Each movable member 9 is provided with a pupil position determining section 39 as shown in FIG. The pupil position determination unit 39
For example, it comprises an elongated slot 41 formed in the longitudinal direction of the movable member 9 and an indicator line 43 marked on the center line position of the slot 41. The instruction line 43 of the pupil position determination unit 39 is provided such that its upper end is located on the horizontal scales 13a and 13b. With the above configuration, since the tip end portion of the instruction line 43 of the pupil position determining portion 39 of each movable member 9 is located on the corresponding horizontal scale (13a or 13b), when the left and right movable members 9 are independently moved. The lateral position of the long hole 41 can be obtained based on the positional relationship between the tip of the indicator line 43 and the corresponding lateral scale. Accordingly, the lateral position of the pupil from the center line O of the spectacle frame 3 (substantially the horizontal position when worn) is measured. The lateral position obtained by the above measurement for each pupil of the left and right eyes corresponds to the one eye PD.

Next, the subject is made to wear the spectacle frame 3 with the eyepoint measuring tool 1 attached to 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 to the left and right, and the long holes 41 of the corresponding movable member 9 are aligned with the pupils of the left and right eyes of the subject. , The numerical values of the lateral scales 13a and 13b of the base member 5 indicated by the instruction line 43 of the long hole 41 are read. As a result, the lateral position of each pupil of the left and right eyes (PD for one eye),
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 exact position can be measured by the measurer. Also, the subject himself / herself can confirm the measurement state as to whether or not the alignment is surely performed by the subject's own awareness because the visibility state becomes clear when the oblong hole 41 coincides with his / her pupil. This makes it possible to eliminate measurement errors.
