Lenses Spectacles Eyeglasses And Contacts

Two well-respected eyecare specialists, Dr. Walter J. Zinn and Dr. Herbert Solomon, offer important tips and sound medical advice on how to prevent, treat or correct eye-related problems for the visually-dependent 1990s. Computers at work and home, video games, cable-TV, CD-ROM and all the high-tech equipment available today may produce a lot of fun and communicate plenty of information, but they create one negative side effect: eye strain. This book authoritatively offers the best defense, with timely suggestions on how to maintain better eyesight. Written in easy-to-understand language, you will learn of the latest treatments, surgeries and eyewear available.

The Basic Bookshelf for Eyecare Professionals is a series that provides fundamental and advanced material with a clinical approach to clinicians and students. A special effort was made to include information needed for the certification exams in ophthalmic and optometric assisting, low vision, surgical assisting, opticianry, and contact lens examiners. This book was written by a licensed dispensing optician for the express purpose of teaching optometric and ophthalmic assistants everything they need to know about frames and lenses. Ophthalmic frames are discussed in great detail, including basic principles, materials, special adaptations, and selection. Fitting and dispensing instructions are also included to help you satisfy your patients and customers.

The only authoritative handbook on eyecare--invaluable and fully revised.

Both opticians and optometrists are trained to grind and polish lenses and then to take the surfaced lens and finish it by centering it optically and grinding the edges so that the lens fits in the shape of the chosen frame. Thoroughly revised and updated with seven new chapters to cover changes in the industry, this 2nd edition provides a step-by-step understanding of lens finishing for the optometrist or optician. Content has been completely updated, reorganized and expanded to include the most recent industry changes. Updated photos illustrate the most current types of lenses and enhance comprehension of lens finishing. Seven new chapters cover rimless and semi rimless frames; environmental and safety concerns; lens insertion and standard alignment; nylon cord and other groove mountings; lens tinting and engraving; progressive addition lenses; and lens impact and resistance testing. An appendix of specific British Standards allows the book to easily travel to the UK and other countries that fashion their dispensing programs after the UK model. The Lens Centration Skills Series provides exercises to practice lens finishing and reinforce material from the text.

Presents a history of vision aids from ancient times to the present and discusses the medical care offered by ophthalmologists, optometrists, and opticians, and what new development can be expected in the future.
