An optical device comprising a spectacle frame having a pair of optical lenses. The optical device further includes a lens assembly pivotally attached to the spectacle frame which is pivotable between an operative position and a non-operative position. The optical device also includes an detent mechanism for repeatedly positioning the lens assembly into the operative position from the non-operative position. The lens assembly includes a support bracket for holding a pair of telescopes. The support bracket is contoured to the shape of the spectacle frame so that the bracket is substantially out of a user's forward line of sight when the lens assembly is in the operative position.
