The profession of optometry has been very successful in providing optical corrections for spherocylindrical refractive errors. In this paper, I examine one attempt to improve retinal image quality beyond that afforded by a standard refractive correction. Ocular chromatic aberration is one of the factors that prevent retinal image quality from reaching the upper limit set by the wave nature of light. It can be subdivided into three primary aberrations (wavelength-dependent differences in imaging plane, image position, and image size). We have been able to measure all three of these using psychophysical techniques. Although attempts to provide an optical correction for wavelength-dependent refractive errors have been optically successful, they have failed to improve vision. Several possible explanations are given for this failure.
验光专业在为球柱面屈光不正提供光学矫正方面非常成功。在本文中，我研究了一种超越标准屈光矫正所提供的效果来改善视网膜图像质量的尝试。眼色差是阻碍视网膜图像质量达到由光的波动性质所设定的上限的因素之一。它可细分为三种主要像差（成像平面、图像位置和图像大小的波长依赖性差异）。我们已经能够使用心理物理学技术测量所有这三种像差。尽管为波长依赖性屈光不正提供光学矫正的尝试在光学上取得了成功，但它们未能改善视力。针对这种失败给出了几种可能的解释。
