PROBLEM TO BE SOLVED: To provide a manufacturing method of a binocular loupe capable of attaching a loupe to a carrier lens at an angle according to a working posture of each individual worker.SOLUTION: The left and the right eyes are irradiated with infrared rays from infrared ray emitting diodes 36A and 36B in a state in which a subject takes a working posture and stares at a lower work operation site, and light reflected from the left and the right eyes is imaged by a pair of eye cameras 35A and 35B. The image data imaged is processed to calculate respective lines-of-sight direction of both eyes, and respective inner side and lower side installation angles to be installed on the surfaces of the left and the right carrier lens from the calculated lines-of-sight direction are determined. Openings are formed on the surfaces of the left and the right carrier lenses on the basis of the lower installation angle and the inner side installation angle, and the left and the right loupe are inserted and fixed to the openings, thereby preparing a binocular loupe. |
