ABSTRACT:
A molded plastic resin contact lens marking fixture is provided having a cup-like base with an upstanding internal pedestal having an upper surface which is a segment of a sphere for receiving a contact lens. The axis of the segment is tipped from the vertical so that a peripheral portion of the lens is in uppermost position. A lid is received over the base and includes a masking area which is resiliently urged toward the uppermost portion of the pedestal. Perforations are provided in the masking area, and a dye well is provided above the masking area so that dye in the well will be transmitted through the perforations to mark a contact lens near the periphery thereof.
