ABSTRACT:
Glazing spectacles frames with correction of attending lens rim distortions by measuring the inner perimeter of the rims and edging the lenses to the measured perimetric size and proper pattern shape. Insertion of the edge lenses into the measured lens rims will cause the rims to conform to the edged lens profile and correct preexistent rim distortions.
