Optical lens, in particular for use as a spectacle lens

摘要

An optical lens (10), in particular for use as a spectacle lens, comprises a first lens element (18) and at least one second lens element (20), wherein the first lens element (18) and the second lens element (20) at least partly act together in an achromatic fashion. The second lens element (20) is configured as at least one lens segment (26) that is only arranged in a margin region (28) of the first lens element (18). Furthermore, a method for producing the optical lens (10) is described.

主权项

1. A spectacle lens comprising a first lens element and a second lens element,
wherein the first lens element and the second lens element achieve an achromatic effect in a margin region of the first lens element, wherein the second lens element is manufactured from a material, the Abbe number and/or refractive index of which differs from the Abbe number and/or the refractive index of the material of the first lens element, wherein the second lens element is configured as precisely one lens segment that is only arranged in the margin region of the first lens element, wherein there is only the first lens element in a central region, wherein the precisely one lens segment extends along the margin region of the first lens element over the entire circumference, wherein a rear side of the spectacle lens is formed by a rear side of the first lens element and a rear side of the lens segment, and wherein the spectacle lens is only achromatized in the margin region.
