  • Publication number: 20070112456
    Abstract: These and other objectives are attained with a method and system for recording data monitored during the manufacture of molded ophthalmic lenses. This method comprises the steps of identifying a set of process parameters used in said manufacture, identifying an associated value range for each of the process parameters, and monitoring each of the process parameters during the manufacture of the lenses. If, during the manufacture of one of the ophthalmic lenses, one of the process parameters moves outside the associated value range, then that lens is rejected. However, if, during the manufacture of one of the ophthalmic lenses, all of the process parameters stay within their associated ranges, then that lens is identified as acceptable, and a device history record is made for that lens. This device history record includes a reference code for identifying the set of process parameters.
