Abstract: This experiment was undertaken by using flicker method with 5 normal vision adult experienced subjects. Four visual fields were used(20′, 2°, 7°40′,10°). Level of luminance was 30cd/m~2. Test points of wavelength wereselected in the range from 420 to 700nm. The results indicated that in all different visual fields, the V(λ) valuesare basically similar in the long wave region of the spectrum, but system-atically increased with the increment of the visual field in the short waveegion of the spectrum
