L’objectif de cette étude était d’évaluer les symptômes de la vision par ordinateur et l’ergonomie visuelle dans des environnements de travail distants et hybrides pendant la pandémie de COVID-19, en mettant l’accent sur la relation entre l’œil et l’écran.

BACKGROUND: The coronavirus 2019 (COVID-19) pandemic has brought about change in the work environment, increasing remote and hybrid mode of work, presenting a compelling need to study visual ergonomics in this new work environment. OBJECTIVE: To assess computer vision symptoms and visual ergonomics in remote and hybrid work settings during the COVID-19 pandemic with a focus on eye to screen relationship. METHODS: The computer-vision symptom scale (CVSS17) questionnaire and questions about human factors and ergonomics were included in the survey conducted in September 2021. Sixty-six working professionals (mean age 37 years±5), working from home (n = 44) or in hybrid mode (n = 22) were included in the study. Cramer’s V was used for the correlation coefficient between two categorical variables for assessing eye health in changing work environments. RESULTS: Compared to our previous study, the correlation between computer vision syndrome (CVS) symptoms is markedly higher. The population working in hybrid mode experienced eye heaviness with strain to see well (V = 0.6872, p = 0.002) and dryness in the eyes (V = 0.5912, p = 0.0179). The population working from home who are bothered by surrounding lights also report dryness in the eyes (V = 0.3846, p = 0.0005). Screen use hours are higher in work from home situations (43% work more than 9 hrs) than those in hybrid mode of work (4% work more than 9 hrs). CONCLUSION: A definite increase in CVS in most of the population working remotely or in hybrid environments is established through this study. User-friendly strategies for raising awareness of applied visual ergonomics can prevent rampant onset of CVS in the working population.
