An apparatus for providing light to perform retiming of a human body clock is provided. In one embodiment, the device comprises two pairs (14) of light emitting diodes (16, 18) having an emission wavelength in the range of 450 nm to 530 nm and a frame (1) adapted to be supported on the wearer's face. Including. The frame is positioned to support two pairs of light emitting diodes, with one pair being supported near the surface of each wearer's eye. Each pair of light emitting diodes projects light output that illuminates a different area of the retina of each eye, and is spaced apart to provide a viewing zone (21) between these light emitting diodes. . |
