To provide a method for processing a spectacle lens by which even a beginner simply processes an unprocessed spectacle lens into a ball-type shape by using measured data after easily measuring the peripheral edge shape of a lens for demonstration mounted to a rimless frame and also can simply drill a metal fitting mounting hole to the machined spectacle lens.

The method for processing a spectacle lens is constituted as follows. The peripheral edge shape of the lens for demonstration (the ball type 112) of the rimless frame is measured. A block center (the center of a lens suction jig 415, a processing center) is coincided with the measurement center O. The spectacle lens is processed at the center aligned with the measurement center O.
