20120002162 | METHOD FOR CUTTING A PATCH TO BE APPLIED ONTO A CURVED SUBSTRATE - A method cuts a patch to be applied onto a curved substrate and includes the preliminary calculation of curvilinear lengths on the substrate between a reference point and a peripheral edge of said substrate. The calculated lengths are applied to a planar film for making the patch, and then the patch is cut by connecting the ends of the applied lengths. The patch then precisely coincides with the edge of the substrate. Such a method is particularly useful for applying a functional film onto a spectacle lens, as a trimming of the lens after the film is assembled with the lens would degrade said film. | 01-05-2012 |

20120057123 | METHOD FOR PRODUCING COST-OPTIMIZED SPECTACLE LENSES WITH ESPECIALLY ADVANTAGEOUS PROPERTIES FOR THE USER - The invention relates to a method for the production of spectacle lenses from raw lenses prefabricated in a non-cutting manner. The raw lenses have a front side that is not to be reworked and an opposing back side to be reworked with a CNC machine, which sides have at least one optical focal point in common. In order to rework the back side a prescription surface is calculated on the basis of a prescription describing a visual error and of the geometry of the front side. This surface forms a prescription lens in common with the front side, the focal points of which lens correct the visual error. The front side is shaped in such a manner that it is a convex and rotationally symmetrical first freeform surface. This freeform surface is composed in a rotationally symmetrical manner about a middle axis by at least two spherical sections with different radii, whereby the spherical sections border each other tangentially. Furthermore, the spectacle lens has an optical center through which an eyeglass wearer looks when looking straight ahead (zero view direction). The spectacle lens is manufactured in such a manner by an adaptation of the raw lens to an eyeglasses frame that the middle axis of the raw lens lies outside of the optical center of the spectacle lens. | 03-08-2012 |
