Determinants of Computer Vision Syndrome (CVS) Incidence: A Case Study on Lecturers during Online Learning

Abstract

Computer screen exposure during online learning has increased the incidence of Computer Vision Syndrome (CVS). The study was conducted to analyze the determinants of CVS in lecturers during online learning. A case-control study design was conducted on 60 people consisting of 30 people each in the case and control groups. A questionnaire with a Google form was used for data collection. Data analysis was carried out univariately, bivariately and multivariately. There were 5 variables that were proven to be significant as risk factors for CVS, namely: 1) length of work with computers (OR = 18.693; 95% CI = 1.487 - 234.955); 2) length of continuous computer use (OR = 54.281; 95% CI = 2.523 - 1167.92); 3) length of rest after using a computer (OR = 31.060; 95% CI = 1.884 - 512.062); 4) viewing distance to the monitor (OR = 34.640; 95% CI = 2.263 – 530.240); and 5) the position of the top of the monitor to the horizontal eye height (OR = 17.555; 95% CI = 1.778 -173.296). These five risk factors together will provide an 83% chance of experiencing CVS. The conclusion of the study is that exposure to computer monitors experienced by lecturers during online learning will increase the risk of CVS.
