Pierre Gerligand

Pierre Gerligand, Jacksonville, FL US

Patent application numberDescriptionPublished
20090168015METHOD FOR PROVIDING DUAL SURFACE PROGRESSIVE ADDITION LENS SERIES - Designing spectacle lens blanks for a dual-surface progressive addition lens (PAL) comprising determining a prescription range from a first set of first designs to produce a second set of first designs satisfying the prescription range, determining a common surface using the second set of first designs, and using the common surface to produce a set of second designs satisfying the prescription range.07-02-2009
20100045931Short Channel Progressive Addition Lenses - Designing a progressive addition lens includes using scaled surface powers and/or cylinder powers of base curves to determine a set of power targets, and using these targets to determine a lens design.02-25-2010

20090135371PROCESS FOR THE MANUFACTURE OF SPECTACLE LENSES - The invention provides methods for eliminating sharp edges that typically result during the production of uncut lenses.05-28-2009

Pierre Gerligand, St. Johns, FL US

Patent application numberDescriptionPublished
20110149229CONTACT LENSES WITH STABILIZATION FEATURES - Stabilized contact lenses have unconventional stabilization zones such as with the bulk of their length lying beneath the horizontal axis of the lens, a differing rate of change of slope (from peak) in one direction relative to the other, and a different height profile above the horizontal axis than below the horizontal axis.06-23-2011
20110149230STABILIZATION OF CONTACT LENSES - Contact lens designs are provided with improved stabilization wherein the moments of momentum are balanced.06-23-2011
20110149231METHOD FOR STABILIZING CONTACT LENSES - A method for stabilizing contact lenses includes providing a lens design with a nominal set of stabilization zone parameters, applying a merit function to the lens design based on balancing moments of momentum, and creating a contact lens design with improved stabilization based on the application of the merit functions to the lens design with a nominal set of stabilization zone parameters.06-23-2011
20110149232STABILIZED CONTACT LENSES - Contact lenses with stabilization zones are designed using mathematical constructs such as Bezier curves and which are subjected to modeling on-eye performance.06-23-2011
20110149233METHOD FOR PRODUCING STABILIZED CONTACT LENSES - METHOD FOR PRODUCING STABILIZED CONTACT LENSES Contact lenses with stabilization zones are designed using mathematical constructs such as Bezier curves and which are subjected to modeling on-eye performance.06-23-2011
