Abstract
A method includes providing an ophthalmic lens having a prescribed optical power, the ophthalmic lens having a surface having a base curvature corresponding to the prescribed optical power, and exposing a material at the surface to laser radiation sufficient to locally reshape the material to form a plurality of lenslets on the surface. The lenslets each have a corresponding optical power that differs from the prescribed optical power of the ophthalmic lens.
Claims18
1-20. (canceled)
A device, comprising:
- an ophthalmic lens having a prescribed optical power, the ophthalmic lens having a surface having a base curvature corresponding to the prescribed optical power;
- one or more optical elements formed in or supported by the surface, each optical element providing an optical effect different from the prescribed optical power;
- and
- one or more layers of material coated on the surface, each optical element being located at a discontinuity in the one or more layers of material.
1 more element
A method, comprising:
- coating a layer of a first material on a surface of an ophthalmic lens;
- exposing the layer of the first material to laser radiation sufficient to remove the first material from discrete locations of the layer and form pits in the surface of the ophthalmic lens at those locations;
- after exposing the layer of the first material, depositing a second material over the layer of the first material, wherein the second material fills the pits in the surface of the ophthalmic lens;
- and
- after depositing the second material, removing the layer of the first material from the surface of the ophthalmic lens to provide a pattern of spaced apart regions of the second material on the surface of the ophthalmic lens.
2 more elements
A method, comprising:
- exposing discrete locations on a surface of an ophthalmic lens to laser radiation sufficient to form pits in the surface of the ophthalmic lens at those locations;
- and
- depositing a first material in the pits in the surface of the ophthalmic lens to provide light scattering centers or lenslets in the lens.
