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\ \ \ \ 4 Stars! from Doody\ \
