Embodiment Construction

[0022] The present invention provides a liquid meniscus lens having at least one of a front curve lens and a back curve lens defining a meniscus cavity of the liquid meniscus lens.

[0023] the term

[0024] In this specification and claims related to the present invention, the definitions of various terms used are as follows:

[0025] Contact Angle: The angle at which the oil / brine solution interface (also known as the liquid meniscus boundary) contacts the meniscus wall. For a linear meniscus wall, the contact angle is the angle measured between the meniscus wall and a line tangent to the liquid meniscus boundary where the liquid meniscus boundary contacts the meniscus wall. For a curved meniscus wall, the contact angle is the angle measured between a line tangent to the meniscus wall and the liquid meniscus boundary when they are in contact.

[0026] Liquid Meniscus Boundary: The arcuate surface interface between the saline solution and the oil. Generally, this surface...

Abstract

The present invention relates generally to a liquid meniscus lens with a meniscus wall. The meniscus lens may include an arcuate front curve and back curve lens. Some specific embodiments include a liquid meniscus lens with a meniscus wall essentially in the shape of multiple segments of a torus concave from the optical axis. Embodiments may also include a lens of suitable size and shape for inclusion in a contact lens.
