The glare effect is a brightness illusion that has captured the attention of the vision community since its discovery. However, its photometrical reversal, which we refer to here as photometrical reversed glare (PRG) stimuli, remained relatively unexplored. We presented three experiments that sought to examine the perceived brightness of a target area surrounded by luminance gradients in PRG stimuli and compare them with conventional glare effect configurations. Experiment 1 measured the brightness of the central target area of PRG stimuli through an adjustment task; the results showed that the target appeared brighter than similar, comparative areas not surrounded by luminance gradients. This finding was unexpected given the recent report that PRG stimuli cause pupil dilation. Meanwhile, Experiments 2 and 3 implemented a rating task to further test the findings in Experiment 1. Again, the study found a robust brightening illusion in the target area of PRG stimuli in a wide range of target and background luminance. The results are discussed in comparison with the brightness enhancement of the glare effect.

眩光效应是一种亮度错觉，自发现以来就引起了视觉界的关注。然而，其光度反转（我们在此称为光度反转眩光（PRG）刺激）仍然相对未经探索。我们提出了三个实验，旨在检查 PRG 刺激中亮度梯度包围的目标区域的感知亮度，并将其与传统眩光效果配置进行比较。实验1通过调整任务测量PRG刺激的中心目标区域的亮度；结果表明，目标看起来比没有被亮度梯度包围的类似比较区域更亮。鉴于最近有报道称 PRG 刺激会导致瞳孔扩张，这一发现是出乎意料的。同时，实验 2 和实验 3 实施了评级任务，以进一步测试实验 1 中的结果。研究再次发现，在大范围的目标和背景亮度下，PRG 刺激的目标区域存在鲁棒的增亮错觉。将结果与眩光效应的亮度增强进行比较进行讨论。
