Available theoretical and experimental data on the dependence of the subjective refraction of the eye on spherical aberration and pupil size are reviewed and additional experimental results are presented. Under photopic conditions, refraction varies little (similar to 0.3 DS) with pupil diameter, even when substantial amounts of spherical aberration are present (similar to 1.0 DS). It is argued that this result may be attributed to the insensitivity of optimal focus to spherical aberration at the spatial frequencies involved in photopic refraction, to the Stiles-Crawford effect and to the influence of aberrations other than primary spherical aberration in the outer zones of the pupil. The signficance of these findings is indicated in relation to possible discrepancies between the results of objective and subjective refractions when large pupils are in use.
本文回顾了关于眼睛主观验光与球差和瞳孔大小相关性的现有理论和实验数据，并给出了额外的实验结果。在明视条件下，即使存在大量球差（约1.0DS），屈光也随瞳孔直径变化很小（约0.3DS）。有人认为，这一结果可能归因于明视验光所涉及空间频率下最佳焦点对球差不敏感、史氏-克劳福德效应以及瞳孔外周区域除初级球差外其他像差的影响。这些发现的意义在于指出了使用大瞳孔时客观验光与主观验光结果可能存在差异的情况。
