Claims16
A lens that includes an electroactive region where an optical characteristic changes by electric control, the lens comprising:
- a first transparent substrate;
- a second transparent substrate disposed facing the first transparent substrate;
- and
- an intermediate layer disposed between the first transparent substrate and the second transparent substrate and including a mark including information,
- wherein:
- the first transparent substrate is disposed on a position closer to a user of the lens than the second transparent substrate in a state where the lens is in use;
- the intermediate layer includes a liquid crystal layer in a position which corresponds to the electroactive region;
- and
- the mark is placed on a position closer to the second transparent substrate than the liquid crystal layer in the thickness direction of lens.
A lens that includes an electroactive region where an optical characteristic changes by electric control, the lens comprising:
- a first transparent substrate;
- a second transparent substrate disposed facing the first transparent substrate;
- and
- an intermediate layer disposed between the first transparent substrate and the second transparent substrate and including a mark including information,
- wherein:
- the intermediate layer includes a first electrode and a second electrode,
- the first electrode includes a first auxiliary electrode which extends inward from the outer edge of lens,
- the second electrode includes a second auxiliary electrode which extends inward from the outer edge of lens,
- the first auxiliary electrode and the second auxiliary electrode are arranged so as to be adjacent to each other in a front view of the lens, and
- at least a part of the mark is placed between the first auxiliary electrode and the second auxiliary electrode in the front view of the lens.
