SYSTEM FOR PROVIDING LIGHT THERAPY TO A SUBJECT USING TWO OR MORE WAVELENGTH BANDS OF ELECTROMAGNETIC RADIATION

摘要

Light therapy is provided to a subject through a sleep mask. The sleep mask is configured to deliver electromagnetic radiation to the closed eyelids of the subject within two separate wavelength bands. The first wavelength band is therapeutically impactful in adjusting the sleep cycle of the subject. The second wavelength band preconditions the subject for delivery of the electromagnetic radiation in the first wavelength band, maintains the apparent brightness of the electromagnetic radiation throughout therapy, enables cooling within the sleep mask, enhances the power efficiency of the sleep mask, and/or provides other benefits. The first wavelength band and the second wavelength band are selected based on attenuation of electromagnetic radiation by the eyelid of the subject.
