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.
