An apparatus for eliminating the differences in the curvatures of a facing lens blank and an abrasive pad mounted on a formable lap includes a drivable track portion, a compensation plate disposed on the drivable track portion, and a compensation member removably disposed on the compensation plate. The compensation member is removable from the compensation plate by a carriage supporting the lens blank and is disposable between the lens blank and the formable lap. The method for compensating for the differences in curvatures of the formable lap and lens blank includes inserting the compensation material onto the formable lap, softening the formable lap, placing the lens blank over the compensation material to cause the formable lap to conform to a shape of the lens blank, allowing the formable lap to cure, removing the lens blank, and removing the compensation material. |
