Method for making an eyeglass lens coate and intermediate assembly for the production of a coated eyeglass lens for said method

Abstract

Method for making an eyeglass lens coated by means of physical vapor deposition PVD, such method comprising a step of arranging a lens blank, provided with a first centering reference, a step of arranging a support body, provided with a first abutment seat for the lens blank and with at least one first shaped and through opening oriented with respect to a second centering reference thereof, and astep of arranging a centering template provided with a second abutment seat for the support body and with a second through opening. The present method then comprises an assembly step, in which the lens blank is housed in the first abutment seat, orienting the first centering reference with respect to the second centering reference, and in which the support body is housed in the second abutment seat with the first and the second through opening aligned. Subsequently, the present method comprises a step of coating the lens blank by means of physical vapor deposition PVD, in which at least one coating layer is deposited on the lens blank, such layer provided with an exposed profile coinciding with the first shaped and through opening, and finally comprises a cutting step in which the lens blank is cut along a cutting profile shaped in eyeglass lens form and oriented with respect to the first centering reference.

Description

technical field [0001] The invention relates to a method for manufacturing spectacle coating lenses through PVD physical vapor deposition and a support body for lens blanks. [0002] The method and the support involved are intended for use in the eyewear industry in the manufacture of spectacle lenses in question which are optimally coated with a color coating, in particular with a mirror coating. [0003] Furthermore, it is advantageous that the support in question is intended for use in the method in question for producing a spectacle coating and that the coating is shaped and oriented relative to the edge of the spectacle coating. [0004] Therefore, the present invention is suitable for the field of eyeglass industry and eyeglass production. Background technique [0005] To make glasses more appealing to the outside world, glasses with "mirror" lenses, or coated lenses, have been introduced over the years that act like a mirror to reflect an image of the surrounding env...

Problems solved by technology

[0022] The disadvantage of the above-mentioned specular method is that the coloration obtained by the coating is not uniformly distributed on the lens blank, having a fine distribution whose intensity and coloration vary from the periphery of the lens blank to its interior

[0037] In this respect none of the graduated edges on lens blanks achieved by methods of the known type described above has so far been able to impart a significant aesthetic effect to the lens

Moreover, and more generally, it is not yet easy to take into account the position of the coating stage relative to the lens blank of the support, so as to obtain a shape designed in the orientation of the lens blank and then cut according to the designed shape, and to take into account the shape of the lens to be produced
