Abstract
The invention relates to an eyeglass frame having a portion of the frame removably coupled to the body of the frame to permit the removal and replacement of the lenses in the frame. The frame includes a shoulder member that serves as a retainer plate and includes a leg portion and a recess located between the leg and a rear portion of the frame. A mechanism for disengaging the recess member can be accessed through the recess and pull of the leg portion to release the retaining member so that lenses can be removed and inserted.
