Abstract

An eyeglass frame for supporting an optical member having an electrooptical device and a pair of electrodes exposed in different peripheral positions, comprises a front part providing a rim for supporting the optical member, the front part including first and second front members which constitute different parts of the rim, are composed of conductive metal and are mutually insulated electrically, wherein the first front member is in contact with a first peripheral part including one of the paired electrodes of the optical member while the second front member is in contact with a second peripheral part including the other of the paired electrodes, and the eyeglass frame comprises an electric power source for applying a voltage between the first and second front members, for electric supply to the electrooptical device.

Claims

1. An eyeglass frame for supporting an optical member having an electrooptical device and a pair of electrodes exposed in different peripheral positions, comprising:

a front part providing a rim for supporting said optical member, said front part including first and second front members which constitute different parts of said rim, are composed of conductive metal and are mutually insulated electrically, wherein said first front member is in contact with a first peripheral part including one of the paired electrodes of said optical member while the second front member is in contact with a second peripheral part including the other of said paired electrodes; and

means for applying a voltage between said first and second front members, for electric supply to said electrooptical device.

2. An eyeglass frame according to claim 1, wherein said first front member constitutes the upper part of said rim, while said second front member constitutes the lower part of said rim.

3. An eyeglass frame according to claim 1, wherein said optical member includes a pair of optical parts positioned at left and right of said front part, said front part provides left and right rims for supporting said pair of optical parts, and said first and second front members constitute different parts in each of said left and right rims.

4. An eyeglass frame according to claim 1, further comprising a temple part provided at an end of said front part, said temple part including first and second temple members which are respectively connected electrically to said first and second front members, are composed of conductive metal and are mutually insulated eletrically.

5. An eyeglass frame according to claim 4, wherein said voltage applying means is adapted to apply said voltage between said first and second temple members.

6. An eyeglass comprising:

an optical member having an electrooptical device and a pair of electrodes exposed in different peripheral positions;

a front part providing a rim for supporting said optical member, said front part including first and second front members which constitute different parts of said rim, are composed of conductive metal and are mutually insulated electrically, wherein said first front member is in contact with a first peripheral part including one of the paired electrodes of said optical member while the second front member is in contact with a second peripheral part including the other of said paired electrodes; and

means for applying a voltage between said first and second front members, for electric supply to said electrooptical device.

7. An eyeglass according to claim 6, further comprising a temple part provided at an end of said front part, said temple part including first and second temple members which are respectively connected electrically to said first and second front members, are composed of conductive metal and are mutually insulated electrically.

8. An eyeglass according to claim 7, wherein said voltage applying means is adapted to apply said voltage between said first and second temple members.
