20080212023 | Pixellized Optical Component with Apodized Walls, Method for Making Same and Use thereof in Making a Transparent Optical Element - The invention concerns a transparent optical component ( | 09-04-2008 |
20080231800 | Glasses Lens Comprising a Carrying Edge - A spectacle lens with an object-sided front face and an eye-sided rear face, wherein at last the rear face comprises a viewing region that contributes to the optical effect of the spectacle lens and a carrier rim region that at least partially surrounds the viewing region and that does not significantly contribute to the optical effect of the spectacle lens. The rear face of the spectacle lens in the carrier rim zone is constructed substantially from a cosmetic viewpoint without consideration of the optical image-forming properties. A method for producing this spectacle lens is also provided. | 09-25-2008 |
20080246915 | Inclined-edge sports lens - An optical lens has an inner lens surface and an outer lens surface separated by a lens thickness adjacent to an edge portion of the lens. The edge portion has at least a partially exposed edge surface extending substantially linearly from the inner lens surface toward the outer lens surface coextensively with at least a major portion of the lens thickness at a location adjacent to the edge portion, and at a predetermined inclination with respect to a portion of the lens surface at such location. | 10-09-2008 |
20090201463 | INSERTABLE CUT BLADE-STYLE EYEGLASS LENSES - A non-uniform thickness lens has a portion of a peripheral edge trimmed for secure engagement within a groove of blade style frame. Frame parameters are determined, such as by tracing the frame. The frame parameters include the plan layout as well as the contour and width of the engagement groove in the frame. The lens is edged to match the plan shape of the frame. The edged lens is then milled to reduce the thickness of the edge of each lens to a determined thickness along the contour corresponding to the non visual portion of the edge of the lens that will be engaged within the frame. The milled lens will fit securely in place in a blade style frame and without impairing the wearer's vision. | 08-13-2009 |
20100309429 | VISUAL 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 |
20110037945 | Beveling Wheel, Method for Forming a Beveled Lens for Use with Eyeglasses and a Beveled Lens - The present invention relates to a beveling wheel and method for forming a beveled lens with the beveling wheel for use with eyeglasses. One embodiment includes a prescription lens for use on an eyeglass frame having a receiving channel. The receiving channel includes a channel bottom and opposed interior wall surfaces having a first angle therebetween. The prescription plastic lens includes a prescription lens body generally defined by a peripheral edge having a bevel extending away from the edge to a vertex. The bevel has a distal portion with a second angle. The bevel is receivable within the receiving channel. At least a portion of the vertex of the bevel has an interference fit with the receiving channel bottom when held within the eyeglass frame. The first angle is greater than the second angle. | 02-17-2011 |
