Purpose : The purpose of this study is to investigate the effect of digital devices on the tear film by investigating the use time of digital devices for university students and measuring the non-invasive tear film break-up time (NITBUT).
Methods : For 2 months from August 2022, 55 university students involved in the Chungnam area were analyzed. Tear film evaluation measured NITBUT using Cornea 550 and divided it into dry eye and normal eyes. The questionnaire examined a total of 14 questions about the subjects' general characteristics, the environment in which they used digital devices, and the subjective dry eye-related symptoms.
Results : Participants spent an average of 9.93±4.90 hours per day using digital devices.
In the group that used digital devices for more than 8 hours a day, 58.5% of cases of dry eyes were NITBUT and significantly higher than 21.4% for less than 8 hours (p=0.029). In addition, subjects who used digital devices for more than 8 hours a day reported higher eye dryness and fatigue, and the use of digital devices for more than 8 hours after adjusting for age, sex, contact lenses, refractive surgery, smoking, and sleep time increased the probability of dry eyes by 5.18 times (p=0.023). When the digital device was a smartphone, 53.8% of the NITBUT group was normal and 69.0% in the dry eye group (p>0.050).
Conclusion : University students found that when used for more than 8 hours, the NITBUT was shortened, and the probability of dry eyes increased.
