LIQUID MENISCUS LENS INCLUDING VARIABLE VOLTAGE ZONES

摘要

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 multiple voltage zones that may have variable voltages applied across the zones. Embodiments may also include a lens of suitable size and shape for inclusion in a contact lens.

主权项

1. 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 forming a meniscus therebetween; and a meniscus wall having multiple voltage zones formed in one or both of the front lens and back lens and bordering the meniscus formed between the saline solution and oil, wherein the voltage zones are formed by gaps in a conductive coating on the meniscus wall and at least two of the voltage zones are capable of receiving a different applied voltage.
