The scotopic spectral luminous efficiency V'([lambda]) is based on the rod photoreceptor responsivity of the eye.
For instance, a lens with a transmission graph that peaks in the red region might not appear red because what we perceive is actually the combination of the Spectral Luminous Efficiency graph and the Lens Transmission graph.
Based in part upon work by Gibson and Tyndall at NBS in 1923, the International Commission on Illumination (CIE) defined an average spectral response for the human eye for well-illuminated conditions, which is termed the spectral luminous efficiency for photopic vision.
