This brief review outlines the theory of ocular chromatic aberration and describes the three primary forms in which the aberration appears: chromatic difference of focus, chromatic difference of magnification, and chromatic difference of position. Our central theme is that all three aspects of chromatic aberration have as their common basis the chromatic dispersion of light. The magnitude of each form of the aberration is related to the others by simple linear formulas in which a key parameter is the location of the pupil relative to the nodal point of the eye. The way in which retinal image quality is affected by chromatic aberration is described and we assess the impact of the aberration on visual performance.
本简要综述概述了眼色差理论，并描述了色差出现的三种主要形式：焦色差、放大率色差和位置色差。我们的核心主题是，色差的所有这三个方面都以光的色散为共同基础。每种色差形式的大小通过简单的线性公式相互关联，其中一个关键参数是瞳孔相对于眼睛节点的位置。文中描述了色差影响视网膜图像质量的方式，并评估了色差对视觉性能的影响。
