Abstract

A spectacle lens has a transparent substrate and at least one HOE-capable polymer layer arranged on the transparent substrate. The at least one HOE-capable polymer layer is suitable for forming a holographic optical element. Related methods and apparatus are described.

First claim

The invention claimed is:

1. A method for producing a spectacle lens comprising a holographic optical element-capable (HOE-capable) polymer layer, wherein the HOE-capable polymer layer is suitable for forming a holographic optical element, wherein the method comprises:
coating of a transparent substrate of the spectacle lens with a precursor of the HOE-capable polymer layer, and
converting the precursor, which is arranged on the transparent substrate, for forming the HOE-capable polymer layer; and
performing spatially resolved exposure of the HOE-capable polymer layer to form the holographic optical element,
wherein the performing the spatially resolved exposure comprises:
obtaining geometric data describing a geometry of the transparent substrate of the spectacle lens; and
based on the geometric data, determining control data describing an intensity and a phase of the spatially resolved exposure,
wherein the performing the spatially resolved exposure is carried out with the control data.

2. The method of claim 1 , wherein the method further comprises:
applying at least one of a hard layer, an antireflective layer, or a clean-coat layer to the HOE-capable polymer layer.

3. The method of claim 2 ,
wherein the performing the spatially resolved exposure of the HOE-capable polymer layer takes place after applying at least one of the hard layer, the antireflective layer, and the clean-coat layer.

4. The method of claim 1 , wherein the precursor and/or the HOE-capable polymer layer comprise a photoreactive component and/or an HOE polymer and/or a polymer matrix, and wherein the method further comprises:
applying a primer layer comprising the polymer matrix and/or a further polymer to the transparent substrate.

5. A method for producing a spectacle lens comprising a holographic optical element-capable (HOE-capable) polymer layer, wherein the HOE-capable polymer layer is suitable for forming a holographic optical element, wherein the method comprises:
coating of a carrier with a precursor of the HOE-capable polymer layer;
converting the precursor, which is arranged on the carrier, to obtain the HOE-capable polymer layer;
performing fixation of the HOE-capable polymer layer on a transparent substrate of the spectacle lens; and
performing spatially resolved exposure of the HOE-capable polymer layer to form the holographic optical element,
wherein the performing the spatially resolved exposure comprises:
obtaining geometric data describing a geometry of the transparent substrate of the spectacle lens; and
based on the geometric data, determining control data describing an intensity and a phase of the spatially resolved exposure,
wherein the performing the spatially resolved exposure is carried out with the control data.

6. The method of claim 5 ,
wherein the performing the fixation of the HOE-capable polymer layer is carried out by gluing and/or laminating.

7. The method of claim 6 , wherein the method, after the fixation of the HOE-capable polymer layer on the transparent substrate, further comprises:
removing the carrier from the HOE-capable polymer layer.

8. The method of claim 5 ,
wherein the performing the spatially resolved exposure of the HOE-capable polymer layer takes place before the fixation of the HOE-capable polymer layer on the transparent substrate.

9. A method for producing a spectacle lens comprising a holographic optical element-capable (HOE-capable) polymer layer, wherein the HOE-capable polymer layer is suitable for forming a holographic optical element, wherein the method comprises:
coating of a carrier with a precursor of the HOE-capable polymer layer;
converting the precursor, which is arranged on the carrier, to obtain the HOE-capable polymer layer;
performing spatially resolved exposure of the HOE-capable polymer layer to form the holographic optical element; and
performing fixation of the HOE-capable polymer layer on a transparent substrate of the spectacle lens,
wherein the performing the spatially resolved exposure of the HOE-capable polymer layer takes place before the performing the fixation of the HOE-capable polymer layer on the transparent substrate, and
wherein the performing the spatially resolved exposure comprises:
obtaining geometric data describing a geometry of the transparent substrate of the spectacle lens, and
depending on the geometric data, determining control data describing an intensity and a phase of the spatially resolved exposure,
wherein the performing the spatially resolved exposure is carried out with the control data.
