ASYMMETRIC BLADDER COMPRESSION FOR ELIMINATION OF LAMINATION DEFECTS ON MULTIFOCAL LENSES
摘要
<p>A method and apparatus for elimination of lamination defects on progressive addition lenses. The lamination method uses a flexible bladder designed to apply pressure evenly across the lens surface. A spacer is positioned between a Hard Multi-Coat carrier and the flexible bladder. The spacer is located in a region of the carrier which is designated to deliver a coating to a section of the lens which is farthest from the carrier. The spacer asymmetrically increases the pressure applied to the carrier to eliminate lamination defects.</p>
