    Inventors: Stephen Kendig, Cornelius Niculas, Jason Molinari, Nelson Baity
  • Contact lens design for large amplitude translation
    Publication number: 20060170861
    Abstract: The present invention is directed to a contact lens design where the optics position relative to the pupil is controlled by the lens relationship to the lower lid.

    Inventors: Joseph Lindacher, Corneliu Niculas
  • Using higher order mathematical functions to create asymmetric molding back pieces
    Publication number: 20060055071
    Abstract: This invention is related to creation of a mold for an ophthalmic lens using higher order mathematical functions, such as non-uniform rational b splines (NURBs), to create surfaces that do not contact fluid optical material, such as molding back pieces. In particular, the present invention optimizes the flow of mold material. Additionally, use of the present invention creates substantially uniform thickness of the mold, minimizing optical distortions.
