1. A device comprising:
a first transparent conductive layer;
a second transparent conductive layer;
at least one electro-chromic layer disposed between the first transparent conductive layer and the second transparent conductive layer; and
an electrolyte layer disposed between the first transparent conductive layer and the second transparent conductive layer and in contact with the at least one electro-chromic layer,
wherein the electrolyte layer comprises at least one of an interpenetrating polymeric network or a semi-interpenetrating polymeric network,
wherein:
the interpenetrating polymeric network comprises at least a hard/tough polymer network interwoven with a soft/flexible polymer network wherein the hard/tough polymer network includes a polyvinilidene difluoride (PVDF)-based polymer or copolymer and the soft/flexible polymer network includes an acrylate/methacrylate polymer blend; and
the semi-interpenetrating polymeric network comprises at least one polymer network and at least one linear or branched polymer interwoven in the at least one polymer network wherein the semi-interpenetrating polymeric network is a mix of a hard/tough polymer and a soft/flexible polymer wherein the hard/tough polymer includes a polyvinilidene difluoride (PVDF)-based polymer or copolymer and the soft/flexible polymer includes an acrylate/methacrylate polymer blend;
wherein the first transparent conductive layer, the at least one electro-chromic layer, the electrolyte layer, and the second transparent conductive layer are disposed on a member of the group consisting of a lens blank and a semi-finished lens blank; and
wherein the electrolyte layer has a conductivity greater than 10−4 S/cm.
