There is currently considerable debate concerning the visual impact of correcting the higher order aberrations of the eye. We describe new measurements of a large population of human eyes and compute the visual benefit of correcting higher order aberrations. We also describe the increase in contrast sensitivity when higher order aberrations are corrected with an adaptive optics system. All these results suggest that many, though not all, observers with normal vision would receive worthwhile improvements in spatial vision from customized vision correction, at least over a range of viewing distances and particularly when the pupils are large. Keratoconic patients or patients suffering from spherical aberration as a result of laser refractive surgery as it is presently performed would especially benefit. These results encourage the development of methods to correct higher order aberrations.
目前，关于矫正眼睛高阶像差的视觉影响存在相当大的争议。我们描述了对大量人眼的新测量，并计算了矫正高阶像差的视觉益处。我们还描述了使用自适应光学系统矫正高阶像差时对比敏感度的增加。所有这些结果表明，许多（尽管不是全部）视力正常的观察者通过定制视力矫正，至少在一定范围的观察距离内，尤其是当瞳孔较大时，空间视觉将得到有价值的改善。圆锥角膜患者或因目前实施的激光屈光手术而患有球差的患者将尤其受益。这些结果鼓励了矫正高阶像差方法的发展。
