Abstract

Brightness luminous-efficiency functions for point sources and for 2° and 10° fields are based on 6, 63, and 76 subjects, respectively. The function for point sources can be approximated by Judd’s 1951 modification of the CIE V(λ) function. The 2° and 10° functions differ greatly from V(λ). The two functions differ from each other only at wavelengths from 410 through 520 nm, where the differences are attributed to absorption by the macular pigment.
