Optical device characterization
First Claim
1. A method for determining the orientation of an optical device, said optical device having an anterior surface and a posterior surface, said method having the steps of:
- providing said optical device with uniquely identifiable data carrier means for carrying data related to said optical device, said data carrier means operable in at least one of an electrical mode and a magnetic mode;
said data carrier being deposited on said posterior surface and/or said anterior surface;
providing an activation signal from an external means;
activating said data carrier means with said activation signal to cause said data carrier means to emit a data signal in response to said activating signal;
processing said emitted data signal to determine said characteristics the emitted data signal;
whereby said data signal emitted by said data carrier means on said anterior surface is distinguishable from said data signal emitted by said data carrier means on said posterior surface.

Abstract
A method and system for determining the orientation of an optical device, the optical device having data carrier means for carrying data related to the optical device, the data carrier having data carrier means operable in at least one of an electrical mode and a magnetic mode; the data carrier means being associated with an optical device by at least at least one of the group of depositing on or printing on a posterior surface or anterior surface of the optical device, including the data carrier with the optical device material, wherein data carrier means emits a data signal periodically or in response to a external signal from an external means.
