3 Independent Claims

  • 1. A system configured to provide light therapy to a subject as the subject sleeps, the system comprising: one or more lighting modules configured to provide visible light to the eyes of the subject, one or more sensors configured to generate one or more output signals that convey information about the current sleep stage of the subject; and a processor configured to control the one or more lighting modules such that the one or more lighting modules provide visible light to the eyes of the subject, wherein the processor causes the intensity of the visible light provided to the eyes of the subject by the one or more lighting modules to vary based on the one or more output signals that convey information about the current sleep stage of the subject, wherein the processor controls the one or more lighting modules such that the one or more lighting modules provide visible light at (i) a first intensity if the one or more output signals indicate that the subject is experiencing REM sleep, and (ii) a second intensity if the one or more output signals indicate that the subject is experiencing non-REM deep sleep, and wherein the first intensity is less than the second intensity.

  • 5. A method of providing light therapy to a subject as the subject sleeps, the method comprising: providing visible light to the eyes of the subject; determining the current sleep stage of the subject; and adjusting the intensity of the visible light directed to the eyes of the subject based on the current sleep stage of the subject, wherein adjusting the intensity of the visible light directed to the eyes of the subject based on the current sleep stage of the subject comprises (i) adjusting the intensity of the visible light to a first intensity if the subject is experiencing REM sleep, and (ii) adjusting the intensity of the visible light to a second intensity if the subject is experiencing non-REM deep sleep, and wherein the first intensity is less than the second intensity.

  • 9. A system configured to provide light therapy to a subject as the subject sleeps, the system comprising: means for providing visible light to the eyes of the subject; means for determining the current sleep stage of the subject; and means for adjusting the intensity of the visible light directed to the eyes of the subject based on the current sleep stage of the subject, wherein the means for adjusting the intensity of the visible light directed to the eyes of the subject based on the current sleep stage of the subject comprises (i) means for adjusting the intensity of the visible light to a first intensity if the subject is experiencing REM sleep, and (ii) means for adjusting the intensity of the visible light to a second intensity if the subject is experiencing non-REM deep sleep, and wherein the first intensity is less than the second intensity.
