Abstract：
Background/Objectives: Modern life is inconceivable without visual display terminal (VDT) work, including smartphones, computers, and games for both children and adults. VDT work under air conditioning and low humidity poses a high risk of dry eye and digital eye strain. Methods: Thirty-one participants were randomly divided into two groups using a desktop humidifier with photocatalytic technology, namely the \"with mist\" (humidifier) group and \"without mist\" (control) group. Participants performed VDT tasks using the humidifier with or without mist for 1 h. Ocular subjective symptoms and objective tear film parameters were assessed before, immediately after, and 1.5 h after the VDT task with or without mist. (Registry ID: UMIN000054379) Results: Ocular symptom scores improved significantly in the humidifier group immediately after the VDT task and up to 1.5 h later compared to before the task (p < 0.001, =0.006, respectively). Immediately after the VDT task, tear meniscus height was significantly higher and non-invasive breakup time was significantly longer in the humidifier group than in the control group (p < 0.001, =0.040, respectively). Plugging of the meibomian gland orifices was significantly reduced only in the humidifier group immediately after the VDT task compared to before the VDT task and remained significantly reduced up to 1.5 h later (p = 0.004, 0.016, respectively). Conclusions: The use of the photocatalytic desktop humidifier during VDT task resulted in significant improvements in the tear film parameters and subjective symptoms. The photocatalytic desktop humidifier could be effective in alleviating dry eye and eye strain in computer users in a modern office environment.
摘要：
背景/目标：没有视觉显示终端（VDT）工作，现代生活是不可想象的，包括智能手机,电脑,和游戏为儿童和成人。VDT在空调和低湿度下工作会带来干眼和数字眼疲劳的高风险。方法:将31名参与者随机分为两组,使用带光催化技术的台式加湿器,即\"有雾\"(加湿器)组和\"无雾\"(对照)组。参与者使用有或没有雾的加湿器执行VDT任务1小时。之前评估眼部主观症状和客观泪膜参数，紧接着,在有或没有雾的VDT任务后1.5小时。(登记号:UMIN000054379)结果:与任务前相比,在VDT任务后即刻和至多1.5小时后,加湿器组中的眼部症状评分显著改善(分别为p<0.001,=0.006)。在VDT任务之后,与对照组相比，加湿器组的泪液半月板高度明显更高，无创破裂时间明显更长（分别为p<0.001，=0.040）。与VDT任务前相比，仅在VDT任务后立即在加湿器组中，睑板腺孔的堵塞显着减少，并且在1.5小时后仍保持显着减少（分别为p=0.004、0.016）。结论：在VDT任务期间使用光催化桌面加湿器可显著改善泪膜参数和主观症状。光催化台式加湿器可以有效缓解现代办公环境中计算机用户的干眼和眼睛疲劳。
