1. An ophthalmic lens comprising:
a lens body having a chamber therein, at least a portion of the lens body being flexible, the lens body having a lens body index of refraction;
a reservoir coupled with the lens body and defining a reservoir volume that is fluidically connected with the chamber of the lens body, the reservoir comprising a plurality of heat sensitive structures that change shape from a first, substantially hemispherical shape to a second, substantially flattened shape responsive to a threshold temperature; and
an optical fluid residing in the chamber and the reservoir, the optical fluid having an optical fluid index of refraction, a change in the reservoir volume occur by flowing a portion of the optical fluid between the reservoir and the chamber such that the at least the portion of the lens body undergoes a shape change corresponding to a base power change,
wherein:
a first portion of the plurality of heat sensitive structures has a first orientation such that the change from the first, substantially hemispherical shape to the second, substantially flattened shape increases the reservoir volume; and
a second portion of the plurality of heat sensitive structures has a second orientation such that the change from the first, substantially hemispherical shape to the second, substantially flattened shape decreases the reservoir volume.
