To assess digital eye strain (DES) among schoolchildren during lockdown.
An online questionnaire-based, cross-sectional study was conducted. A validated, self-administered, electronic questionnaire was circulated among students of 5-18 years of age. The duration of data collection was from May 18, 2020 to May 24, 2020. Rasch-based Computer-Vision Symptom Scale was deployed to measure the DES.
A total of 654 students (mean age: 12.02 ± 3.9 years) completed the survey. The average per day digital device exposure was 5.2 ± 2.2 h. A total of 507 (92.8%) children reported experiencing at least one asthenopic/dry eye symptom (AS/DS). The most prevalent symptoms were eye redness (69.1%) and heaviness of eyelids (79.7%). Significant positive correlation was reported between age and per day duration of digital device exposure (Pearson correlation 0.25; < 0.001). Computer vision syndrome (CVS) score for spectacle users was significantly higher ( < 0.001). CVS score was found to correlate significantly with age and duration of digital device exposure ( < 0.001).
Most of the students surveyed, experienced at least one symptom of DS or AS, indicating a need to educate them about the possible deleterious effects and help them adapt to the currently evolving education system.
评估封锁期间学童的数字视疲劳（DES）情况。
开展了一项基于在线问卷的横断面研究。向5至18岁的学生发放了一份经过验证的、可自行填写的电子问卷。数据收集时间为2020年5月18日至2020年5月24日。采用基于拉施模型的计算机视觉症状量表来测量数字视疲劳。
共有654名学生（平均年龄：12.02±3.9岁）完成了调查。每天数字设备暴露的平均时长为5.2±2.2小时。共有507名（92.8%）儿童报告至少出现一种眼疲劳/干眼症状（AS/DS）。最常见的症状是眼睛发红（69.1%）和眼睑沉重（79.7%）。年龄与每天数字设备暴露时长之间存在显著正相关（皮尔逊相关系数为0.25；P<0.001）。戴眼镜者的计算机视觉综合征（CVS）得分显著更高（P<0.001）。发现CVS得分与年龄和数字设备暴露时长显著相关（P<0.001）。
大多数接受调查的学生至少出现了一种DS或AS症状，这表明有必要对他们进行教育，让他们了解可能的有害影响，并帮助他们适应当前不断发展的教育系统。
