Abstract: A method for tracking multiple SKUs of contact lenses in a manufacturing line comprising the steps of: a) molding a plurality of contact lenses, b) providing a plurality of carriers each having a carrier indicator, c) inspecting each contact lens to determine information relating to its prescription, d) transferring each lens to a carrier, e) reading the carrier indicator of the carrier of step d) and f) storing in machine-accessible memory the information associated with the carrier indicator of the carrier of step (e) and the information relating to the lens for step (c).

Abstract: Method and apparatus for applying an identifying mark to a mold used for making an ophthalmic device whereby the mold may be identified at various points along a production line in a fast, reliable and automatic manner. The mark is applied to a non-optical surface of the mold and is read using a reading device and a light source positioned on either side of the mold whereby the light rays enhance the contrast between the identifying mark and the mold. In a preferred embodiment, the identifying mark is a 2D matrix which is formed on the non-optical mold tool used in the injection mold machine which makes the mold. The 2D matrix on the non-optical mold tool is then replicated on the non-optical surface of the mold.

Abstract: A method and apparatus for confirming the presence of a contact lens in its intended package employs an infrared detection system that is able to detect the presence or absence of a contact lens in the package.

Abstract: A method and apparatus for confirming the presence of contact lens packages in a secondary carton is disclosed, where a sensor that detects the presence or absence of metallic lidstock of the packages through the secondary carton.
