Abstract
This invention describes Ophthalmic Devices with media inserts that have nanostructured Metasurface elements upon or within them. In some embodiments passive ophthalmic devices of various kinds may be formed. Methods and devices for active ophthalmic devices based on Metasurface structures may also be formed.
Claims20
An Ophthalmic device comprising:
- an insert device, wherein at least a portion of a surface on the insert device has metallic features upon it, wherein the metallic features are arranged in a pattern with a periodicity that is less than a distance equal to a targeted wavelength of light.
An Ophthalmic device comprising:
- an insert device, wherein at least a portion of a surface on the insert device has metallic features upon it, wherein the metallic features are arranged in a repeating pattern whose periodicity is less than a distance equal to a targeted wavelength of light;
- a dielectric layer upon the metallic features;
- and
- a combination of immiscible fluids in proximity to the dielectric layer, wherein at least one of the immiscible fluids includes one or more of a metallic nanosphere or a metallic nanorod.
