Abstract:
An eye glass retention system that includes an eyeglass frame comprising a lens frame and first and second temple arms attached at a proximal end to the lens frame at opposing ends of the lens frame. At least one of the first and second temple arms has a temple arm cavity extending lengthwise of at least a portion of the at least one temple arm with a distal opening proximate a distal end of the at least one temple arm. A central post resides within the temple arm cavity extending axially of the temple arm cavity with a space surrounding the central post between the central post and an interior wall of the temple arm cavity. A retention band has a first and a second end. At least one of the first and second ends has an opening into a retention band cavity defined by a retention band sidewall extending lengthwise of at least a portion of the retention band. The retention band is configured so that the inner surface of the sidewall contracts inward when subject to axial tension and expands outward when subject to axial compression. The central post within the temple arm cavity is received in the retention band cavity through the opening of the retention band cavity and the retention band sidewall is received in the space surrounding the central post.
