Eyeglass lens processing apparatus calibrating method

Abstract

An eyeglass lens processing apparatus calibrating method is disclosed. The eyeglass lens processing apparatus includes an optical encoder. The eyeglass lens processing apparatus calibrating method includes steps of: (a) when a first object and a second object approach each other, using the optical encoder cooperated with an algorithm to detect whether the first object and the second object touch each other; (b) if a detection result of the step (a) is yes, ending detection immediately and feedbacking a trigger signal; and (c) calibrating a parameter of the eyeglass lens processing apparatus to a calibrated value according to the trigger signal.
