| 20100296053 | METHOD FOR PROVIDING A SPECTACLE OPHTHALMIC LENS BY CALCULATING OR SELECTING A DESIGN - A method for providing a spectacle ophthalmic lens to a wearer, the method comprising: measuring the higher order aberrations in at least an eye of the wearer; calculating a design of the spectacle ophthalmic lens or selecting a design in a spectacle ophthalmic lens design data base by adapting the management of residual astigmatism based on the measure of higher order aberrations in the eye of the wearer. | 11-25-2010 |
| 20100149492 | Method for Determining an Ophthalmic Lens - The invention relates to a method for the optimisation determination of an ophthalmic lens that comprises the steps of: measuring parameters representative of the eye-head behaviour of the wearer; determining a central area on the lens having a diameter (D | 06-17-2010 |
| 20100134789 | DEVICE AND A METHOD FOR MEASURING A CAMBER GEOMETRICAL CHARACTERISTIC OF AN OPHTHALMIC LENS - A device for measuring at least one camber geometrical characteristic of an ophthalmic lens provided on at least one of its faces with at least one position-identifying mark, the device including a support for the ophthalmic lens, and on opposite sides of the support, firstly lighting element for lighting the ophthalmic lens along at least two different lighting directions, and secondly acquisition and analysis element for acquiring and analyzing the light transmitted by the ophthalmic lens, the analysis element being adapted to identify shadows of the mark when lighted in the at least two lighting directions, and to deduce from their positions a measured value for the camber geometrical characteristic of the ophthalmic lens. | 06-03-2010 |
| 20100091241 | METHOD AND SYSTEM TO ASSESS OBJECTIVELY VISUAL CHARACTERISTICS - A method to assess objectively visual characteristics of one eye ( | 04-15-2010 |
| 20090125137 | Method of Manufacturing an Optical System - The invention relates to a method of calculating an optical system (OS), the optical system (OS) being identified by a function (OF), the optical system (OS) comprising a first part (F | 05-14-2009 |
| 20090093194 | METHOD AND A DEVICE FOR EDGING AN OPHTHALMIC LENS FOR MACHINING THE EDGE FACE OF THE LENS TO A DESIRED CURVE - A method and device for edging an ophthalmic lens, includes turning the lens about a first axis of rotation and working on the edge face of the lens with a beveling grindwheel or cutter having a beveling groove or chamfer and mounted to rotate about a second axis of rotation. While machining the edge face of the lens with the beveling grindwheel or cutter, the first and second axis of rotation are moved dynamically relative to each other as a function of the angle of rotation of the lens about the first axis of rotation, in such a manner that during machining of each portion of the edge face of the lens, the tangent to the curve of the working portion of the beveling groove or chamfer is substantially parallel to the tangent to the curve of the bevel desired on the portion of the edge face. | 04-09-2009 |
