Psychophysical experiments, with a new paradigm but in broad conformity with classical results on glare, were used to estimate the scattering in the eye. Combining the data with those from a companion experiment [J. Opt. Soc. Am. A 12, 1411-1416 (1995)] using objective double-pass measurements of the retinal image in the same subjects permitted a synthesis of the complete point-spread function. Results were obtained on two young subjects and one older one with more prominent scatter but normal visual acuity. This permitted the derivation of performance parameters of the eyes, such as the Strehl ratio and cumulative light functions. When the scattering was more prominent, we were able to characterize performance losses that manifested themselves in changes in absolute and contrast detection thresholds.
采用一种新的范式但大体上符合关于眩光的经典结果的心理物理学实验，来估计眼睛中的散射。将这些数据与来自一个配套实验[《美国光学学会志A》12, 1411 - 1416 (1995)]的数据相结合，该配套实验对同一受试者的视网膜图像进行了客观的双程测量，从而实现了完整点扩散函数的合成。在两名年轻受试者和一名散射更显著但视力正常的年长受试者身上获得了结果。这使得能够推导出眼睛的性能参数，如斯特列尔比和累积光函数。当散射更显著时，我们能够表征在绝对检测阈值和对比度检测阈值变化中表现出来的性能损失。
