Claim Text:
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 (X (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 r (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 r
