Abstract: This invention discloses methods for generating one or both of an ophthalmic lens precursor with at least a portion of one surface free-formed from a Reactive Mixture. In some embodiments, an ophthalmic lens precursor is formed on a substrate with an arcuate optical quality surface via a source of actinic radiation controllable to cure a definable portion of a volume of Reactive Mixture.

Abstract: This invention provides for an ophthalmic lens with at least one portion of the lens including multiple voxels of polymerized crosslinkable material. In addition, the present invention provides for apparatus for generating an ophthalmic lens with one or more areas of different refractive indexes and a surface with one or both of a raised area and a depressed area.

Abstract: An apparatus in one example comprises a computer component that receives one or more images of one or more packaging materials from one or more imaging components. The computer component employs an analysis of the one or more images to make a determination of a package integrity of the one or more packaging materials.

Abstract: A method and system for verifying the presence of a lens in a transparent package. The method comprises the steps of moving the package into an inspection position, and conducting a light beam through the package and onto an image plane to form an image of the package on the image plane. The method further comprises the steps of generating a set of signals representing the image on the image plane, and analyzing those signals to determine whether a lens is present in the package. This analyzing step, in turn, includes the steps of searching the package image for images of discrete objects; and for each object image found in the package image, identifying values for a plurality of parameters, and analyzing those identified values according to a predetermined procedure to identify the object as a lens or as not a lens.

Abstract: On-line inspection of opaque, translucent and transparent elastomer sealed flexible and semi-rigid package seals is provided. In the case of highly reflective opaque seals of various elastomers and colors, low incident angle structured side lighting is used to locate and define the seal and highlight defects within the sealed area. For transparent i.e. highly light transmissive seals, not only is the low incident structured side lighting utilized to define the seal area, but back lighting of the package and seal is provided in order to then locate and classify defects within the seal boundaries. Multiple video images of portions of the area containing the seal and portions of the remaining lidstock are generated by CCD type cameras in response to one or more sensors which detect the presence and proper positioning of the package moving along a conveyor for image acquisition.
