Publication number: 20230384617Abstract: Disclosed is an optical lens including at least one continuous scattering area having a characteristic dimension d greater than or equal to 2 mm. Any sub-area of characteristic dimension dsub included in the at least one continuous scattering area, with dsub greater than or equal to 0.05 mm, verifies: |% Iscat_area?% Iscat_subarea|<0.2*% Iscat_area, where % Iscat_area is the average intensity ratio of light scattered by the continuous scattering area, and % Iscat_subarea is the average intensity ratio of light scattered by the sub-area.Type: ApplicationFiled: October 8, 2021Publication date: November 30, 2023Inventors: Montserrat BURGOS, Eric GACOIN, Aref JALLOULI, Philippe VANEECKHOUTTE, Hao-Wen CHIU, Matthieu GUILLOT

Patent number: 11644689Abstract: An ophthalmic tinted lens has a visual transmission value TV for quantifying a first light intensity ratio which relates to light effective for human vision and transmitted through the lens in daylight condition, and also has a value of a chronobiological factor FC for quantifying a second light amount ratio which relates to light effective for a non-visual physiological effect and also transmitted through the lens in daylight condition. The TV-value and the FC-value expressed as percentage values meet the following condition: FC>1.1×TV+13.0 with 3%?TV?43%, or FC>0.7×TV+32 with 43%<TV?92%, for the ophthalmic tinted lens to combine solar protection and maintenance of circadian rhythms and better pupil constriction which are based on the non-visual physiological effect.Type: GrantFiled: February 11, 2019Date of Patent: May 9, 2023Assignee: Essilor InternationalInventors: Coralie Barrau, Montserrat Burgos, Natalia Schianchi

Patent number: 11137625Abstract: A computed factor allows quantifying the efficiency of a light filter to stimulate a non-visual physiological effect which is responsive to light entering into a subject's eye. The efficiency factor is based on a spectral light transmittance of the filter over the wavelength visible range, on a spectral sensitivity profile of the non-visual physiological effect, and on a spectral distribution of the light which enters into the subject's eye without using the filter. Such efficiency factor is useful in particular for an ophthalmic element designed for stimulating a non-visual physiological effect which is based on melanopsin light-absorption.Type: GrantFiled: December 21, 2016Date of Patent: October 5, 2021Assignee: Essilor InternationalInventors: Coralie Barrau, Montserrat Burgos

Patent number: 9475166Abstract: A method for cutting-out a multi-layer ophthalmic lens (100) following a desired contour (C3), includes: a step of pre-blanking the ophthalmic lens (100) using a preliminary tool (210; 223), according to a preliminary contour (C1, C1?); a step of blanking the ophthalmic lens (100) using a blanking wheel (210), following a blanking contour (C2, C3); and a step of finishing the ophthalmic lens (100) using a finishing tool (212). According to the invention, the preliminary contour (C1, C1?) is larger than the desired contour (C3), and the blanking wheel (210) used has a granulometry of between 0.1 and 0.5 mm and is controlled in relation to the ophthalmic lens (100) so as to apply a radial force of between 0.1 and 5 N to the ophthalmic lens (100) during the blanking step.Type: GrantFiled: May 3, 2013Date of Patent: October 25, 2016Assignee: ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUE)Inventors: Muriel Godeau, Aude Lapprand, Cedric Lemaire, Christian Massart, Gilles Massey, Sebastien Pinault, Catherine Roussel, Montserrat Burgos

Publication number: 20160216425Abstract: A functionalized layered structure (2, 3, 20, 30) includes: a first element that is a first single-layer or multi-layer functional film (2A, 4); at least one second element selected among a second functional film (2B) and a basic optical element (200, 300); at least one first pressure-sensitive adhesive layer (5A, 5B, 5) placed in contact with at least one surface of the first element and at least one surface of the second element. The surfaces of the first and second element, which are intended for being placed in contact with the adhesive layer, are subjected to a surface treatment prior to being placed in contact, such that the decrease between the peel force when dry and the peel force when wet is no higher than at least 35%, inclusive.Type: ApplicationFiled: July 1, 2014Publication date: July 28, 2016Inventors: Jeanne MARCHAL, Montserrat BURGOS

Publication number: 20150331259Abstract: A laminated optical lens having an edging-optimized laminar configuration and method for manufacturing same. The laminated optical lens includes an optical base lens and a film layered structure including an external film furthest from said lens. An adhesive layered structure is placed between the film layered structure and the optical base lens so as to permanently retain the film layered structure on the surface of the optical base lens. The laminated lens is manufactured by laminating a film layered structure having an external film to an optical base element with an adhesive layered structure. The external film has a thickness of at least 100 ???, and preferably a thickness in the range of 150 microns to 300 microns inclusive.Type: ApplicationFiled: December 28, 2012Publication date: November 19, 2015Applicant: ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUEInventors: Peiqi Jiang, Steven Weber, Marvin Pounders, Jeanne Marchal, Montserrat Burgos
