A pair of eyeglasses includes rear view mirrors, each having a mirror surface substantially equal in area to that of a lens of the eyeglasses, that may be folded forwardly and outwardly to an open position for use, and that may later be folded rearwardly and inwardly to a closed postion for retention by the temple members of the eyeglasses when not in use. The rear view mirrors are somewhat concave in shape so that when in the closed position against the temple members, the eyeglasses present the appearance of conventional eyeglasses.
