Zusammenfassung: | PROBLEM TO BE SOLVED: To provide: an eye point measuring instrument system that eliminates the need for a complicated inexpensive dedicated device, imposes no physical burden on a subject, and can easily and accurately carry out measurement; an eye point measuring system; and a dummy lens used for the system. SOLUTION: The eye point measuring system includes: a spectacle frame 1 into which dummy lenses 11 are fitted, to which scales for eye point measurement are added in the lateral and horizontal directions around each center part where each pupil is positioned when being put on the subject; an electronic motion picture camera 2 for photographing a face part including at least a spectacle part of the subject wearing the spectacle frame 1; a computer 3 for processing electronic data photographed by the electronic motion picture camera 2; and a display device for displaying an image photographed by the electronic motion picture camera 2, or a printer 4.
