Introduction:
The digitalization of society has significantly transformed the modern workplace, with over 60% of employees in developed countries using computers daily. While this shift has enhanced work efficiency, it has also introduced new challenges in occupational medicine, particularly due to the increasing prevalence of Computer Vision Syndrome (CVS). According to the American Optometric Association, CVS – also known as digital eye strain – encompasses a range of eye and vision problems caused by prolonged use of digital screens, including computers, tablets, e-readers, and smartphones. Nearly 70% of office workers who spend more than six hours per day on screens experience CVS symptoms, leading to reduced productivity and increased stress. The primary risk factors include extended screen exposure without proper ergonomics. The widespread adoption of remote work has further intensified these challenges, making visual strain a critical concern in occupational health.
The purpose of the Study
This study aims to examine the prevalence of Computer Vision Syndrome among office workers and assess the effectiveness of preventive measures in reducing its symptoms.
Materials and Methods:
The study was conducted among office workers who spend at least six hours per day on digital screens. The primary data collection tool was the Computer Vision Syndrome Questionnaire (CVS-Q). The research was carried out in two phases. The first stage measured the prevalence and severity of CVS symptoms among workers. On a second stage workers were provided with preventive recommendations, and a follow-up survey was conducted four weeks later to assess the impact of these measures. Quantitative analysis was used to compare the results of the initial and follow-up assessments.
Results:
The initial survey revealed an average CVS-Q score of 9.75 among participants, with all respondents (100%) scoring 6 or higher, confirming the presence of CVS. After four weeks of following the recommended preventive measures, there was a significant reduction in symptoms. The proportion of workers with a CVS-Q score ≥6 decreased from 100% (18 workers) to 16% (3 workers). Additionally, the average CVS-Q score dropped nearly by half, from 9.75 to 4.5 points. These findings demonstrate the effectiveness of preventive interventions and high compliance among workers in mitigating the symptoms of Computer Vision Syndrome.Conclusions:
: 1. Digitalization has significantly increased visual strain among office workers, contributing to the widespread occurrence of Computer Vision Syndrome. 2. CVS negatively impacts productivity by reducing concentration, slowing task completion, and increasing errors, leading to economic losses for businesses. 3. A comprehensive approach to prevention and management – including workplace ergonomics, screen breaks, and awareness programs – can effectively reduce symptoms and improve workers’ quality of life. 4. Implementing preventive programs at the enterprise level is essential, along with further research to refine and optimize existing recommendations.
