The present study confirms that the individual variations of the Stiles' 20 color-matching functions are physiologically well predicted by those of eye-lens and macular optical densities. The principal-component analysis of the blue colormatching functions shows the significance of the two independent spectral components, which are expected to correspond to lens and macular optical densities. The lens and macular densities for each of the Stiles' 20 observers are estimated by using their published data physiologically measured. The estimated densities well predict each of the Stiles' 20 colormatching functions. The singular-value decomposition of the estimated 20 color-matching functions gives a good estimate to the standard-deviate observer derived from the original Stiles 20 color-matching functions by using the same procedure.
