Patent ID: 7427133

Claim:
An earpiece-less eyeglass apparatus, comprising: a lenticular frame for holding at least one eyeglass lens; first and second attachment mechanisms on each side of the lenticular frame for removably attaching a retainer strap directly to the frame; a retainer strap for retaining the lenticular frame on a user's face by placing the strap behind the user's head, said retainer strap having an end-piece at each end of the strap, said end-piece being compatible with the first and second attachment mechanisms to attach the strap to the frame and to remove the strap from the frame; and an adjustment mechanism for adjusting the retainer strap to provide greater or lesser tension on the frame, said adjustment mechanism including a slidable clasp for isolating a portion of the retainer strap thereby providing a retainer strap with a shorter effective length, wherein the slidable clasp has a mass sufficient to provide a counter-weight to the lenticular frame.
