ASSOCIATION OF DIGITAL VISION SYNDROME AND PROLONGED USE OF DIGITAL SCREEN FOR ONLINE STUDY DURING COVID-19 PANDEMIC AMONG THE POSTGRADUATE NURSING STUDENTS: A CROSS-SECTIONAL STUDY

Introduction: Digital eye strain is the physical discomfort felt after two or more hours in front of digital screen and is associated with close to mid-range distance of digital screen including computers and other electronic displays e.g smart phone, tablets or e-book readers. Objectives: The objective of this study is to assess the association of digital vision syndrome and prolonged use of Digital Screen among post graduate nursing students. Methodology: This Cross-sectional descriptive study was conducted at Post graduate college of nursing Lahore. Data analysis is the most important part of research to depict the real picture of information. Data analysis is the process of systematically applying statistical and /or logical techniques to describe and illustrate, condense and recap, and evaluate the data. Results: The data was collected from 96 students. The overall mean (SD) global PSQI was 6.49 (2.75). The mean (SD) score for subjective sleep quality was 0.92 (0.69); sleep latency, 1.65 (1.12); sleep duration, 1.57 (0.67); habitual sleep deficiency, 0.63(0.45); sleep disturbance, 1.04 (0.4); use of sleep medication, 0.12(0.03); daytime dysfunction, 0.58 (0.29). Table 4 gives a summary of the global PSQI and score on the individual component with years of digital device use and duration of digital device use per day. Conclusion: It is concluded that the students attending online classes are more prone to development of smartphone vision syndrome. This study had shown association between DVS and the risk factors associated with it: duration of exposure, distance from the screen and size of screen used
