Ophthalmic lens with graded microlenses

1. An ophthalmic spectacle lens comprising:

a base lens substrate of a spectacle lens having a front surface and a back surface;

said base lens of a spectacle lens having a low-frequency curve;

a plurality of microlenses disposed on at least one of said front surface and said back surface of said base lens substrate of a spectacle lens;

each of said microlenses having a static local curvature;

said local curvature of at least one of said plurality of microlenses being different than the low-frequency curve of said base lens of a spectacle lens.

2. The ophthalmic spectacle lens according to claim 1 , wherein said plurality of microlenses are disposed on said front surface.

3. The ophthalmic spectacle lens according to claim 1 , wherein an effective curvature power of said lens is obtained by adding a power associated with said low-frequency curve to a power associated with said local curvature.

4. The ophthalmic spectacle lens according to claim 1 , wherein said plurality of microlenses are semi-circular.

5. The ophthalmic spectacle lens according to claim 1 , wherein said local curvature of some of the plurality of microlenses is the same as the low-frequency curve of said base lens.

6. The ophthalmic spectacle lens according to claim 1 , wherein the geometry of the microlens is the property that primarily functions to define the optical power of the microlens.

7. The ophthalmic spectacle lens according to claim 1 , wherein a power associated with said low-frequency curve is zero.

8. The ophthalmic spectacle lens according to claim 1 , wherein said plurality of microlenses are located over a substantial entirety of a front surface of said base lens substrate.

9. The ophthalmic spectacle lens according to claim 1 , wherein a plurality of said plurality of microlenses has a concave effective curvature.

10. The ophthalmic spectacle lens according to claim 1 , wherein optical power of said microlens is primarily defined by a refractive index of said microlens.
