Structure and method for face form retention in eyeglasses and eyeglass frames for substantially preventing creep from altering the face form. The method comprises providing an eyeglass frame front having a space in the bridge region for receiving a metallic strip, providing the metallic strip having a width approximately matching the width of the space in the eyeglass frame front and a thickness that is less than its width, and fastening the metallic strip in the space in the bridge region so that the width of the metallic strip rigidifies the eyeglass frame front to retain its face form.
