Patent number: 9164201Abstract: A lens (1) includes a plurality of optical surfaces (S1, S2) each of which is made up of an alternation of active zones (ZA1, ZA2) and separation zones (ZS1, ZS2). The active zones of one of the surfaces are situated beside the separation zones of the other surface. The shape of one at least of the optical surfaces is then adapted into the separation zones in order to augment the acute angles that are situated at the convergence of active zones and separation zones. The lens can thus be made with improved accuracy with respect to a target optical function.Type: GrantFiled: September 6, 2012Date of Patent: October 20, 2015Assignee: ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUEInventors: Bruno Fermigier, Eric Gacoin

Patent number: 8210677Abstract: A disk enabling modification of the power of an optical component consists of a Fresnel lens. The disk is initially formed with a general rounded shape which corresponds to the shape of the optical component. In this way, the disk does not lose its shape or does not lose it very much when it is applied against the component. It does not cause image distortion or optical aberration when an object is observed through the component provided with the disk. Such a disk is particularly adapted to obtain correction of ametropia or to a solar mask initially lacking optical power.Type: GrantFiled: May 29, 2007Date of Patent: July 3, 2012Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Bruno Fermigier, Francois Guilhaumon, Matthieu Koscher, Sylvie Maze

Patent number: 6533416Abstract: Toric contact or intraocular lenses having a correcting portion characterized by one or more novel constructions that each produce an optical path that improves angular misalignment tolerance. The lens may be constructed with a “smooth atoric” aspect where the optical path through the correcting portion of the lens corrects for both astigmatism and an axisymmetric aberration other than astigmatism, there being no sudden surface discontinuity between the regions that provide the different corrections (thus, “smooth”). In another embodiment, the lens may be constructed with so-called “sectors” circumferentially arranged around the optical axis such that an optical path through the correcting portion of the lens varies as a function of the angular separation from the reference meridian plane, and the correcting portion is divided into at least two sectors having different astigmatism correction axes.Type: GrantFiled: July 20, 2001Date of Patent: March 18, 2003Assignee: Ocular Sciences, Inc.Inventors: Bruno Fermigier, Richard Legras, Nicolas Chateau

Patent number: 6379008Abstract: A method of determining the shape of an ophthalmic contact lens for correcting optical aberrations of the eye beyond defocusing or astigmatism includes the steps of measuring the optical aberrations of the eye to be corrected, determining the shape of the rear face of the lens from the measured topography of the cornea in order to obtain a predetermined mechanical behavior of the lens when it is placed on the eye, measuring the optical aberrations of the eye to be corrected, and determining the shape of the front face of the lens from the measured optical aberrations of the eye to be corrected combined with data relating to the shape determined for the rear face of the lens in order to correct the aberrations. The system includes measurement units for measuring the topography and the aberrations of the eye and an electronic calculator unit.Type: GrantFiled: September 22, 2000Date of Patent: April 30, 2002Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Nicolas Chateau, Gildas Marin, Bruno Fermigier
