Publication number: 20160320302Abstract: An index value is calculated for rating an eyeglass with respect to protection against UV hazard. The index value is based on an integrated UV transmission value through the eyeglass and an integrated UV reflection value related to a back face of the eyeglass. Thus, the index value takes into account actual wearing conditions where UV eye exposure is due either to transmission through the eyeglass or reflection on the eyeglass back face. Respective index values obtained for a set of eyeglasses allow easy sorting of the eyeglasses with respect to UV protection efficiency.Type: ApplicationFiled: July 8, 2016Publication date: November 3, 2016Applicant: ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUE)Inventors: Karl CITEK, Gilles BAILLET, Francisco DE AYGUAVIVES, Gabriel KEITA

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
