Special eyeglasses for use in microsurgery

Special eyeglasses, designed to be used with the operating microscope, are described. These eyeglasses, which fit inside the eyecups of the oculars of the microscope, give the wearer a better view through the microscope than do conventional glasses and at the same time enable him to shift his vision to the surgical field or the instrument table without a sacrifice in clarity. Because they permit the wearer to maintain the eyecups of the oculars in the “up” position, the eyeglasses also prevent interference from outside illumination.
