Abstract
Optical devices having a dynamic aperture and/or an apodization mask are provided. The aperture and/or mask may be provided by one or more electro-active elements, and may be used in an ophthalmic device that that is spaced apart from but in optical communication with an intraocular lens, a corneal inlay, a corneal onlay, or a spectacle lens that provide an optical power.
Claims32
An ophthalmic device comprising:
- an apodization mask comprising an electro-active, transparent substrate;
- wherein the substrate has at least one optical transmission property that is alterable by electrical activation.
An ophthalmic device, comprising:
- an apodization mask comprising a transparent substrate;
- wherein the substrate has at a refractive index gradient of at least 0.01 units/mm in at least one meridian.
An ophthalmic device comprising:
- a substrate;
- and
- a liquid crystal layer having a variable optical transmission of about 30%-99% upon electrical activation of the liquid crystal layer.
