The direction of chromostereopsis observed with a natural pupil and the direction of the monocularly perceived disparity between coloured targets (F and C lines - 486 and 656 nm) have been measured in a sample of 30 subjects at 10 and 1000 lx. At both illumination levels approximately equal numbers of subjects perceived positive and negative chromostereopsis. When the ambient illumination was increased, a reversal in the direction of the chromostereopsis occurred for 16 subjects. For six of them a change from a positive to a negative chromostereopsis was observed, a pattern not reported in previous studies. In most cases at both high and low illuminance, there was an absence of perception of a monocular disparity (transverse chromatic aberration), although chromostereopsis was reported, indicating that binocular information can be obtained from sub-threshold monocular disparities. At low illuminance, the lack of correlation between the direction of chromostereopsis and transverse chromatic aberration (TCA) may indicate that there may be a supplementary binocular factor in chromostereopsis.
在30名受试者的样本中，于10勒克斯和1000勒克斯的光照条件下，测量了自然瞳孔观察到的色立体视方向以及有色目标（F和C线 - 486纳米和656纳米）之间单眼感知视差的方向。在这两种光照水平下，感知到正色立体视和负色立体视的受试者数量大致相等。当环境光照增加时，16名受试者的色立体视方向发生了反转。其中6人观察到从正色立体视变为负色立体视，这是先前研究中未报道的模式。在大多数情况下，无论高光照还是低光照，尽管报告了色立体视，但都没有单眼视差（横向色差）的感知，这表明双眼信息可以从阈下单眼视差中获得。在低光照条件下，色立体视方向与横向色差（TCA）之间缺乏相关性可能表明色立体视中可能存在一个补充性的双眼因素。
