A method for controlling a production line for the manufacture and/or packaging of contact lenses which production line simultaneous by processes at least two lots, the method comprising dividing at least a portion of the production line into a series of cells through which the contact lens pass sequentially, and providing a control system comprising at least three shifts registers each containing information about each of said cells, including: (a) a location shift register which indicates whether a cell should be empty or occupied, (b) a lot data shift register which is a non-binary shift register and contains manufacturing and/or prescription data about the contact lens which should be in the cell and (c) a condition shift register which provides an indication of the condition of the product in the cell, and simultaneously indexing all of said shift registers as a lens passes down the production line from one cell to the next cell.

Production line control using shift registers for contact lens manufacture

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).

Contact lens manufacture

A method and apparatus for detecting under- or over-filling of lenses in packages where ultraviolet radiation is directed to the package.

Method and apparatus for detecting lenses in package

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.

Method and apparatus for detecting contact lenses

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.
