Simple formulas based on reduced eyes have been developed to predict the variation in longitudinal chromatic aberration with variation in ametropia or accommodation. Two formulas were developed, one for axial ametropia and one for refractive ametropia. The latter also served as a model for accommodation. The results using the formulas are in close agreement with results obtained using raytracing through more sophisticated models. Combining the results of different methods gives the following predictions of change in chromatic difference of focus, between wavelengths of 400 and 700 nm, with change in each diopter of refractive error or accommodation: axial ametropia 0.012 to 0.017 D (0.6 to 0.9%), refractive ametropia 0.05 D (2.2 to 2.4%), and accommodation 0.04 to 0.05 D (2.1 to 2.6%). The chromatic aberration effects of correcting lenses with low dispersion are intermediate in effect and opposite in sign to the effects of corresponding degrees of axial ametropia and refractive ametropia.
基于简化眼已经开发出简单公式，以预测纵向色差随屈光不正或调节变化的情况。开发了两个公式，一个用于轴性屈光不正，一个用于屈光性屈光不正。后者也用作调节的模型。使用这些公式得到的结果与通过更复杂模型进行光线追踪得到的结果非常一致。结合不同方法的结果，得出了以下关于在400至700纳米波长之间，随着每屈光度屈光不正或调节变化，焦点色差变化的预测：轴性屈光不正为0.012至0.017 D（0.6%至0.9%），屈光性屈光不正为0.05 D（2.2%至2.4%），调节为0.04至0.05 D（2.1%至2.6%）。低色散矫正镜片的色差效应在效果上介于两者之间，且符号与相应程度的轴性屈光不正和屈光性屈光不正的效应相反。
