【摘要】：目的了解大学本科生数字化阅读习惯的流行现状,探讨其对视疲劳的影响。方法采用多阶段整群抽样方法,抽取北京大学729名本科生,进行数字化阅读行为和视疲劳自述症状的问卷调查。结果在使用固定设备进行数字化阅读时,27.8%的学生平均每次阅读时间超过2 h,56.9%的学生眼睛与屏幕的距离小于50 cm;在使用移动设备时,16.5%的学生平均每次阅读时间超过60 min,47.2%的学生眼睛与屏幕的距离小于30 cm。此外,有61.3%的学生有在床上阅读的不良习惯,阅读时会经常休息眼睛的学生仅占13.3%。固定设备阅读时,不同持续时间和眼屏距离对眼酸的影响,不同眼屏距离对异物感的影响均有统计学意义(χ2值分别为11.002,7.049,7.134,P值均0.05);移动设备阅读时,不同持续时间对流泪的影响,不同眼屏距离对异物感的影响均有统计学意义(χ2值分别为14.622,7.134,P值均0.05)。结论大学生不良的数字化阅读习惯普遍存在,其对视疲劳的影响较大,对眼睛的保护应从加强护眼意识等主观方面入手。
[Abstract]:Objective to investigate the prevalence of digital reading habits of undergraduates and their effects on visual fatigue. Methods 729 undergraduates of Peking University were selected by multi-stage cluster sampling. Results the average reading time of 27.8% of the students was more than 2 hours each time when using fixed equipment to read digitally. 56.9% of the students were less than 50 cm away from the screen. When using mobile devices, 16.5% of the students read more than 60 mins and 47.2% of the students' eyes were less than 30cms. in addition, the distance between the eyes and the screen was less than 30 cm. 61.3% of the students had the bad habit of reading in bed. Only 13.3% of the students would rest their eyes while reading. The effect of different distance of eye screen on foreign body sensation was statistically significant (蠂 ~ 2 = 11.002 ~ 7.049 ~ 7.134 P = 0.05). The effects of different duration on tears and different distance of eye screen on foreign body sensation were statistically significant (蠂 ~ 2 = 14.622 卤7.134, respectively). Conclusion the bad digital reading habits of college students are common and have a great influence on visual fatigue. The protection of the eyes should start from the subjective aspects such as strengthening the consciousness of eye protection and so on.
