Highly readable and packed with instructional photos and drawings, this book also features a separate kit for practicing lens edging layout at home. Proficiency tests for self-assessment are included for each chapter and are an excellent review for examinations. Seven new chapters cover changes in the lens industry, lens insertion, rimless and semi-rimless frames, and lens tinting and engraving Contains a centration skills booklet for practicing lens edging layout Proficiency tests for self-assessment included with each chapter 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.
