Patent ID: 8260450

Claim:
An eyeglass lens processing apparatus for forming a hole on an eyeglass lens to attach a rimless frame to the lens, the eyeglass lens processing apparatus comprising: a lens chuck that holds the lens; a display; a designating unit configured to designate a position of a main hole to be formed on the lens; a drilling tool configured to form a provisional hole, having a diameter smaller than that of the main hole, through the lens; a unit configured to measure or input an inclined angle of a front refractive surface or a rear refractive surface of the lens at the designated hole position; an arithmetic unit configured to obtain a hole angle of the main hole with respect to a predetermined reference axis based on the input inclined angle or the measured inclined angle; a control unit configured to control a positional relationship between the held lens and the drilling tool; and a hole modifying unit configured to display a hole correcting screen on the display, wherein data of the position designated by the designating unit and the hole angle obtained by the arithmetic unit are displayed on the hole correcting screen, wherein data for modifying the hole angle is input through the hole correcting screen, and wherein the control unit performs a two step processing of forming the provisional hole through the lens and then forming the main hole through the lens, by controlling the positional relationship, the provisional hole is formed based on the obtained hole angle, and the main hole is formed based on the modified hole angle.
