Relationship between low-frequency electromagnetic field and computer vision syndrome
Abstract
Overview
This study investigates the prevalence and risk factors associated with computer vision syndrome (CVS) among secretaries working in different departments of a university hospital in Turkey, specifically exploring the influence of low-frequency electromagnetic field (LF-EMF) exposure.
Subjects and Methods
- A total of 143 secretaries from various departments were included in this cross-sectional study.
- Participants underwent eye examinations and completed the CVS Syndrome Questionnaire (CVS-Q) and Ocular Surface Disease Index Scale (OSDI).
- Environmental LF-EMF was measured using a 6010 Gauss/Teslameter, and light intensity with an LX-1102 Device.
Findings
The study found:
- The average age of participants was 39.6 years, predominantly female (74.8%).
- A high prevalence (83.9%) of computer vision syndrome was observed.
- A weak positive correlation between CVS-Q scores and LF-EMF levels was noted. Conversely, a moderately strong negative correlation was observed with the Schirmer test for both eyes.
- Significantly higher work environment LF-EMF values were detected in participants diagnosed with CVS.
- The risk of developing CVS was 3.27 times higher when ambient LF-EMF exceeded 1,725 µT.
Conclusion
A direct relationship has been established between exposure to LF-EMF, the occurrence of CVS, and dry eye symptoms. It is recommended to regularly measure EMF levels in work environments and encourage protective behaviors to mitigate these health risks.
