110 in an embodiment coupling 214 between electrodes 204 and power source 201 are physical leads another example of coupling 214 is wireless signals which are sent for example by an rf transmitter fig3 a illustrates an exemplary cross section of reservoir 202 in its inflated state 300 within housing 106 also shown are electrodes 204 woven through the thickness of reservoir 202 and a fluid 302 filling the volume within reservoir 202 upon generation of an electric field to electrodes 204 with a first polarity reservoir 202 enters a constricted state 304 as exemplified by fig3 b a compressive force 306 on all sides of reservoir 202 causes reservoir 202 to constrict upon constricting fluid 302 is forced from reservoir 202 through connecting tube 208 and into fluid cavity 206 thus increasing the curvature of lens module 104 it can be understood that the strength of compressive force 306 is proportional to the strength of the generated electric field one of ordinary skill in the art will recognize that different electric potentials supplied to electrodes 204 will result in different constricted states 304 allowing for a customizable curvature change of lens module 104 using a variable applied potential in an embodiment generation of an electric field to electrodes 204 with a second polarity opposite that of the first polarity will cause reservoir 202 to flex to an inflated state 300.
