Abstract
The present disclosure provides a circadian rhythm correcting apparatus including a bio-illuminance measuring part configured to measure bio-illuminance of external light, a light source configured to irradiate light of a circadian wavelength band toward a retinal ganglion cell, a light source driver configured to drive the light source by supplying power to the light source, and a controller configured to control the light source driver on the basis of the bio-illuminance measured by the bio-illuminance measuring part, to correct the circadian rhythm.
