1. A spectacle lens processing device comprising:
a drilling tool that forms a hole in a lens; and
a processor that is configured to:
acquire a position of the hole to be formed in the lens,
acquire a pantoscopic angle, the pantoscopic angle being an angle in a vertical plane between a visual axis of a user and an optical axis of the lens when the user wears spectacles in which the lens after processing is mounted and faces forward,
determine, based on the acquired pantoscopic angle, a relative angle between the drilling tool and the lens when the hole is formed in the lens in the position of the hole,
determine the relative angle based on one of a shape of the lens to be processed and a shape of a demonstration lens mounted in a rimless frame, on the acquired position of the hole, and on the acquired pantoscopic angle,
determine a provisional relative angle between the drilling tool and the lens based on one of the shape of the lens to be processed and the shape of the demonstration lens mounted in the rimless frame, and on the acquired position of the hole, and
determine the relative angle with which the hole is to be actually formed, by correcting the provisional relative angle based on the acquired pantoscopic angle.
