Abstract
Ophthalmic lenses are described including a deformable layer and a deformable membrane disposed opposite the deformable layer. The lens is configured with at least two regions of adjustable optical power, such as by using a patterned electrode which is used to drive the membrane move axially along an optical path of the lens. A surface of the deformable layer is configured to expand and/or contract based on movement of the membrane along the optical path of the lens, such as by bonding one side of the deformable layer to the membrane and bonding the other side to a fixed optical element layer.
