Abstract

An ophthalmic lens incorporating an array of microlenses.

First claim

What is claimed is:

1 . An ophthalmic lens comprising:
a base lens substrate having a front optical surface and a back optical surface; and an array of microlenses incorporated into at least a portion of the base lens substrate.

2 . The lens of claim 1 wherein the base lens substrate is a cast monomer.

3 . The lens of claim 1 wherein the array of microlenses is distributed across at least a portion of the front optical surface.

4 . The lens of claim 1 wherein the array of microlenses is distributed across at least a portion of the back optical surface.

5 . The lens of claim 1 wherein the array of microlenses comprises a first microlens formed of a first material and a second microlens formed of second material that is distinct from the first material.

6 . The lens of claim 1 wherein the array of microlenses comprises microlenses having optical surfaces that have different geometries.

7 . The lens of claim 1 wherein the array of microlenses comprises microlenses having optical surfaces that have the same geometries positioned in different orientations.

8 . The lens of claim 1 wherein the array of microlenses comprises a same material from which the base lens substrate is formed.

9 . The lens of claim 1 wherein the array of microlenses comprises a different material from which the base lens substrate is formed.

10 . The lens of claim 1 wherein the array of microlenses comprises microlenses formed of a plurality of layers of different material.

11 . A multifocal ophthalmic lens comprising:
a base lens substrate having a front optical surface and a back optical surface; and an array of microlenses incorporated into at least a portion of the base lens substrate, the array of microlenses comprising a first plurality of microlenses having a first optical power and a second plurality of microlenses having a second optical power different from the first optical power.

12 . The lens of claim 11 wherein the first plurality of microlenses comprises a material having a refractive index that is distinct from a refractive index of the second plurality of microlenses.

13 . The lens of claim 11 wherein array of microlenses comprises a different material from which the base lens substrate is formed.

14 . The lens of claim 11 wherein the first plurality of microlenses and the second plurality of microlenses are distributed evenly across an entirety of the array of microlenses.

15 . A method for forming an ophthalmic lens comprising:
obtaining a base lens substrate; and incorporating an array of microlenses across at least a portion of the base lens substrate.

16 . The method of claim 15 wherein the step of incorporating an array of microlenses across at least a portion of the base lens substrate comprises etching the array of microlenses into an optical surface of the base lens substrate.

17 . The method of claim 15 wherein the step of incorporating an array of microlenses across at least a portion of the base lens substrate comprises etching at least a portion of a first material layer of the base lens substrate off of a second different material layer of the base lens substrate.

18 . The method of claim 15 wherein the step of incorporating an array of microlenses across at least a portion of the base lens substrate comprises depositing the array of microlenses on an optical surface of the base lens substrate by vapor deposition.

19 . The method of claim 15 wherein the step of incorporating an array of microlenses across at least a portion of the base lens substrate comprises depositing the array of microlenses on an optical surface of the base lens substrate by photolithography.

20 . The method of claim 15 wherein the step of incorporating an array of microlenses across at least a portion of the base lens substrate comprises incorporating a film comprising the array of microlenses in to the base lens substrate.
