Description: This book is full of useful information on ophthalmic lenses and their design, though it is perhaps a little too technical for the student or apprentice optician. However, it lacks basic dispensing techniques although the title indicates it covers this topic. Nonetheless, it is a very useful source for almost all aspects of lenses and their design.
Purpose: The purpose is to bring opticians up-to-date with the changes in lens types, materials, forms, and treatments. This edition also includes a CD-ROM on lens design to enhance the value of this book. The objectives of this book are indeed worthy, as the information is very detailed and current. The book meets the objectives and the average optician now has a very good source of lens information.
Audience: This book is written for all opticians, but the information is too intense for apprentice opticians (self taught) who are not enrolled in an accredited course of opticianry. The book is, however, an excellent source for master opticians, licensed opticians, instructors, and their students. The author states that students have commented on the ease of use of this book and perhaps that is true. I find the information would need much explaining to most students, so it could be a good book for students taking an opticianry course at an accredited institution. The author is very credible.
Features: This book covers all technical aspects of lenses and their design. It contains a wealth of geometric optics. It would be good for the student who is taking a written test for certification in opticianry whose requirements include geometric and physical optics. The CD-ROM makes the information in the book even more useful to the user. The book is sectioned off nicely and the use of color graphics is a nice enhancement. The main shortcoming is the lack of dispensing information. It does a good job of helping readers understand and design lenses, but not how to dispense them.
Assessment: I would recommned this book because of its intense detail about lenses and their design. Having this book as a reference in my dispensary will make it one of the best as it covers the theory and technical aspects of lens design. The books I have now are either outdated or not technical enough. The CD-ROM is a bonus and presents ophthalmic dispensing information in the most up-to-date format.
