Abstract:
1. A sleep mask configured to provide light therapy to a subject to impact circadian rhythms and/or light deficient disorders of the subject, the sleep mask comprising: a shield configured to cover the eyes of a subject wearing the sleep mask such that the shield blocks ambient radiation from the eyes of the subject, the shield having one or more apertures configured to allow ambient light to reach the eyes of the subject; one or more radiation sources configured to emit radiation that provides light therapy to the subject, emitting radiation that provides light therapy including emitting radiation having first wavelengths during a first portion of the light therapy and emitting radiation having second wavelengths during a second portion of the light therapy, the one or more radiation sources being carried by the shield such that radiation emitted by the one or more radiation sources is directed to the eyes of the subject; and one or more filters disposed in the one or more apertures in the shield, the one or more filters being configured: (i) to block ambient radiation at wavelengths that, if allowed to reach the eyes of the subject, would interfere with the light therapy provided to the subject by the radiation emitted by the one or more radiation sources, and (ii) to enable ambient radiation to pass through the one or more apertures at wavelengths that do not interfere with the light therapy provided to the subject by the radiation emitted by the one or more radiation sources,
