Abstract
Background: Computers and other visual display devices have become essential in the present era and have led to a rise in computer-related health problems. Using computers in homes, universities and other institutions has increased output greatly but has also led to an increased risk of developing Computer vision syndrome (CVS). Objectives: To determine the prevalence and risk factors associated with computer vision syndrome among undergraduates. Methodology: A cross-sectional study was conducted among153 respondents who were selected using a multi-stage sampling technique. A pretested, structured, interviewer-administered questionnaire was used to collect data. SPSS version 23 was used to analyze the data. A Chi-square test was used to determine the relationship between CVS and associated risk factors at a P-value of <0.05. Results: The mean age of respondents was 22.4 ± 3.4 years. The prevalence of CVS in this study was 83 (54.3%). The common symptoms experienced among the respondents were headache (51, 61.4%), eye strain (48, 57.8%) and blurred vision (42, 50.6%). The risk factors significantly associated with CVS in this study were duration of computer use, hours of computer use per day, level of a computer screen and taking breaks during computer use. Conclusion: About half of the students in this study had at least one symptom of CVS. Therefore, awareness of CVS should be created by the institution during which students would be educated on CVS and its prevention.
Highlights
With the advent of modern technology, the use of computer devices and gadgets has almost become indispensable in every aspect of life.[1]
A statistically significant relationship was found between duration of computer use, hours of computer use per day, the level of the computer screen, taking breaks and the prevalence of Computer vision syndrome (CVS)
The lower mean age in this study may be because the study population is composed of university students and 83.4 % of the respondents were below 27 years whereas the study in Abuja, Nigeria was conducted among workers with 58% of them above 30 years
Summary
With the advent of modern technology, the use of computer devices and gadgets has almost become indispensable in every aspect of life.[1]. 2 In recent years, other devices have been added to computer use, these include tablets, ereaders and smartphones that are characterized, among others, by being lightweight and more portable than computers. All of these devices have a backlit screen and are referred to jointly as video display terminals (VDTs). Universities and other institutions has increased output greatly but has led to an increased risk of developing Computer vision syndrome (CVS). Objectives: To determine the prevalence and risk factors associated with computer vision syndrome among undergraduates. Awareness of CVS should be created by the institution during which students would be educated on CVS and its prevention
