ABSTRACT OF THE DISCLOSURE A binocular includes a pair of telescopes each having a hollow body shell, a plurality of mirrors in the shell and arranged to provide a folded light path therethrough, eyepiece and objective barrels mounted on the shell and having, respectively, eyepiece and objective lenses therein and disposed at opposite ends of the Light path, such mirrors being ovally shaped and sized substantially to conform to the respective cross sections thereat of the light bundle transmitted by the objective lenses, the shell defining an internal arcuate mirror rim-receiving surface for each of the mirrors, and a portion of the rim only of each mirror being adhesively secured to the receiving surface therefor by an elastic adhesive; and hinge structure including a hinge post connecting the telescopes together for adjustment of the interpupillary spacing of the eyepiece barrels, such hinge post having a tapped hole therein. A spectacle-type mounting assembly for such binocular includes a spectacle frame embodying a bow and a pair of earpieces extending from opposite ends of the bow, first mounting structure centrally secured to the bow, second mounting structure including a threaded shank adapted for threadedly engaging the binocular hinge post in the hole therein, and structure for securing the first and second mounting means together adjustably in selected vertical positions relative to each other, for up and down adjustment of the position of the binocular hinge post relative to the position of the frame as worn by the user, in conformity with the adjustment of the interpupillary spacing of the eyepiece barrels.
