Abstract
The present invention relates generally to an arcuate liquid meniscus lens with a meniscus wall. Some specific embodiments include a liquid meniscus lens with a meniscus wall essentially in the shape of a conical frustum with portions of gradient thickness dielectric. Other embodiments may include a cylindrical shape meniscus wall. Embodiments may also include a lens of suitable size and shape for inclusion in a contact lens.
Claims31
An optical lens comprising:
- a front lens comprising a front lens exterior surface and a front lens interior surface;
- a back lens comprising a back lens interior surface and a back lens exterior surface said back lens positioned proximate to said front lens such that said front lens interior surface and said back lens interior surface form a cavity therebetween;
- a volume of saline solution and oil contained within the cavity formed between said front lens interior surface and said back lens interior surface, said volume of saline solution and oil comprising a meniscus therebetween;
- a meniscus wall comprising a first portion with a first dielectric thickness and a second portion with a second dielectric thickness, wherein the first dielectric thickness is greater than the second dielectric thickness and each of the first portion and the second portion border the meniscus formed between the saline solution and oil;
- and
- a conductive coating on at least a portion of said meniscus wall wherein the volume of oil comprises density within about 10% of a density of the saline solution.
