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.
