Abstract
The invention relates to a controllable lens with variable optical power. The lens comprises a first and second cover members (), a transparent, deformable, non-fluid body () sandwiched between the first and second i transparent cover members, so that the first and second transparent cover members and non-fluid body constitute a lens, one or more actuators arranged to provide displacement in a direction along the optical axis, and one or more elastic elements (__) connecting the actuator displacement elements with the first cover member, wherein at least a portion of each of the one or more elastic elements is arranged to deform elastically in response to a relative radial displacement between the first transparent cover member and the actuator displacement elements. A first stiffness in a radial direction of each of the one or more elastic elements is smaller than a second stiffness in the direction of the optical axis of each of the one or more elastic elements.
