Abstract
A meniscus shaped lens module comprises one or more structures that decrease an amount of pressure or force to move one or more surfaces of the lens module and increase a separation distance of anterior and posterior surfaces of the module in order to provide an increase in optical power. A lens structure of the module comprises one or more of a pattern of a surface of a central chamber, a meniscus, a reduced diameter or a soft material in order to provide increased amounts of curvature of an outer contact lens surface with decreased amounts of pressure. The pattern can be formed in one or more of many ways, and may comprise one or more of folds, patterning, bellows or concertinaed surface of an optically transmissive material having a substantially uniform thickness such as a sheet of a membrane material.
