Technologies for power optimization of light sources include an imaging device to generate a captured image of a subject. The imaging device analyzes the captured image to determine, in the captured image, a location of the subject's eye relative to the imaging device, an iris-pupil contrast of the subject's eye, and a glint intensity of glints present on the subject's eye. The imaging device determines, for each of a plurality of light sources, an illumination efficiency based on a distance between the camera and the subject's eye, a distance between the light source and the subject's eye, an incidence angle of the light source relative to the subject's eye, and a power profile of the light source. The imaging device determines an amount of power to supply to each light source to reduce a total cumulative power supplied to the light sources based on one or more power constraints. |
