1. A device comprising a fluid lens, wherein the fluid lens comprises:
a membrane that includes a membrane polymer and a polymer additive extending through the membrane polymer, wherein the membrane polymer and the polymer additive include different polymers;
a peripheral structure positioned around the membrane;
a substrate;
a fluid located within an enclosure formed at least in part by the membrane and the substrate; and
a plurality of support structures, wherein each support structure interconnects the substrate with a portion of the peripheral structure and allows a movement of the portion of the peripheral structure to adjust a focal length of the fluid lens,
wherein:
the membrane polymer comprises a urethane polymer;
the polymer additive comprises a fluoroacrylate polymer; and
the polymer additive forms a polymer network that extends through at least a portion of the membrane polymer.
