<p>Provided is a method for measuring pupil position whereby, in each lens area of a bifocal lens, a pupil position on the lens surface can be exactly and easily measured. The method for measuring pupil position comprises: irradiating a subject (2) wearing an eyeglass frame (1) with stroboscopic light from a far sight measurement position; capturing an image of reflected light of the stroboscopic light from a pupil of the subject (2) with a camera (11) at the far sight measurement position; electronically specifying, on the basis of the image data obtained by image capturing, a right pupil position (X1, Y1) and left pupil position (X2, Y2) of the subject (2) from the center point (O) of the eyeglass frame (1); irradiating the subject (2) wearing the eyeglass frame (1) with stroboscopic light from a near sight measurement position; capturing an image of reflected light of the stroboscopic light from a pupil of the subject (2) with the camera (11) at the near sight measurement position; and electronically specifying, on the basis of the image data obtained by image capturing, a right pupil position (X3, Y3) and left pupil position (X4, Y4) of the subject (2) from the center point (O) of the eyeglass frame (1).</p> |
