<P>PROBLEM TO BE SOLVED: To provide a positioning method of eye points for determining the position of the eye points in a spectacle lens more accurately than before by a simple method, and to provide a measuring method of the eye points. <P>SOLUTION: A subject is allowed to wear spectacles 31 for measurement. A seal is put on the lens 32, and the subject is allowed to closely observe LED light that is emitted toward the front from a through hole 11b in front of a front dark room 11. Then, while the subject is closely observing, the face section of the subject including a lens 32 is photographed. Then, with the seal being photographed to a photographed image as a reference, a pupil center that is photographed in an image, namely an eye point for a long distance is tentatively determined. Then, from the eye point for a long distance that is tentatively determined, the position of the actual eye point for the long distance is determined. <P>COPYRIGHT: (C)2004,JPO |
