Background. In this globalized and high-tech era, the computer has become an integral part of daily life. A constant use of
computer for 3 hours and more per day can cause computer vision syndrome (CVS), which is one of the leading occupational
hazards of the 21
st
century. e visual difficulties are the most common health problems associated with excessive computer use.
erefore, this study aimed to assess the prevalence and associated factors of CVS among instructors working in Ethiopian
universities. Methods. A web-based cross-sectional study was conducted among 422 university instructors in Ethiopia from
February 02 to March 24, 2021. A structured and self-administered questionnaire prepared by Google Forms was shared among
instructors through their e-mail addresses, Facebook, and Telegram accounts. Data cleanup and cross-checking were done before
analysis using SPSS version 23. A multivariable logistic regression was applied to identify factors associated with CVS using p
value <0.05 and 95% confidence interval. Results. Of the total 416 participants, about 293 (70.4%) were reported to have CVS (95%
CI: 65.9–74.5%), of which 54.6% were aged 24–33 years. Blurred vision, pain in and around the eye, and eye redness were the main
symptoms reported. Working in third-established universities (AOR � 8.44, 95% CI: 5.47–21.45), being female (AOR � 2.69, 95%
CI: 1.28–5.64), being 44 years old and above (AOR � 2.73, 95% CI: 1.31–5.70), frequently working on the computer (AOR � 5.51,
95% CI: 2.05–14.81), and sitting in bent back position (AOR � 8.10, 95% CI: 2.42–23.45) were the factors associated with computer
vision syndrome. Conclusions. In this study, nearly seven-tenths of instructors in Ethiopian universities reported having
symptoms of computer vision syndrome. Working in third-generation universities, being female, age, frequently working on the
computer, and sitting in bent back position were statistically significant predictors in computer vision syndrome. erefore,
optimizing exposure time, addressing ergonomic hazards associated with computer usage through on-the-job and off-the-job
training, and making the safety guidelines accessible for all university instructors would be critical to address the problem.
1. Background
In this globalized and hi-tech era, the computer has become
an integral part of daily life [1]. ese devices are deliberated
as the necessity of 21
st
century and being used at workplaces
and household level. ere has been a rapid increase in
computer-related health problems in the current era of
prolonged and extensive computer usage [2, 3]. A constant
use of computer for 3 hours and more per day can cause
computer vision syndrome (CVS), which is defined as a
complicated eye and vision difficulty linked to the activities
