  • Patent number: 4733958
    Abstract: A visual field image reflector attached to standard eyeglasses to extend vision into an impaired lateral visual field characteristic of a patient suffering from homonymous hemianopsia. The reflector is attached to the eyeglass frame adjacent the patient's nose, forward the lens for an eye having an impaired lateral field and displaced from the line of central fixation of gaze. The reflector includes a light-transmitting substrate and two differently tinted coatings. The first coating, near the patient's eye, is a partially-reflective and partially light-transmitting yellow tinted layer. The second coating, away from the patient's eye, is a light-transmitting, blue-violet layer. The reflected image of the lateral field is thus observed in yellow by the patient, and the portion of the central field image transmitted through the reflector is seen in blue-green.
