en The Effect of Computer Vision Syndrome on Sleep Quality in Users of Digital Displays: A Systematic Review Occupational Health Review Article <div style="text-align: justify;">Background: The increased use of digital devices has led to a rise in computer vision syndrome (CVS), particularly with remote work and online learning. Prolonged screen use also negatively impacts sleep quality. This paper aims to review existing research on the association between CVS and sleep quality in digital screen users. Material and Method: The study conducted a literature search across various databases using specified terms to find articles on the association between computer vision syndrome (CVS) and sleep quality among digital device users. The search was limited to articles published between 1900 and 2023 and followed the PRISMA guidelines for systematic reviews. Scopus, PubMed, Web of Science, and Google Scholar databases were searched for relevant articles. The inclusion criteria involved original research concurrently examining sleep quality and CVS, published in English or Persian language scientific journals. Results: The eligibility of the entire texts of 52 articles was assessed, resulting in 17 cross-sectional studies that met the inclusion criteria for this review. A significant correlation exists between eye discomfort and poor sleep quality (p<0.05), with individuals experiencing CVS frequently reporting disrupted sleep. Moreover, reduced sleep duration is significantly associated with the severity of eye problems (p= 0.001). Furthermore, the time spent using digital screens is also related to CVS and sleep quality. Conclusions: Excessive electronic device use has caused an increase in Computer Vision Syndrome (CVS) and worsened sleep quality due to prolonged screen time and exposure to blue light. To mitigate these issues, limiting screen time and using protective measures to reduce blue light exposure is crucial, as they can affect cognitive and physical performance. </div> Vision Disorders,Digital Screens,Sleep Quality,Systematic Review, 278 288 http://johe.rums.ac.ir/browse.php?a_code=A-10-465-3&slc_lang=en&sid=1 Hossein Abbaslou asalehi529@sbmu.ac.ir 22400319475328460010683 22400319475328460010683 No M.Sc. in Occupational Health Engineering, Dept. of Occupational Health Engineering, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran.
