DIELECTRIC ELECTRO-ACTIVE POLYMER CONTACT LENSES

摘要

An ophthalmic device is described that includes a frame and an optically active component comprising a bistable dielectric electroactive polymer. The bistable dielectric electroactive polymer changes shape when exposed to a sufficiently strong electric field and does not completely revert to its former shape when the electric field is deactivated. The refractive properties of the ophthalmic devices described herein are adjusted by exposing the devices to electric fields.
