ABSTRACT
Purpose
To evaluate dry eye (DE) and subjective visual display terminal (VDT)-related symptoms in university students who moved their classes online due to the COVID-19 pandemic.
Methods
Cross-sectional study of students who were taking online classes. In May 2020, the participants completed a Dry Eye Questionnaire (DEQ-5) and a self-report survey, which included demographics, medical history, information on the use of VDT and presence of VDT-related symptoms. Participants were classified as having mild/moderate (7–12) or severe (>12) DE symptoms based on their DEQ-5 score. The associations between severe DE symptoms and relevant factors were also evaluated.
Results
The data of 1450 eligible students were analyzed. The mean age of the participants was 21.1 (2.7) years. 42.8% of the participants had mild/moderate DE symptoms, whereas 34.7% had severe symptoms. Associated factors for severe DE were female sex (OR = 2.57, CI [1.97–3.35]), allergic disease (OR = 1.63, CI [1.24–2.13]), previous dry eye diagnosis (OR = 13.49, CI [7.10–25.63]), keratoconus (OR = 5.56, CI [1.27–24.44], contact lens use (OR = 1.77, CI [1.24–2.53]) and duration of VDT use (OR = 1.02, CI [1.01–1.05]). Prior to the pandemic, the mean reported duration of VDT use was 9.8 (4.7) hours; this increased to 15.9 (5.8) hours during the online classes (p < .001). 80.6% of the participants reported a global increase in VDT-related symptoms.
Conclusion
Students taking online classes had a high frequency of DE symptoms. They also reported a significant increase in VDT-related symptoms. DE should be considered as an emerging health problem among the young population, which is probably related to the recent changes in lifestyle.
