| 20110166834 | Method for Optimizing the Settings of an Ophthalmic System - A method implemented by computer means, for optimizing the settings of an ophthalmic system comprising an ophthalmic lens arranged to be fitted in a spectacle frame according to a given wearer, the method comprising the steps of: providing to the computer means wearer, frame and lens data comprising a 3D representation of the, respectively wearer's face, frame and lens, generating positioning data based on the wearer, frame and lens data, said positioning data comprising the respective position of the wearer face with respect to the spectacle frame associated with the ophthalmic lens, and upon a modification request, modifying the settings of the ophthalmic lens to be manufactured and fitted in the spectacle frame, so as to modify the positioning data. | 07-07-2011 |
| 20100283963 | PROGRESSIVE LENS FOR OPHTHALMIC SPECTACLES, HAVING AN ADDITIONAL ZONE FOR INTERMEDIATE VISION - A progressive lens for ophthalmic spectacles has an additional zone for intermediate vision. This additional zone is located beneath a near-vision zone. It enables objects located at a distance of between 1.0 and 1.5 meters, in a direction inclined at about 35 degrees to a line of sight passing through a cross mark (CM) on the lens, to be seen clearly. To achieve this, the optical power progression between a far-vision point (FV) and a near-vision point (NV) of said lens has a power-increase threshold which is located approximately at the cross mark. | 11-11-2010 |

| 20080246914 | Ophthalmic Lens - The invention concerns an ophthalmic lens having a complex surface, with a substantially umbilic meridian and an average sphere progression ranging between 0.50 diopter and 0.75 diopter. The lens is prescribed for esophoric and non-presbyopic users. The lens is prescribed as a standard unifocal lens. Through the presence of the average sphere progression, the user is less adapted to near vision, thus compensating for his/her esophoria. | 10-09-2008 |
