Abstract
An eyeglass lens processing apparatus includes: a piercing unit that includes a piercing tool for piercing a hole in an eyeglass lens; a first input unit that inputs position data and depth data of a non-through hole to be formed in a refractive surface of the lens; a detecting unit that detects a position of a front end of the piercing tool; and a control unit that controls a process of forming the non-through hole based on the detected front-end position data, and the input position data and the input depth data.
