Many model eyes have been proposed; they differ in optical characteristics and therefore have different aberrations and image quality. In predicting the visual performance of the eye, we are most concerned with the central foveal vision. Spherical aberration is the only on-axis monochromatic aberration and can be used as a criterion to assess the degree of resemblance of eye models to the human eye. We reviewed and compiled experimental values of the spherical aberration of the eye, calculated the spherical aberration of several different categories of model eyes and compared the calculated results to the experimental data. Results show an over-estimation of spherical aberration by all models, the finite schematic eyes predicting values of spherical aberration closest to the experimental data. Current model eyes do not predict the average experimental values of the spherical aberration of the eye. A new model eye satisfying this assessment criterion is required for investigations of the visual performance of the eye.
人们已经提出了许多模型眼；它们在光学特性上有所不同，因此具有不同的像差和图像质量。在预测眼睛的视觉性能时，我们最关注的是中央凹视力。球差是唯一的轴上单色像差，可作为评估眼模型与人类眼睛相似程度的标准。我们回顾并整理了眼睛球差的实验值，计算了几种不同类别的模型眼的球差，并将计算结果与实验数据进行了比较。结果表明，所有模型都高估了球差，有限示意图眼预测的球差值最接近实验数据。当前的模型眼无法预测眼睛球差的平均实验值。研究眼睛的视觉性能需要一个满足此评估标准的新模型眼。
