Abstract
PURPOSE: Increased screen time has been a major concern among the students who have adopted the online curriculum amid the pandemic. The study was conducted to shed light on the changing trends of symptoms pertaining to dry eye disease and digital eyestrain due to the online curriculum and its negative implications on the ocular health of students. METHODS: A cross-sectional study was conducted among students of Manipal Academy of Higher Education who are currently following the E-learning curriculum amid the COVID-19 pandemic the participants were surveyed using a pre-validated structured questionnaire. RESULTS: The mean age of study participants was 23.33 ± 4.604 years. In total, 97.9% (321/352) of the respondents experienced at least three symptoms associated with the usage of digital devices. 88.1% of the participants were exposed to an average screen time of more than 4 hours per day. An increased number of hours of digital device usage was found to be associated with higher total symptom scores (P = 0.04). The total symptom scores were found to be considerably higher for those with continuous contact with the screen (P = 0.02). Headache (69.9%, n = 246) is the most commonly reported symptom followed by neck pain (65.3%, n = 230), tearing (44.6%, n = 157), eye pain (40.9%, n = 144), and burning sensation (40.1%, n = 141). CONCLUSION: This study highlights a tremendous increase in the prevalence of symptoms related to dry eye and digital eyestrain among students attending online classes during the COVID-19 pandemic. Eye care professionals need to be aware of this emerging public health threat and the appropriate measures for its prevention.
