Patent number: 8814354Abstract: A process for designing an ophthalmic progressive eyeglass comprises providing an initial front surface and an initial back surface. Respective addition values of front and back surfaces of the eyeglass are varied based on said initial front and back surfaces using a surface derivation tool. These surface addition values are selected so that the eyeglass exhibits an eyeglass addition value which matches a wearer's prescription and a value for a design feature which matches a target value. Said target value may be used for customizing the ophthalmic progressive eyeglass. The process does not require point-to-point surface optimization.Type: GrantFiled: December 24, 2010Date of Patent: August 26, 2014Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Marie-Anne Berthezene, Bernard Bourdoncle, Laurent Calixte, Cyril Guilloux, Jérôme Moine, Soazic Mousset, Damien Paille

Patent number: 7806526Abstract: The invention relates to a progressive ophthalmic lens and to a method of producing one such lens. Variations in the optical power and the astigmatism of a progressive ophthalmic lens (10) result from (i) spherical and cylindrical variations in the anterior face (2) of the lens and (ii) variations in another physical unit of the lens. In this way, it is possible to customise the design of the progressive lens as a function of at least one behavioural characteristic of the lens wearer. Said customisation can be repeated by modulating the values of the physical unit between the different points of the lens. As a result, progressive lenses with different designs can be obtained from identical semi-finished lenses. The physical unit can comprise the sphere and the cylinder of the posterior face of the lens (3).Type: GrantFiled: December 19, 2005Date of Patent: October 5, 2010Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Bernard Bourdoncle, Bruno Decreton, Cyril Guilloux

Patent number: 7755762Abstract: A method of improving an initial color filter comprises a numerical generation of sinusoidal spectra. Two steps of selecting said spectra are then executed. The first selection is carried out according to a criterion of colorimetric similitude with respect to the initial filter. The second selection is carried out according to the capacity of dummy filters corresponding to each spectrum to restore hues in a natural manner. To do this, observations of samples of hues through each dummy filter are simulated numerically, using a color appearance model to take account of a visual perception of a human observer. In this way, an improved filter is determined, which has a color close to that of the initial filter and which affords a natural rendition of hues.Type: GrantFiled: August 15, 2007Date of Patent: July 13, 2010Assignees: Essilor International (Compagnie Generale d'Optique), Centre National de la Recherche Scientifique-CNRSInventors: Gilles Baillet, Bernard Bourdoncle, Margalith Harrar, Françoise Vienot

Patent number: 7659982Abstract: A quantitative evaluation of a color filter (10) in accordance with the capacity of said filter to restore hues comprises the use of a numerical color appearance model. Values of a perceptive attribute are calculated for hue samples (20), by simulating the observation of each of the samples through the filter (10) and without a filter. The values of the perceptive attribute correspond to the visual perception of the samples by an observer (40), and a deviation between the values with and without filter constitutes the result of the evaluation of the filter. Such a method makes it possible to quantitatively rank several color filters, and the ranking obtained corresponds to that which would be established by real observers evaluating the filters.Type: GrantFiled: August 15, 2007Date of Patent: February 9, 2010Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Gilles Baillet, Bernard Bourdoncle, Margalith Harrar, Françoise Vienot

Patent number: 7427134Abstract: A progressive multifocal ophthalmic lens has a complex surface having a prism reference point, a fitting cross, a progression meridian having a power addition greater than or equal to 1.5 diopters.

Patent number: 7210780Abstract: The subject of the invention is a method for determination by optimization of an ophthalmic lens for a wearer for whom a power addition has been prescribed. The method proposes using as a target for the optimization of the lens, under wearing conditions, a difference of the mean orientation of the axes of resulting astigmatism to the vertical of less than 2.5° in a first control zone delimited by an ellipse centred on the progression meridian at half height between the fitting cross and the near vision reference point, said ellipse having a major axis greater than 35° and a minor axis comprised between 3.8° and 4.5°. The invention allows improvement in the performances of the progressive multifocal lenses in intermediate vision.Type: GrantFiled: June 14, 2006Date of Patent: May 1, 2007Assignee: Essilor International (Compagnie Generale D'Optique)Inventors: Bernard Bourdoncle, Gildas Marin
