The relationship between night myopia under simulated night driving conditions and the dark focus accomodation was examined. Over a range of luminance and contrast conditions typical of the night driving situation, college-age subjects accommodated to about one-half the difference between a distant simulated road sign and their individual dark focus. Subsequent laboratory and field experiments demonstrated that: (1) a negative correction equal to one-half the value of the dark focus significantly improved night visual performance as compared with their normal or full dark-focus correction, and (2) greater improvements in performance were obtained for subjects who exhibited a relatively near dark focus.
研究了模拟夜间驾驶条件下的夜间近视与暗焦点调节之间的关系。在一系列典型夜间驾驶情况的亮度和对比度条件下，大学生年龄的受试者调节至远处模拟路标与他们各自暗焦点之间差异的约一半。随后的实验室和现场实验表明：（1）与他们的正常或完全暗焦点矫正相比，等于暗焦点值一半的负矫正显著改善了夜间视觉性能，并且（2）对于表现出相对较近暗焦点的受试者，性能有更大的改善。
