Abstract
A device is provided for treating a circadian rhythm disorder in a subject. The device includes a plurality of light emitting diodes (LED's), preferably blue to green; a mounting to which the LED's are connected: a material for positioning the LED's within 3 cm of the subject, with an orientation toward the subject; a portable power supply electrically connected to the LED's; and a control connected to the LED's for altering the operation of the LED's. The device is sufficiently light and compact to be comfortably worn by the subject. One or more such devices are used to deliver light to a subject's retinas, to the subject's vascular tissue, or simultaneously to both the retinas and the vascular tissue. For illumination of the retina, small chip-type LED's are integrated into the frames of eyeglasses and positioned to direct light into the eyes of the subject. For illumination of the vascular tissue, an array of lens or chip type LED's are contained in a casing that is secured against the skin of the subject. The devices can be used independently of each other, or can be used in combination for more effective and/or flexible treatment.
