winning of the war. And as optometry is a comparatively strange word to those not personally concerned with the profession, an explanation of its meaning had best preface this monograph.
