Abstract

An adapter for a spectacle frame is disclosed which is configured for enabling the spectacle frame to operate and control electro-active lenses housed therein. In particular, the spectacle frame may allow electro-active lenses housed therein to focus and be controlled both automatically and manually with heretofore unrealized results.

Claims

1. Spectacles, comprising:

a first electro-active lens;

a second electro-active lens; and

a synchronization transmitter for coordinating operation of the second electro-active lens with the first electro-active lens.

2. The spectacles of claim 1, wherein the synchronization transmitter comprises an infrared (IR) transmitter.

3. The spectacles of claim 1, wherein the synchronization transmitter comprises a radio frequency (RF) transmitter.

4. The spectacles of claim 1, wherein the synchronization transmitter comprises a pulsed current source.

5. The spectacles of claim 1, further comprising a flexible circuit.

6. The spectacles of claim 1, wherein the synchronization transmitter comprises an ultrasonic transmitter.

7. The spectacles of claim 1, wherein the synchronization transmitter comprises a vibration transducer.

8. The spectacles of claim 1, wherein the first and second electro-active lenses are activated at substantially the same time.

9. The spectacles of claim 1, wherein optical powers of the first and second electro-active lenses are changed from a first state to a second state, respectively, at substantially the same time.

10. The spectacles of claim 1, further comprising an adapter containing a power source.

11. The spectacles of claim 10, wherein the adapter is connected to electrical leads extending from one of the first and second electro-active lenses.

12. The spectacles of claim 11, wherein the electrical leads are exposed during edging.
