  • Publication number: 20190118498
    Abstract: A spectacle lens processing device includes a drilling tool and a processor. The processor acquires a position of a hole formed in a lens and a pantoscopic angle. The pantoscopic angle is 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. The processor determines, 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.
