  • Eyeglass frame with a reversible arm
    Patent number: 6530660
    Abstract: The present invention is directed to eyeglasses provided with at least one reversible arm that can be manipulated to fold in towards the outer (front) face of the lens retaining portion of the frame, thereby covering it. The arm can be attached to the frames in a variety of ways. For instance, the attachment can be mechanical, or magnetism may be employed in fixing the arm to the frame. Several structural arrangements are described that permit reversal of the arm from a position behind the lens retaining portion of the frame to a position in front thereof. The arm can then be folded to cover the front and back sides of the lenses.
