1. A chromism light-adjusting lens, comprising:
a plurality of chromism films, each of the chromism films comprising a first substrate layer and a second substrate layer that are transparent, and a liquid crystal layer disposed between the first substrate layer and the second substrate layer; and
a power supply device for supplying power to the each of the chromism films,
wherein the each of the chromism films further comprises a dichroic dye molecule layer, each of dichroic dye molecules of the dichroic dye molecule layer being disposed on a surface of one of liquid crystal molecules of the liquid crystal layer, and a direction in which the liquid crystal molecules are arranged is adjustable with a voltage applied to the each of the chromism films by the power supply device;
the first substrate layer comprises a first flexible substrate, a first conductive film layer and a first alignment layer which are laminated;
the second substrate layer comprises a second flexible substrate, a second conductive film layer and a second alignment layer which are laminated;
the power supply device is electrically connected to the first conductive film layer and the second conductive film layer;
the liquid crystal layer is sandwiched between the first alignment layer and the second alignment layer; and
the first alignment layer and the second alignment layer of the each of the chromism films are configured to align the liquid crystal molecules of the each of the chromism films in a first direction, and the first alignment layer and the second alignment layer of one of the chromism films adjacent to the each of the chromism films are configured to align the liquid crystal molecules of the one of the chromism films in a second direction perpendicular to the first direction.
