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.
Claims13
A spectacle lens processing device comprising:
- a drilling tool that forms a hole in a lens;
- and
- a processor,
- wherein
- the processor
- acquires a position of the hole formed in the lens,
- acquires 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, and
- 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.
A spectacle lens processing device comprising:
- a drilling tool that forms a hole in a lens;
- lens holding shafts that sandwiches and holds the lens;
- and
- a processor,
- wherein
- the processor
- acquires a position of the hole formed in the lens, and
- determines, based on an angle of the lens held by the lens holding shafts, a relative angle between the drilling tool and the lens when the hole is formed in the lens in the position of the hole.
A non-transitory computer-readable medium storing computer-readable instructions that, when executed by a processor of a data generation device to generate processing control data used in a spectacle lens processing device including a drilling tool that forms a hole in a lens, cause the data generation device to perform processes comprising:
- acquiring a position of the hole formed in the lens;
- acquiring 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;
- and
- determining, 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.
A non-transitory computer-readable medium storing computer-readable instructions that, when executed by a processor of a data generation device to generate processing control data used in a spectacle lens processing device including:
- a drilling tool that forms a hole in a lens;
- and lens holding shafts that sandwiches and holds the lens, cause the data generation device to perform processes comprising:
- acquiring a position of the hole formed in the lens;
- and
- determining, based on an angle of the lens held by the lens holding shafts, a relative angle between the drilling tool and the lens when the hole is formed in the lens in the position of the hole.
