ABSTRACT:
The invention is a method of printing a replica of the natural iris on a contact lens. The printing is done using a rubber printing member having up raised rubber radial segments having a radius of substantially the same as the contact lens. The printing ink is applied to the radial printing segments and the rubber stamp is applied to the lens. Pressure is then applied to the rubber stamp forcing the edges of the radial printing segments to move outward moving an amount of printing ink ahead of the advancing edge. The lens is rotated and the process is repeated forming a geometric pattern resembling the human iris.
