Opis

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.
