不舒适眩光度量通常考虑不舒适眩光-饱和度和对比度的两种效应中的至少一种。前者发生在视野中有过亮的眩光源时，而后者发生在眩光源和眼睛适应水平之间有高亮度比时。我们假设，对比效应可能在低光环境中占主导地位，比如在开放式办公室中常见的场景。因此，我们在受控实验室条件下设计并实施了一项用户研究，共有63名参与者，共252个场景，以调查在低适应水平的昏暗日光办公室环境中的不适眩光评估。 我们的初步发现支持了我们的假设，即对比度驱动的指标比对比度效应占主导地位的低适应水平下的混合指标更可靠地预测眩光反应，这突出了在低亮度条件下改进眩光指标的必要性。

Discomfort glare metrics typically consider at least one of the two effects of discomfort glare - saturation and contrast - in their equation. The former occurs when there is an excessively bright glare source in the field of view, while the latter occurs when there is a high luminance ratio between the glare source and the adaptation level of the eye. We hypothesize that the contrast effect may dominate in low-light scenarios such as those commonly found in open-plan offices. Thus, we designed and carried out a user study in controlled laboratory conditions with 63 participants with a total of 252 scenes to investigate discomfort glare evaluations in dim daylight office environments with low adaptation levels. Our preliminary findings support our hypothesis that contrast-driven metrics predict glare responses in a more reliable way than hybrid metrics at low adaptation levels where the contrast effect dominates, which underlines the need for refining glare metrics in low brightness conditions.
