Embodiment Construction

[0044] FIG. 1 shows the application of a volume of liquid material in relation to the edge thickness Δx, for example a droplet volume ΔV, to an edge 1A of an edge-shaped spectacle lens 1 . For this purpose, the edge thickness Δx at the application site can be detected by means of a measuring device (not shown) and transmitted to the control device 2 , which actuates the dispensing device of the application unit 3 , for example a nozzle.

[0045] here, Figure 1B Illustrates that, in relation to Figure 1A A smaller droplet volume ΔV is formed with a smaller spectacle lens thickness. Furthermore, it is shown that the spectacle lens 1 can be rotated about the optical axis 4 during application.

[0046] according to temporal succession Figure 1C and 1D In particular, the applied droplets or strips 5 of the material forming the functional layer 5A spread out over the entire coverage of the edge 1A.

[0047] Thus, according to Figure 1E Various shapes of the functional layer...

Abstract

A spectacle lens (1) which has, on its outer edge (1A) and / or on its front or rear surface (1 B), at least one functional layer (5A), the at least one functional layer (5A, 6, 7, 13, 14, 15, 16, 19, 20, 22) being formed by a substance that is applied in liquid form to the edge (1A) and / or the front or rear surface (1 B) of the spectacle lens (1), is integrally bonded to the glass and is chemicallycured or radiation-cured, and said at least one functional layer (5A, 6, 7, 13, 14, 15, 16, 19, 20, 22) having an optical function, magnetic function or electrical or electronic function. Also a method for producing a spectacle lens, in particular machined from a lens blank, wherein a material is applied in liquid form to the edge (1A) and / or the front or rear surface (1 B) of the edged spectaclelens (1) and is chemically cured or radiation-cured, said material forming at least one functional layer (5A, 6, 7, 13, 14, 15, 16, 19, 20, 22) on the glass, which functional layer having an opticalfunction, magnetic function or electrical or electronic function.

Description

technical field [0001] The invention relates to a spectacle lens having at least one functional layer on the outer edge and / or on the front or back, wherein the at least one functional layer is applied in liquid form to the edge and / or the front / back of the spectacle lens It consists of a material that is hardened chemically or by radiation, in particular the material is bonded to the spectacle lens after hardening. [0002] Furthermore, the invention also relates to a method for producing spectacle lenses, wherein a material in liquid form is applied to the edge and / or the front / rear side of the edged spectacle lens and the material is decomposed chemically or by radiation. hardening. Preferably, a material-bonded connection is produced here between the materials of the spectacle lens, ie in particular between glass or transparent plastic and the applied material. Background technique [0003] Such a spectacle lens and a method for its production are known from the applic...
