METHOD & SYSTEM FOR TRACKING THE WEARABLE LIFE OF AN OPHTHALMIC PRODUCT
First Claim
1. A method for tracking the wearable life of an ophthalmic product, said method comprising the steps of:
- providing said ophthalmic product with at least one data carrier for carrying data related to said ophthalmic product, said data carrier having a first device operable in a magnetic and/or electrical mode;
providing an activation signal from an external means;
activating said first device with said activation signal to cause said first device to emit the data in response to said activating signal;
recording the time the first device is interrogated;
processing said received data to determine the wearable life of said ophthalmic product based on the lapsed time.

Abstract
A method for tracking the wearable life of an ophthalmic product, the method comprising the steps of: providing the ophthalmic product with at least one data carrier for carrying data related to the ophthalmic product, the data carrier having a first device operable in a magnetic and/or electrical mode; providing an activation signal from an external means; activating the first device with the activation signal to cause the first device to emit the data in response to the activating signal; recording the time the first device is interrogated, processing the received data to determine the wearable life of the ophthalmic product based on the lapsed time.

8. A system for tracking the wearable life of an ophthalmic product, the system comprising:
-
said ophthalmic product having an a data carrier for carrying data related to said ophthalmic product, said data including temporal data, said data carrier having a first device operable in a magnetic and/or electrical mode to emit said data and temporal data in response to activation by an activating signal applied by an external means;
said external means having receiving means for receiving said emitted data, counter means for recording the time of activation, and logic means for processing said received data to determine lapsed time between said temporal data and time of activation, wherein the wearable life of an ophthalmic product is based on the lapsed time. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A system for automatically tracking the wearable life of an ophthalmic product, the system comprising:
-
said ophthalmic product having an data carrier for carrying expiration data related to said ophthalmic product, said data carrier being operable in a magnetic and/or electrical mode;
a reader for interrogating said data carrier to acquire said expiration data;
a clock for tracking time;
a processor for determining wearable life of said ophthalmic product based on the clock time and the expiration data, and providing advisory signals based on said determination; and
at least one output means for outputting said advisory signals.
