An array of stimulus characteristics, such as spatial frequency content, contrast, color, and size, as well as higher-level control aspects, such as cognitive demand, instruction set, and volitional effort, may influence the steady-state accommodative response. Several experiments are reviewed which demonstrate clearly the remarkable robustness of accommodation to marked variations in these parameters. The retinal luminance gradient appears to be the primary determinant of overall response accuracy. These findings are of theoretical interest in understanding basic aspects of accommodative control, as well as being of practical importance. They suggest that the accommodative response remains relatively stable and accurate despite dynamic changes in retinal-image quality which occur under experimental and clinical, as well as more naturalistic, viewing conditions.
一系列刺激特征，如空间频率成分、对比度、颜色和大小，以及更高层次的控制因素，如认知需求、指令集和意志努力，可能会影响稳态调节反应。本文回顾了几个实验，这些实验清楚地证明了调节对这些参数显著变化的显著鲁棒性。视网膜亮度梯度似乎是整体反应准确性的主要决定因素。这些发现对于理解调节控制的基本方面具有理论意义，同时也具有实际重要性。它们表明，尽管在实验、临床以及更自然的观看条件下视网膜图像质量会发生动态变化，但调节反应仍保持相对稳定和准确。
