１の前後位置と上下位置が決定される。First, the eyepoint measuring tool 1 is mounted on the spectacle frame 3 by the mounting structure of the mounting portion 7 described above. FIG. 5 is a front view showing a state in which the eye point measuring tool 1 is attached to the eyeglass frame 3. The front-rear position and the vertical position of the eyepoint measuring instrument 1 in the spectacle frame 3 are determined based on the positioning relationship based on the contact of each part of the mounting portion 7 with the spectacle frame 3.

In this wearing state, the movable members 9 of the left-eye corresponding portion 5a and the right-eye corresponding portion 5b are separately moved left and right, and the corresponding long holes 41 of the movable members 9 are aligned with the pupils of the left and right eyes of the subject. Then, the numerical values of the horizontal scales 13a and 13b of the base member 5 indicated by the indicating line 43 of the long hole 41 are read. Thereby, the lateral position of each pupil of the left and right eyes (one eye PD),
That is, the distance from the center line O of the spectacle frame 3 to the center of each pupil of the left and right eyes is measured. In this case, since the lateral position of the pupil is measured by aligning the long hole 41 of the movable member 9 with the pupil of the subject, the accurate position can be measured for the measurer. In addition, the subject himself can also confirm the measurement state as to whether or not the alignment has been reliably performed by the subject's own consciousness because the visibility state becomes clear when the long hole 41 matches the pupil of the subject, As a result, measurement errors can be almost eliminated.

In the measurement of the position in the height direction, the positions of the pupils of the left and right eyes in the vertical direction are determined by a height scale 45 provided on the side of each long hole 41.
Done by Thus, the measurement of the pupil height position is performed simultaneously with the measurement of the pupil lateral position.

This is a point determined by an intermediate position between the left end and the right end of the shape of the lens to be mounted on each frame portion, and an intermediate position between the high end and the low end of the shape of the lens. In other words, the horizontal position of the geometric center of each frame portion is a distance from the center line O of the spectacle frame 3 to the geometric center point, and the height direction position is a reference point (arbitrarily determined. ) To the midpoint between the high and low ends of the lens shape. The distance from the center line O of the spectacle frame 3 to the geometric center point corresponds to the distance measured by the aforementioned horizontal scales 13a and 13b, and is between the high end and the low end of the lens shape from the reference point. Corresponds to the distance measured by the above-described height scale 45.

When the lateral position of the eye point is smaller than the lateral position of the geometric center, the contour shape of the lens is processed so that the optical center of the lens coincides with a position shifted inward by the difference between the two. Further, when the lateral position of the eye point is larger than the lateral position of the geometric center, the contour of the lens is processed so that the optical center of the lens coincides with the position shifted outward by the difference between the two.

The height position of the geometric center is compared with the measured height position of the eye point. When there is a deviation between the height position of the eye point and the height position of the geometric center, the contour shape of the lens is processed by shifting the difference by the difference to match the optical center of the lens. .

Therefore, if the eye points of the demo lenses 3a and 3b are made to coincide with the optical centers of the left and right lenses, the image of the contour shape of the lens to be processed can be easily grasped. Actually, the lens is automatically processed by the ball mill, and the operation control data for causing the ball mill to perform the desired processing operation uses the above-described eye point measurement data and geometric center measurement data. Is set.
