The present provides deformable molds and methods for manufacturing ophthalmic lenses using deformable molds. The molds of the invention may be used in the custom manufacture of ophthalmic lenses.

Deformable molds and methods for their use in the manufacture of ophthalmic lenses

An actuator for a deformable optical component includes a stack of ferroelectric layers, a plurality of electrodes for applying a voltage across each layer; every other electrode extending to an associated first conductor path and interstitial electrodes extending to an associated second conductor path the first conductor path or receiving a first conductor lead, the second conductor path for receiving a second conductor lead to contact the respective electrodes.

Actuator for deformable optical component

A high authority deformable optical system includes an optical faceplate; a base; a plurality of circuit boards, each including at least one actuator; each actuator engaging at one end the base and at the other the optical faceplate; each printed circuit board providing conductor paths between its associated actuators and a connector device for selectively energizing the actuators.
