Abstract：
Since the COVID-19 pandemic started, remote work and education and digital display use have become more prevalent. However, compared with printed material, digital displays cause more eye fatigue and may decrease task performance. For instance, the reflections on the monitor can cause discomfort or distraction, particularly when glare monitors are used with black backgrounds.
This study simultaneously uses electroencephalography (EEG) and an eye-tracker to measure the possible negative effects of using a glare monitor on the illegibility of sentences.
The experiment results showed no difference in reading time and subjective illegibility rating between glare and non-glare monitors. However, with glare monitors, eye fixation when reading lasted longer. Further, EEG beta (15-20 Hz) power variations suggested that the participants were less engaged in the reading task when a glare monitor was used with a black background.
These results indicate that the negative effects of using a glare monitor are subtle but certainly present. They also show that physiological measures such as EEG and eye tracking can assess the subtle effects in an objective manner, even if behavioral measures such as subjective illegibility ratings or reading time may not show the differences.

摘要：
■自从COVID-19大流行开始以来，远程工作和教育以及数字显示的使用变得越来越普遍。然而,与印刷材料相比，数字显示器会导致更多的眼睛疲劳，并可能降低任务性能。例如,监视器上的反射会导致不适或分心，特别是当眩光监视器与黑色背景一起使用时。
■这项研究同时使用脑电图（EEG）和眼睛跟踪器来测量使用眩光监视器对句子难以辨认的可能负面影响。
■实验结果表明，眩光和非眩光监视器之间的阅读时间和主观难以辨认等级没有差异。然而,有眩光监视器，当阅读持续更长时间时，眼睛的固定。Further,EEGβ（15-20Hz）功率变化表明，当使用黑色背景的眩光监视器时，参与者对阅读任务的参与度较低。
■这些结果表明，使用眩光监视器的负面影响是微妙的，但肯定存在。他们还表明，脑电图和眼动追踪等生理措施可以客观地评估微妙的影响，即使行为测量，如主观难以辨认等级或阅读时间可能不会显示差异。
