Provided is a method for manufacturing a binocular loupe, the method including radiating strobe light from a below-located operational manipulating position in a state that the operator wearing the frame on which the carrier lenses are mounted stares the operational manipulating position in a working posture to use the binocular loupe, photographing reflection light of the strobe light reflected from pupils of the operator with a camera 11, specifying pupil positions based on the image data, and determining downward wearing angles r1, r2 of the loupe units which are to be attached to the right and left carrier lenses based on distance A from the operational manipulating position P to the carrier lenses and a horizontal distance B from the operational manipulating position P to a vertical line passing through the carrier lens. |

1. A method for manufacturing a binocular loupe in which loupe units are attached to carrier lenses mounted on a frame selected in accordance with an operator, comprising steps of:
(a) radiating strobe light from a below-located operational manipulating position in a state that the operator wearing the frame on which the carrier lenses are mounted stares the operational manipulating position in a working posture to use the binocular loupe; (b) photographing reflection light of the strobe light reflected from pupils of the operator with a first imaging device which is arranged at the operational manipulating position; (c) obtaining side posture image data of the operator in the working posture with a second imaging device which is arranged at either or both of the right and left sides of the operator at a position or positions being apart therefrom by a predetermined distance; (d) electrically specifying a right pupil position (X1, Y1) and a left pupil position (X2, Y2) of the operator from a center point of the frame based on front image data obtained by the first imaging device; (e) measuring, from the side posture image data, a distance A from the operational manipulating position to the carrier lenses and a horizontal distance B from the operational manipulating position to a vertical line passing through the carrier lens in a direction perpendicular thereto, and determining downward wearing angles r1, r2 of the loupe units which are to be attached to the right and left carrier lenses based on the measured distance A and distance B; (f) determining inward wearing angles p, q of the loupe units which are to be attached to the right and left carrier lenses based on linear distance C, D from the right pupil position and the left pupil position of the operator to the operational manipulating position and a distance G from the center point of the frame to the operational manipulating position; and (g) forming opening portions at the right and left carrier lenses based on the right pupil position, the left pupil position, the downward wearing angles r1, r2, and the inward wearing angles p, q, and inserting and fixing the right and left loupe units to the opening portions. |
