In this research, we measured the wavelength difference limit for binocular colour vision about peripheral visual field, by using a three-dimensional display to present dichoptic stimuli to the left and right eye respectively. The wavelength range of the stimuli was selected from 450 nm to 650 nm. The size of stimulus was 2° arc of visual angle, and the brightness was set 15 cd/m2. The results show that colour fusion occurs more difficult with central visual field than peripheral visual field. More importantly, it offers the basis of important fundamental data for some important optical instruments, for example the designs of optical microscopes.
