## Abstract

Electronic spectacles include a spectacle frame; lenses having electric elements; a control unit that generates electric signals for driving the electric elements of the lenses; electric connectors that transmit the signals from the control unit to wiring connector pads; and the electric connector have one end connected to a control unit for controlling the electric element and an another end connected to lens electrode pads. The lens has an inverted V-shaped protrusion.

## Claims

### Claim 1

Electronic spectacles in which a lens comprising an electric element is set in a spectacle frame,
the lens having an inverted V-shaped protrusion at an outer sidewall of the lens,
lens electrode pads exposed on the inverted V-shaped protrusion, the lens electrode pads applying a voltage to the electric element,
an electric connector having a first end connected to a control unit for controlling the electric element and a second end connected to the lens electrode pads.

### Claim 2 (depends on 1)

The electronic spectacles according to claim 1, wherein the second end of the electric connector is provided at the inside of a rim.

### Claim 3 (depends on 2)

The electronic spectacles according to claim 2, wherein wiring electrode pads are set on the second end of the electric connector provided at the inside of the rim.

### Claim 4 (depends on 3)

The electronic spectacles according to claim 3, wherein a rubber member is interposed between the lens electrode pads and the wiring electrode pads.

### Claim 5 (depends on 4)

The electronic spectacles according to claim 4, wherein the rubber member is a conductive rubber.

### Claim 6 (depends on 5)

The electronic spectacles according to claim 5, wherein the rubber member is an anisotropic conductive rubber.

### Claim 7 (depends on 2)

The electronic spectacles according to claim 2, wherein the lens electrode pads are in a recess provided on the inverted V-shaped protrusion.

### Claim 8 (depends on 7)

The electronic spectacles according to claim 7, wherein the recess is formed at a part of two planes which make up the inverted V-shaped protrusion.

### Claim 9 (depends on 7)

The electronic spectacles according to claim 7, wherein the recess is formed on one of two planes which constitute the inverted V-shaped protrusion.
