Industry Reviews

REVIEW OF CURRENT EDITION: "Most optical books presume the reader has some basic knowledge to build upon. This book, however, makes no assumptions and guides the reader through the steps necessary to become proficient with the foundations of everyday optics. The author did a very commendable job in achieving these important and necessary objectives. Learning optics can be intimidating for many but this book simplifies the important concepts in a succinct and easy to follow format. Every office that hires opticians or optical assistants should have a copy of this book." -Doody Enterprises "This book, accurately titled, is a detailed compendium of information required to understand lens finishing in an ophthalmic laboratory. The book is comprehensively written from the viewpoint of physically performing the activities and processes in a finishing laboratory. The most impressive aspect of this book is the thoroughness and extreme attention to detail. It is difficult to imagine a specialty situation or nuance that is not addressed in this book. Each chapter is enhanced with a liberal number of figures and photographs that are very useful.? - Optometry and Vision Science - VOL. 81
