This study investigates the effects of ambient illumination and negatively polarized text color on visual fatigue, exploring the issue of visual fatigue when using visual display terminals in low-illumination environments. The research methodology utilizes an experimental design to collect data on changes in pupil accommodation and blink rate through an eye tracker. Participants completed a reading task while exposed to various text colors and ambient light conditions to evaluate visual fatigue and cognitive performance. The study's findings suggest that text color significantly affects visual fatigue, with red text causing the highest level of visual fatigue and yellow text causing the lowest level of visual fatigue. Improvements in ambient lighting reduce visual fatigue, but the degree of improvement varies depending on the text color. Additionally, cognitive performance is better when using yellow and white text but worse when using red text. Yellow text is the most effective choice for reducing visual fatigue under negative polarity. Increasing ambient lighting can also improve visual fatigue in low-illumination conditions. These findings will offer valuable guidance for designing visual terminal device interfaces, especially for low-illumination or night environments, to minimize visual fatigue and improve user experience.
本研究调查了环境光照和负偏振文本颜色对视觉疲劳的影响，探讨了在低光照环境下使用视觉显示终端时的视觉疲劳问题。研究方法采用实验设计，通过眼动仪收集瞳孔调节和眨眼频率变化的数据。参与者在接触各种文本颜色和环境光条件下完成阅读任务，以评估视觉疲劳和认知表现。研究结果表明，文本颜色显著影响视觉疲劳，红色文本导致的视觉疲劳程度最高，黄色文本导致的视觉疲劳程度最低。环境光照的改善可减轻视觉疲劳，但改善程度因文本颜色而异。此外，使用黄色和白色文本时认知表现较好，而使用红色文本时认知表现较差。在负极性下，黄色文本是减轻视觉疲劳的最有效选择。增加环境光照也可改善低光照条件下的视觉疲劳。这些发现将为设计视觉终端设备界面提供有价值的指导，特别是对于低光照或夜间环境，以尽量减少视觉疲劳并改善用户体验。
