1. An ophthalmic device comprising:
a lens comprising a plurality of optical zones each having an optical power optimized for one or more focal lengths;
one or more focus sensors; and
a tunable apodization mask positioned within at least a portion of at least one of the plurality of optical zones; wherein tunable apodization mask is configured to vary in response to focus data from the one or more focus sensors, an opacity of the tunable apodization mask to increase or decrease a transmissivity of light through at least one of the plurality of optical zones to effect a change in optical power of the ophthalmic device; wherein the tunable apodization mask comprises an electrochromic device comprising:
an inner conductive layer and an outer conductive layer;
a first ion transport group; and
a second ion transport group;
wherein the first and second ion transport groups are interposed between the inner and outer conductive layers in opposite orientations relative to the inner and outer conductive layers such that an electrical bias applied to the inner and outer conductive layers causes the one of the first and second ion transport groups to function in a transparent state and the other of the first and second ion transport groups to function in an opaque state.
