如果眼睛不与消色差系统的光轴共轴，那么校正人眼聚焦色差将导致我们所不期望的色视差。用几何光学方法可以证明视差量大约与眼睛的不共轴量成正比，其比例常数与眼睛的色差相同。饮用两种市场上可得到的消色差透镜，通过色差试验证实了此推测。基于这些结果，可以计算出，该消色差透镜给眼睛的复色调制传递函数提供的改进量，将由于透镜和眼睛之间的大约0．4mm的不共轴性抵消。对比灵敏度的心理物理实验已证实了我什1的推测：不关轴量的进一步增大特严重降低已消色差眼睛的成像质量。
If the eye is not coaxial with the optical axis of the achromatic system, then correcting the human eye for focusing the chromatic aberration will result in an unwanted color parallax. Using geometrical optics, it can be shown that the amount of parallax is approximately proportional to the non-coaxial amount of the eye, with the same proportionality constant as that of the eye. Drinking two types of achromatic lenses available on the market, this speculation was confirmed by a chromatic aberration test. Based on these results, it can be calculated that the amount of improvement provided by the achromatic lens to the bicolor modulation transfer function of the eye will be offset by the non-coaxiality of about 0.4 mm between the lens and the eye. Contrast-sensitivity psychophysical experiments have confirmed myths to speculate that a further increase in uncorrected axial volume severely reduces the imaging quality of anchromatic eyes.
