ASSESSMENT OF PREVALENCE OF DIGITAL EYE STRAIN AMONG DIGITAL SCREEN USERS IN SETTING OF COVID-19 PANDEMIC.
AIMS AND OBJECTIVES: To assess the impact of the increased digital device usage and its ocular surface health implications along with circadian rhythm abnormalities related to digital eye strain during COVID-19 pandemic. METHODS: A validated questionnaire was provided to all the participants and various symptoms people experienced were analyzed. Dry eye tests were performed in all the study subjects. RESULTS: A total of 256 participants were included of which 88.3% of subjects reported an increase in their screen time since the onset of pandemic. The average increase in digital device usage was calculated at about 4.4 ± 1.9 h per day. The total usage per day was found to be7.85 ± 3.63 hours. Sleep disturbances have been reported by 59.8% of participants. Typically, 93% of respondents had experienced at least one symptom related to digital device usage, and 66.4% said that the frequency and intensity of these symptoms increased since the pandemic started. Dry eye diagnosed clinically by Schirmer's test was present in 18.8 % of participants. CONCLUSION: The study highlights the increase in usage of digital devices after the onset of the COVID-19 pandemic leading to increase in digital eye strain across all age groups.
