the first electrode is provided on an elongated section of one of the nose pads, and the second electrode is provided on an elongated section of the other of the nose pads, and

the elongated sections of each of the nose pads elongate downward such that the first electrode and the second electrode can be brought in contact to the skin below the eyes of a human wearing the eyewear.

4. The eyewear according to claim 1 , further comprising:

a first electric wire, a second electric wire and a third electric wire respectively electrically connected to the first electrode, the second electrode and the third electrode and buried in the frame, wherein

the first electric wire is buried in the right side of the frame,

the second electric wire is buried in the left side of the frame, and

the third electric wire is buried in the both sides of the frame.

5. The eyewear according to claim 1 , further comprising:

a first electric wire, a second electric wire and a third electric wire respectively electrically connected to the first electrode, the second electrode and the third electrode and buried in the frame; and

a ground electrode provided on a surface of either of a right ear pad or a left ear pad of the frame;

wherein the first electric wire is buried in the right side of the frame, the second electric wire is buried in the left side of the frame, and the third electric wire is buried in one of the right ear pad or the left ear pad of the frame in which no ground electrode is provided.

6. The eyewear according to claim 1 , further comprising:

a first electric wire, a second electric wire and a third electric wire respectively electrically connected to the first electrode, the second electrode and the third electrode and buried in the frame;

wherein the first electric wire is buried in the right side of the frame, the second electric wire is buried in the left side of the frame, and the frame includes a right hinge and a left hinge both made of an electrically conductive material;

wherein the right hinge includes a first hinge and a second hinge that is provided below the first hinge and is distanced apart from the first hinge, and the left hinge includes a third hinge and a fourth hinge that is provided below the third hinge and is distanced apart from the third hinge; and

wherein at least one of the first hinge and the third hinge is in contact with the third electric wire, the second hinge is in contact with the first electric wire, and the fourth hinge is in contact with the second electric wire.

7. The eyewear according to claim 1 , wherein

the frame includes a rim, and

the bridge is provided on an upper end of the rim.

8. The eyewear according to claim 1 , wherein

the third electrode is provided above the center of the bridge.

9. The eyewear according to claim 1 , wherein

the bridge includes an elongated section that elongates upward, and the elongated section is provided with the third electrode.

10. The eyewear according to claim 9 , further comprising:

a movable section provided between the elongated section and the bridge, the movable section moving the elongated section up and down.

11. The eyewear according to claim 1 , wherein

the computer is further programmed to check whether V1 and V2 satisfy pre-registered conditions including a first condition that V1+V2 indicates a negative value and V1−V2 equals substantially zero, a second condition that V1+V2 indicates a positive value and V1−V2 equals substantially zero, a third condition that V1+V2 equals substantially zero and V1−V2 indicates a negative value, and a fourth condition that V1+V2 equals substantially zero and V1−V2 indicates a positive value and to determine whether a human wearing the eyewear is looking up, down, to the right, or to the left on the basis of whether V1 and V2 satisfy the first condition, the second condition, the third condition, or the fourth condition.

12. A system comprising:

an eyewear including:

a frame,

a pair of nose pads,

a first electrode and a second electrode respectively provided on the surface of the pair of nose pads, the first electrode and the second electrode operable to detect eye potential, and

a third electrode provided equidistant from the first electrode and the second electrode on the surface of a bridge of the frame and operable to detect eye potential; and

a computer programmed to determine whether a human wearing the eyewear has blinked on the basis of whether both a potential V1 of the first electrode relative to the third electrode and a potential V2 of the second electrode relative to the third electrode indicate a sequence of pulses of approximately the same level within a certain period of time.

13. The system according to claim 11 , wherein

the computer is further programmed to check whether V1 and V2 satisfy pre-registered conditions including a first condition that V1+V2 indicates a negative value and V1−V2 equals substantially zero, a second condition that V1+V2 indicates a positive value and V1−V2 equals substantially zero, a third condition that V1+V2 equals substantially zero and V1−V2 indicates a negative value, and a fourth condition that V1+V2 equals substantially zero and V1−V2 indicates a positive value and to determine whether a human wearing the eyewear is looking up, down, to the right, or to the left on the basis of whether V1 and V2 satisfy the first condition, the second condition, the third condition, or the fourth condition.
