Excerpt from Spectacles and Eyeglasses: Their Forms Mounting and Proper Adjustment
New ideas in the construction of spectacles, and especially in the construction of eyeglasses, continue to appear. In the present edition a description of the latest forms and methods of eyeglass fitting has been inserted. In bifocal lenses, also, there are new inventions to be described.
The art of spectacle fitting has greatly improved, and is now better understood than when the first edition of this book was published. Remembering his own novitiate, the author's aim is still to give practical help to the novice in learning the principles which underlie the art and in choosing that form of apparatus which best serves his purpose.
To the manufacturing opticians of his city, and particularly to Mr. A. Reed McIntire, the author wishes to express his obligation for freely imparted information as to processes of manufacture.
