Abstract

This eyewear is provided with: a lens which has an electric element, an electrode of the electric element being disposed at an edge of the lens; a frame which has a control unit for controlling the electric element, and which holds the lens; a conductive wire which has a long conductor surface that extends along and facing such edge, and which is connected to the control unit; and a conductive piece which extends along and facing such edge and which comes into contact with the electrode and the conductor surface.

First claim

What is claimed is:

1. An eyewear, comprising:
a lens including an electric element and an edge portion provided with an electrode of the electric element;
a frame including a control section for controlling the electric element, the frame holding the lens;
a conductive wire including an elongated conductor surface that extends along and faces the edge portion, the conductive wire being connected to the control section; and
a conductive piece extending along and facing the edge portion, the conductive piece being in contact with the electrode and the conductor surface.

2. The eyewear according to claim 1 , wherein:
the edge portion is provided with a plurality of the electrodes; and
the eyewear includes a plurality of the conductive wires insulated from each other, and a plurality of the conductive pieces insulated from each other, and
wherein the plurality of conductive pieces are in contact with the plurality of electrodes different from each other and a plurality of the conductor surfaces different from each other, respectively.

3. The eyewear according to claim 2 , wherein:
the plurality of conductive wires are disposed in one cable.

4. The eyewear according to claim 2 , wherein:
the lens includes a first lens and a second lens;
the plurality of conductive wires include a first conductive wire and a second conductive wire each including two conductor surfaces of the plurality of conductor surfaces; and
the plurality of conductive pieces include a first conductive piece, a second conductive piece, a third conductive piece and a fourth conductive piece, and
wherein the first conductive piece is in contact with a first electrode of the plurality of electrodes disposed at the edge portion of the first lens and with a first conductor surface of the plurality of conductor surfaces included in the first conductive wire;
wherein the second conductive piece is in contact with a first electrode of the plurality of electrodes disposed at the edge portion of the second lens and with a second conductor surface of the plurality of conductor surfaces included in the first conductive wire;
wherein the third conductive piece is in contact with a second electrode of the plurality of electrodes disposed at the edge portion of the first lens and with a first conductor surface of the plurality of conductor surfaces included in the second conductive wire; and
wherein the fourth conductive piece is in contact with a second electrode of the plurality of electrodes disposed at the edge portion of the second lens and with a second conductor surface of the plurality of conductor surfaces included in the second conductive wire.

5. The eyewear according to claim 1 , wherein:
the lens includes a plurality of the electric elements.

6. The eyewear according to claim 1 , wherein:
the conductive piece has smaller Young's modulus than the lens.

7. The eyewear according to claim 1 , wherein:
in a direction along the edge portion, the conductive piece is longer than the electrode and shorter than the elongated conductor surface.

8. The eyewear according to claim 7 , wherein:
in the direction along the edge portion, a length “L 2 ” of the conductive piece is 1 to 2.5 times a length “L 1 ” of the electrode.

9. The eyewear according to claim 7 , wherein:
in the direction along the edge portion, the length “L 1 ” of the electrode, the length “L 2 ” of the conductive piece, a length “L 3 ” of the elongated conductor surface and a variation width “L 4 ” of a position of the electrode satisfy formulas 1 and 2 below:
L 2=2.5 L 1  (Formula 1)

L 3= L 2+ L 4  (Formula 2).

10. The eyewear according to claim 9 , wherein:
the length L 1 is 0.5 mm or more and 3 mm or less, the length L 2 is 0.5 mm or more and 7.5 mm or less, the length L 3 is 5.5 mm or more and 18.5 mm or less, and the length L 4 is 5 mm or more and 11 mm or less.

11. The eyewear according to claim 10 , wherein:
the length L 1 is 1.5 mm or more and 2.5 mm or less, the length L 2 is 1.5 mm or more and 6.25 mm or less, the length L 3 is 10.5 mm or more and 17.25 mm or less, and the length L 4 is 9 mm or more and 11 mm or less.
