  • Patent number: 9869882
    Abstract: The tensioning kit for spectacles comprises an elastic pad and a blocking post. The elastic pad and the blocking post are attached to the temple of the eyeglasses. The tensioning kit for spectacles is a device that inhibits the rotation of the temple of eyeglasses such that the temple is pressed against the head of the user in a manner that places a strain on the temple that deforms the temple. As the temple attempts to return to its relaxed shape, a force is exerted against the head of the user thus holding the eyeglasses in position. The tension applied is a function of the span of the arc that is inhibited by the tensioning kit for spectacles.
