Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a visual axis vector detecting system applicable for a user of spectacles. SOLUTION: The visual axis vector detecting system is provided with an infrared ray source illuminating the eyes or the face, a camera photographing the eyes or the face, and a computer processing photographed image data of the camera and calculating a visual axis vector. The system is characterized in that the computer includes an image processing part detecting a real luminescent spot and a center of the pupil from the photographed image data, and a computing part calculating the visual axis vector; and the image processing part determines a luminescent spot satisfying predetermined requirements among luminescent spots having the pupil in the adjacency to the real luminescent spot, finds the center of the pupil, and executes the processing of finding the center of the cornea sphere.
