Abstract

A phase-adjusting element configured to provide substantially liquid-invariant extended depth of field for an associated optical lens. One example of a lens incorporating the phase-adjusting element includes the lens having surface with a modulated relief defining a plurality of regions including a first region and a second region, the first region having a depth relative to the second region, and a plurality of nanostructures formed in the first region. The depth of the first region and a spacing between adjacent nanostructures of the plurality of nanostructures is selected to provide a selected average index of refraction of the first region, and the spacing between adjacent nanostructures of the plurality of nanostructures is sufficiently small that the first region does not substantially diffract visible light.

Claims (26)

1. A lens comprising a lens surface providing a refractive power, the lens surface comprising a plurality of concentric annular regions substantially entirely filled by an array of a plurality of optical elements formed on the surface thereof, with each adjacent pair of the plurality of concentric annular regions separated by a region devoid of optical elements, wherein each of the optical elements increases a thickness of the lens at the optical element, and wherein adjacent optical elements in each of the arrays are uniformly distributed and located less than 400 nm apart.

2. The lens of claim 1 , wherein the lens surface comprises a central substantially circular region devoid of optical elements.

3. The lens of claim 1 , wherein each of the optical elements increases a thickness of the lens at the optical element by at least 100 nm.

4. The lens of claim 1 , wherein each of the optical elements is integral with the lens.

5. The lens of claim 1 wherein the plurality of concentric annular regions do not provide refractive optical power over the refraction of the lens.

6. The lens of claim 1 wherein the plurality of concentric annular regions do provide refractive optical power over the refraction of the lens.

7. The lens of claim 1 , wherein the plurality of optical elements are dome-shaped.

8. The lens of claim 1 , wherein the plurality of optical elements and the lens comprise the same material.

9. The lens of claim 1 , wherein the plurality of optical elements and the lens comprise different materials.

10. The lens of claim 1 , wherein the plurality of optical elements are optically transparent.

11. A spectacle lens comprising:

a lens comprising a lens surface;

a modulated relief on the lens surface, the modulated relief comprising a plurality of concentric annular regions having an array of a plurality of optical elements formed on the surface thereof, with each adjacent pair of the plurality of concentric annular regions separated by a region devoid of optical elements;

wherein:

each of the optical elements increases a thickness of the spectacle lens at the optical element;

adjacent optical elements in each of the arrays are uniformly distributed and located less than 400 nm apart; and

14. The spectacle lens of claim 11 , wherein each of the optical elements is integral with the lens.

15. The spectacle lens of claim 11 , wherein the plurality of concentric annular regions do not provide refractive optical power over the refraction of the spectacle lens.

16. The spectacle lens of claim 11 , wherein the plurality of concentric annular regions do provide refractive optical power over the refraction of the spectacle lens.

17. The spectacle lens of claim 11 , wherein the plurality of optical elements are dome-shaped.

18. The spectacle lens of claim 11 , wherein the plurality of optical elements and the lens comprise the same material.

19. The spectacle lens of claim 11 , wherein the plurality of optical elements and the lens comprise different materials.
