Abstract
A method for labeling an identification mark on a lens for inventory control. The identification mark is placed onto the facing inside surface of a mold by an ink jet printer and is remained there when the lens-forming liquid is cured. Once the lens is formed, but before the demolding, the identification mark is transferred from the mold to the lens. The identification mark contains information identifying the lens' properties such as the power of the lens and can be used for inventory control.
