20090068932 | METHOD AND DEVICE FOR TRIMMING A LENS BY CUTTING SAID LENS - The present invention relates to a device and to a method for shaping an optical lens. According to the invention, a selection is provided between either a first tool ( | 03-12-2009 |
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 |
20100002187 | PAIR OF OPHTHALMIC EYEGLASSES AND A METHOD OF FORMING AN ENGAGEMENT PERIPHERAL RIDGE ON THE EDGE FACE OF A LENS - A pair of eyeglasses includes: a frame provided with at least one rim presenting an internal bezel; and a lens mounted in the frame, the lens presenting a front face, a rear face, and on its edge face, an engagement peripheral ridge presenting a rear flank, situated beside the rear face of the lens and a front flank situated beside the front face of the lens, the front and rear flanks being engaged in the internal bezel. The front flank of the engagement peripheral ridge presents continuity of at least first order with the remainder of the front face. The edge face of the lens presents a rear shoulder or foot, and in that the radial height of the engagement peripheral ridge considered between the peak of the peripheral ridge and the foot varies along the periphery of the lens. | 01-07-2010 |
20100195045 | METHOD OF MEASURING AT LEAST ONE GEOMETRICO-PHYSIOGNOMIC PARAMETER FOR POSITIONING A VISION CORRECTING EYEGLASS FRAME ON THE FACE OF A WEARER - A method of capturing a substantially front-view image of the face of a wearer wearing at least one frame ( | 08-05-2010 |
20100220286 | AUTOMATIC PUPILLOMETER WITH VISUAL VERIFICATION - The invention relates to an automatic pupillometer comprising a light source suitable for generating a corneal reflection on at least one of the eyes of an individual facing first and second windows, a collimator lens serving at least to position the light source to correspond to far vision of the individual, a detection receiver for automatically locating said reflection, and a calculator for calculating the pupillary distance of said individual. According to the invention, the pupillometer also comprises a third window where the eye of an observer responsible for the measurement is designed to be placed in the vicinity of the focus of said lens so as to view and verify measurement conditions. | 09-02-2010 |
20130190919 | TEMPLATE FOR CALIBRATING A MACHINE USED TO MACHINE AN OPHTHALMIC LENS, DEVICE AND METHOD USING SUCH A TEMPLATE - A calibration template for calibrating a machining device that has blocking elements for blocking an ophthalmic lens, and machining elements for machining the ophthalmic lens, the template including a fastener portion suitable for being fastened to the blocking elements and a calibration portion arranged around the fastener portion. The calibration portion is made out of a material that is suitable for being machined by the machining elements, and presents firstly a plurality of shape patterns, and secondly a plurality of visual identifiers each visually associated with one of the shape patterns. | 07-25-2013 |
