Patent application numberDescriptionPublished
20080207092Method of Centering a Non-Edged Ophthalmic Lens in Which the Centering Point of the Lens is Offset Relative to Its Geometric Center - The invention relates to a method for centering an uncut single vision ophthalmic lens (08-28-2008
20090140036METHOD OF ACQUIRING OF AT LEAST A PORTION OF THE SHAPE OF A SECTION OF A SPECTACLE FRAME CIRCLE - The method includes acquiring at least one geometrical characteristic of the section, which includes: a step of reading from a register (06-04-2009
20090308542DEVICE FOR APPLYING A COATING ON A LENS, THE DEVICE INCLUDING MEANS FOR INFLATING A MEMBRANE - A device for applying a coating film (12-17-2009
20100006219METHOD OF APPLYING A COATING ON A FACE OF A LENS, AND APPARATUS FOR IMPLEMENTING SUCH A METHOD - Described is a method and a device for applying a coating film (01-14-2010
20100112908METHOD OF SHAPING AN OPHTHALMIC LENS - A method of shaping an ophthalmic lens includes machining the edge face of the lens by at least one rotary tool having an axis of rotation movable relative to the lens axis, both in rotation and radial and axial translation. These movements are controlled so that the edge face of the lens presents a profiled shape with an engagement ridge suitable for engaging in a bezel of eyeglasses and first and second margins. Given first and second longitudinal curves of the first and second margins, respectively, the edge face of the lens is machined in such a manner that, at each axial section of the lens, the traces in the axial section of the first and second longitudinal curves present first and second distances from the axis of the lens, with the difference (rs) therebetween being a function of the position of the plane of the axial section under consideration.05-06-2010
20100184356DEVICE FOR MACHINING AN OPHTHALMIC LENS - The shaper device for shaping an ophthalmic lens comprises a blocking support on a blocking axis, a shaper tool, an electronic or computer unit for controlling the position of said shaper tool, and a man/machine interface connected to said electronic or computer unit, and comprising a display screen (07-22-2010
20100309429VISUAL DEVICE INCLUDING AN OPHTHALMIC LENS HAVING A PARTIALLY CROPPED INSERTION RIB, AND METHOD FOR PREPARING SUCH LENS - Visual equipment includes an ophthalmic lens having an edge face provided with an engagement ridge. Also described is a method of preparing such equipment. The engagement ridge includes at least fifteen bearing sections alternating with as many free singular sections, the free singular sections being smaller in width and/or in height by at least 0.05 millimeters relative to the bearing sections (Sa).12-09-2010
20100309430METHOD OF PREPARING AN OPHTHALMIC LENS WITH SPECIAL MACHINING OF ITS ENGAGEMENT RIDGE - A method of preparing an ophthalmic lens for mounting in a surround of an eyeglass frame includes an acquisition step of acquiring a first longitudinal profile of the surround and an orientation parameter of the first longitudinal profile relative to a horizon line or a verticality line of the surround, and an edging step of edging the ophthalmic lens so as to form a generally profiled engagement ridge of desired section that extends along a second longitudinal profile (12-09-2010
