From: Effect of the chromaticity of stimuli on night vision disturbances

Bar graph showing the mean values of the monocular and binocular visual disturbance indices (VDI) under different conditions (achromatic, red, green, and blue) for the maximum luminance of the central stimulus, Lmax (EDL values of 255) and for the maximum luminance of the blue channel, L(Bmax). Standard deviations are shown by the vertical bars.
