References(9) When different images are presented separately to both eyes, an alternation of two views often occurs. Especially, differences in the color of two view fields can also cause rivalry, which is known as “ Color Rivalry”. In this research, we measured the dominant wavelength limits Δλd of binocular color fusion on peripheral visions of retinal eccentricity of 0(central vision), 3, 6 and 9 degrees on horizontal meridian respectively, by using a three-dimensional display to present dichoptic stimuli to the left and right eye separately. The dominant wavelength range of the stimuli was from 450 to 650 nm. The size of stimulus was 2° arc of visual angle and the luminance was set 15cd/m2. The results show that the binocular color fusion ceases when the color difference introduced between the left and right eyes exceeds a certain threshold value.The results also reveal that color fusion occurs more difficult on central visual field than on peripheral visual field and the color fusion limit Δλd becomes larger with the increase of the retinal eccentricity.
