Abstract: Experimental data suggest that for at 2°visual field during mesopicvision contrast sensitivity of human eye to chromatic sine gratings isdifference. Most were more sensitive to the green grating than the blue andred gratings. It was found that at the range of the low spatial frequencycontrast sensitivity to chromatic sine gratings is also attenuated. It was demonstrated that range of the spatial adaptation to coloured sinegratings and position of the lowest spatial frequency channels all stayed at the0.8c/d. Bandwidth of adaptation aftereffect to chromatic gratings is alsoassymetric. It was concluded that adaptation aftereffect of chromatic gratingsis mainly associated with the white-black channels, and, also with the colorchannels.
