ABSTRACT:
Binocular eyeglasses are provided for magnification of images, for example, when viewing television or when viewing distant images, such as a sporting event or the like. The binocular eyeglasses comprise a lightweight frame assembly including a lens carrying front frame with rearwardly extending bows permitting the eyeglasses to be worn in a normal manner. The front frame includes eyepiece lenses supported in stationary positions in front of the viewer's eyes and a respective pair of relatively wide-angle and relatively low-power objective lenses movable quickly and easily between close-range and long-range focus setting positions.
