Abstract: To provide binocular loupes capable of ensuring an optimal focal distance for a user using a simple operation, focus adjustment units disposed in eyepiece units of a pair of left and right loupe bodies of binocular loupes are provided with focus adjustment lenses, and holding rings having magnetic bodies into which the focus adjustment lenses are fitted. The holding rings are mounted in contact with correction lenses constituting optical systems inside the loupe bodies, are drawn and held by magnet rings. By this means, it is possible to readily replace the focus adjustment lenses by mounting the lenses detachably from the loupe bodies, and it is possible to ensure an optimal focal distance.
