Abstract
A system for tinting contact lenses includes a transfer-pad printer adapted to pick up a pattern from an inked printing block and transfer the pattern to a soaked contact lens. A plurality of lens mounts, each adapted to fixedly hold a soaked lens in a defined position on a convexly curved top surface of the lens mount, are provided with reference means on their respective top surfaces to facilitate accurate placing of a soaked lens in the defined position on each lens mount prior to the pattern transfer from the transfer pad to the lens. The radius of curvature of the convexly curved top surface of each lens mount is slightly smaller than the radius of curvature of the base curve of a soaked lens placed on the lens mount to facilitate shrinking-on of the back surface of the soaked lens onto the top surface of the lens mount.
