Abstract: A method for tracking ophthalmic lens care compliance, said method comprising the steps of: including at least one sensor with said ophthalmic product for monitoring at least one ambient condition and for logging and recording at least one parameter associated said at least one ambient condition, following a predetermined event; comparing said at least one parameter to a predetermined threshold and providing an outcome, said predetermined threshold corresponding to said at least one ambient condition, and issuing an alert based on said outcome.

Abstract: A method for tracking ophthalmic lens care compliance, said method comprising the steps of: including at least one sensor with said ophthalmic product for monitoring at least one ambient condition and for logging and recording at least one reading associated said at least one ambient condition, following a predetermined event; determining whether said at least one reading exceeds at least one predetermined threshold, and issuing an alert when said at least one reading exceeds at least one predetermined threshold.

Abstract: A reminder method and system for merchandise returns or exchange within a predetermined time post-purchase.

Abstract: A method and system for enforcing a return policy by determining whether an article of merchandise has been used, or not used, within a predetermined time after the purchase of the merchandise. The system including sensor means associated with the article for recording data related to ambient conditions post-purchase, data acquisition means for receiving the recorded data, a comparator for comparing the recorded data to a predefined data set representative of acceptable data values, output means for outputting an outcome from the comparator, the outcome being indicative of whether the article has been used, or not used.

Abstract: A method and system for determining the orientation of an ophthalmic lens for assisting a user to readily determine the eye contacting surface of the ophthalmic lens prior to insertion into the eye.

Abstract: A method and system for providing the characteristics of an ophthalmic lens, the ophthalmic lens comprising a data carrier for carrying data associated with the ophthalmic lens, the data carrier having a device operable to emit data in response to activation by an electromagnetic wave activating signal applied by an external means.

Abstract: An optical device having an anterior surface and a posterior surface, 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; said data carrier means caused to emit a data signal in response to said activating signal by an external means; said emitted data signal used to determine characteristics of said optical device.

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.

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.
