Abstract
According to some aspects, an adaptive lens is provided. One such adaptive lens comprises at least one fluid-filled chamber located within an optical and/or acoustic path of the lens, and at least one elastomeric and substantially optically and/or acoustically transparent membrane, located within an optical and/or acoustic path of the lens and at least partially bounding one or more of the at least one fluid-filled chambers, wherein one or more of the at least one membranes is configured such that a shape of the membrane is altered upon receipt of an electric field. Some aspects provide a method of producing a lens comprising providing at least one chamber bounded at least in part by first and second membranes, and providing a fluid into the at least one chamber such that the fluid is located within an optical and/or acoustic path of the lens.
