Patent number: 10254563Abstract: Method for defining one face of an ophthalmic lens, having a surface formed by superposing a Fresnel layer and a continuous surface referred to as the “carrier”. Also disclosed is an ophthalmic lens comprising such a face. The method allows a Fresnel layer to be defined that compensates for geometric effects induced by a variation in the curvature of the carrier on the light incident on the face of an ophthalmic lens. This method is particularly useful when the curvature of the face of the ophthalmic lens is adapted to facilitate fitting it into a spectacle frame.Type: GrantFiled: October 17, 2013Date of Patent: April 9, 2019Assignee: Essilor InternationalInventors: Bruno Amir, Pauline Colas, Mélanie Tessieres

Patent number: 10108028Abstract: The disclosed embodiments include a method for determining a geometric definition of a piece of personalized optical equipment adapted to its wearer, comprising at least one geometric definition of a personalized frame of this piece of personalized equipment. In one embodiment, the geometric definition of said personalized frame is determined depending on at least one geometric parameter of personalization of the frame and on a reference frame chosen by the wearer. Further, the value of said at least one geometric parameter of personalization of the frame being determined on the basis of the acquisition of data relating to at least one morphological quantity of the head of the wearer, in such a way that the personalized frame is adjusted to conform with a least one criterion of adjustment of personalization of the geometry of the frame with respect to the morphological quantity of the head of the wearer.Type: GrantFiled: December 22, 2014Date of Patent: October 23, 2018Assignee: Essilor InternationalInventors: Carlos Rego, Bruno Amir, Guillaume Broutin, Maxime Boiffier, Thierry Bonnin, Melanie Tessiere, Jerome Moine

Patent number: 9482884Abstract: The present disclosure provides systems and methods for determining an ophthalmic lens. In one implementation, three-dimensional coordinates of a center of rotation of the wearer's eye measured on the wearer in binocular vision are received. At least one direction of gaze measured in a natural posture and a determined position of the ophthalmic lens are received. Characteristics of the ophthalmic lens are calculated by using the coordinates measured for the center of rotation of the eye, the determined position of the lens, and the at least one direction of gaze measured in a natural posture. The characteristics of the ophthalmic lens are calculated by positioning a starting ophthalmic lens in the determined position and modifying the starting ophthalmic lens by wavefront analysis and/or optimizing using ray tracing dependent on the coordinates measured for the center of rotation of the eye and the determined position of the lens.Type: GrantFiled: April 19, 2010Date of Patent: November 1, 2016Assignee: ESSILOR INTERNATIONAL (COMPAGNIE GÉNÉRALE D'OPTIQUE)Inventors: Jean-Pierre Chauveau, Frederic Dubois, Cyril Guilloux, Melanie Tessieres, Helene De Rossi
