USER-WEARABLE DEVICES THAT MONITOR EXPOSURE TO BLUE LIGHT AND RECOMMEND ADJUSTMENTS THERETO

摘要

Described herein are user-wearable devices that include an optical sensor, and methods for use therewith. In certain embodiments, an optical sensor of a user-wearable device (e.g., a wrist-worn device) is used to detect blue light that is incident on the optical sensor and to produce a blue light detection signal indicative thereof, and thus, indicative of the response of the user's intrinsically photosensitive Retinal Ganglion Cells (ipRGCs). In dependence on the blue light detection signal, there is a determination of a metric indicative of an amount of blue light detected by the optical sensor. The metric is compared to a corresponding threshold, and a user notification is triggered in dependence on results of the comparing, wherein the user notification informs a person wearing the user-wearable device to adjust their exposure to light.

1. A method for use by a user-wearable device including an optical sensor, the method comprising:
(a) using the optical sensor of the user-wearable device to detect blue light that is incident on the optical sensor and to produce a blue light detection signal indicative thereof; (b) determining, in dependence on the blue light detection signal, a metric indicative of an amount of blue light detected by the optical sensor; (c) comparing the metric to a corresponding threshold; and (d) triggering a user notification in dependence on results of the comparing, wherein the user notification informs a person wearing the user-wearable device to adjust their exposure to light.
