Abstract

A method for producing a coating on a surface of a coated or uncoated spectacle lens includes: applying a masking on a partial region of the surface of the coated or uncoated spectacle lens, applying at least one layer on the surface, and removing the masking and the at least one layer applied on the masking from the partial region of the surface. The masking is applied with a matrix printing method. A spectacle lens produced by the method is also disclosed.

First claim

The invention claimed is:

1. A method for producing a coating on a surface of a coated or uncoated spectacle lens, the method comprising:
applying a masking on a partial region of a surface of the coated or uncoated spectacle lens with a matrix printer;
applying a layer on the masking and on a remaining region of the surface of the coated or uncoated spectacle lens; and
removing the masking and a portion of the layer applied on the masking from the partial region of the surface of the coated or uncoated spectacle lens,
wherein a proportion of the partial region of the surface of the coated or uncoated spectacle lens is 20% or less relative to an entire surface region of a finished, edged spectacle lens made from the coated or uncoated spectacle lens, and
wherein the layer is a part of an antireflection layer having a multilayered construction.

2. The method as claimed in claim 1 , wherein the matrix printer is an inkjet printer.

3. The method as claimed in claim 1 , wherein the layer is a first layer, the method further comprising at least one of:
applying a second layer on the surface of the coated or uncoated spectacle lens before applying the masking, or
applying the second layer on the partial region of a surface of the coated or uncoated spectacle lens and on the layer on the remaining region of the surface of the coated or uncoated spectacle lens after removing the masking from the partial region.

4. The method as claimed in claim 1 , wherein the removal of the masking comprises at least one of:
wiping away the masking, or
dipping the coated or uncoated spectacle lens into a solvent, wherein the solvent includes acetone.

5. The method as claimed in claim 1 , wherein the layer has a reflection maximum in a visible spectral range or in a non-visible spectral range.

6. The method as claimed in claim 1 , wherein the coated or uncoated spectacle lens is a lens blank, a spectacle lens semifinished product, or a finished spectacle lens.

7. The method as claimed in claim 1 , wherein the masking of the partial region comprises a radiation-curable inkjet ink.

8. A spectacle lens produced by the method as claimed in claim 1 .

9. The spectacle lens as claimed in claim 8 , wherein a proportion of the partial region is 0.05% to 17% relative to the entire surface region of the finished, edged spectacle lens made from the coated or uncoated spectacle lens.

10. The spectacle lens as claimed in claim 8 , wherein the partial region has a shape of a pattern.

11. A spectacle lens comprising:
a layer applied selectively on a partial region of a surface of the spectacle lens,
wherein a boundary line between the partial region and an adjoining partial region in which the layer is not applied is defined by a printing with a matrix printer,
wherein the layer applied selectively on the partial region of the spectacle lens defines a reflection image,
wherein a proportion of the partial region of the spectacle lens provided with the reflection image is 20% or less relative to an entire surface of a finished, edged spectacle lens made from the spectacle lens, and
wherein the layer applied selectively on the partial region of the spectacle lens is a part of a multilayered construction.

12. The spectacle lens as claimed in claim 8 , wherein the spectacle lens is a lens blank, a spectacle lens semifinished product, or a finished spectacle lens.

13. A method for producing a coating on a surface of a coated or uncoated spectacle lens, the method comprising:
applying a masking on a partial region of a surface of the coated or uncoated spectacle lens with a matrix printer;
applying a layer on the masking and on a remaining region of the surface of the coated or uncoated spectacle lens; and
removing the masking and a portion of the layer applied on the masking from the partial region of the surface of the coated or uncoated spectacle lens,
wherein a proportion of the partial region of the surface of the coated or uncoated spectacle lens is 10% to 30% relative to an entire surface region of a finished, edged spectacle lens made from the coated or uncoated spectacle lens,
wherein the partial region is a circumferential edge region arranged at a constant distance from a boundary of the surface, and
wherein the layer is a part of an antireflection layer having a multilayered construction.

14. A spectacle lens comprising:
a layer applied selectively on a partial region of a surface of the spectacle lens,
wherein a boundary line between the partial region and an adjoining partial region in which the layer is not applied is defined by a printing with a matrix printer,
wherein the layer applied selectively on the partial region of the spectacle lens defines a reflection image,
wherein a proportion of the partial region of the surface of the coated or uncoated spectacle lens is 10% to 30% relative to an entire surface region of a finished, edged spectacle lens made from the coated or uncoated spectacle lens,
wherein the partial region is a circumferential edge region arranged at a constant distance from a boundary of the surface, and
wherein the layer is a part of a multilayered construction.

15. The spectacle lens as claimed in claim 10 , wherein the pattern is a logo, a letter, a negative of the logo, or a negative of the letter.

16. The spectacle lens as claimed in claim 11 , wherein the boundary line has a pixel structure.

17. The spectacle lens as claimed in claim 14 , wherein the boundary line has a pixel structure.
