Fig. 2

Photon flux density (PFD) spectra of colored OLED lights and relative papillary area measured during exposure to these lights in the supplementary study. a PFD spectra of blue, green, and white lights measured at the place of the eyes of subjects lying on a bed right under the ceiling light. b Average relative pupillary area measured during exposure to the lights in seven subjects in the supplementary study. Error bars indicate the range of ± SD of relative diameters. c Estimated PFD spectra of lights reaching the retina calculated from the relative pupillary areas during exposure to the lights. d Melanopic spectral efficiency curve adjusted for human pre-receptoral filtering generated from the data in reference [13]. Vertical dashed lines in both panels indicate the position of λ max of the adjusted melanoptic spectral efficiency (490 nm). e Estimated MSPFD spectra of lights reaching the retina calculated from the relative pupillary areas during exposure to the lights
