Optical lens or glass having a label and/or marking on the front surface and/or rear surface
View Patent ↗The invention relates to an optical lens or glass with an identification and/or marking on the front and/or rear surface. The inventive lens or glass with an identification and/or marking on the front and/or back surface is characterized by an identification and/or marking which consists of a plurality of elements, each element causing a spectral dispersion of the incident light and reflected light.
1. An optical lens or glass having at least one of a label and a marking on at least one of a front surface thereof and a rear surface thereof, wherein the at least one of the label and the marking comprises elements configured to cause a spectral dispersion of incident and reflected light, and the elements being regular bodies that comprise at least two faces and that protrude from at least one of the front surface and the rear surface.
2. The lens as claimed in claim 1 , wherein the at least one of the label and marking is transparent.
3. The lens as claimed in claim 1 , wherein the elements are prisms.
4. The lens as claimed in claim 3 , wherein the at least one of the label and marking is transparent.
5. The lens as claimed in claim 1 , wherein the faces of the regular bodies are transparent.
6. The lens as claimed in claim 4 , wherein the at least one of the label and marking is transparent.
7. The lens as claimed in claim 6 , wherein the elements are prisms.
8. The lens as claimed in claim 1 , wherein a region to which at least one of the label and the marking is applied defines an area not in excess of 2.00 cm 2 .
9. The lens as claimed in claim 8 , wherein the at least one of the label and marking is transparent.
10. The lens as claimed in claim 9 , wherein the elements are prisms.
11. The lens as claimed in claim 10 , wherein the faces of the regular bodies are transparent.
12. The lens as claimed in claim 1 , wherein the lens is a spectacle lens.
13. A method of producing a lens, including spectacle lenses and watch glasses, comprising: casting polymerizable material into a mold that has at least one casting surface for producing a corresponding optical surface of the lens, wherein the casting surface has at least one of recesses and elevations that are complementary to elements comprising at least one of the marking and label such that the elements protrude from at least one of a front surface and a rear surface of the lens.
14. The method as claimed in claim 13 , further comprising milling the complementary recesses are one of milled into the casting surface and engraved.
