Inspired in part by Blodi's (1986) volume in the Hirschberg History of Ophthalmology series dealing with postage stamps depicting ophthalmologists, related scientists, medical researchers, and the eye in general, we have sought to create a work that will be of use not only to those with interest in the medical and optical fields, but also to numismatists. In general, we have followed Blodi's arrangement and topics, so that users of both volumes will be able to readily compare similar subjects across the two media. Like Blodi, we have been broad in our selection of topics, hoping to incorporate as much of the wide range of material relating to ophthalmology, its history, organizations and practitioners, including scientists whose impact on ophthalmology and optics was significant; optical firms and opticians; those who have lost total or partial sight and their rehabilitation; and, of course, the eye in its many symbolic and mythical uses. Casting the net wide in this way, we have captured a sizeable body of numismatic material. Generally, we have tried to be as inclusive and complete as possible, so that, for example, chapter I on ophthalmologists includes every object on this subject that we could locate having searched private and public collections, and a range of publications. This same level of inclusiveness holds true for chapters III, V, VIII, IX, X, XI and XII as well.
