Relationship between low-frequency electromagnetic field and computer vision syndrome
Abstract
Overview
The study was conducted to evaluate the prevalence of Computer Vision Syndrome (CVS) among secretaries in a Turkish university hospital and explore its connection with exposure to low-frequency electromagnetic fields (LF-EMF).
Subjects and Methods
In this cross-sectional study, a total of 143 secretaries underwent comprehensive eye examinations, answered the CVS Syndrome Questionnaire (CVS-Q), and had their work environments tested for LF-EMF using a 6010 Gauss/Teslameter device. Light intensity was measured with an LX-1102 Device.
Findings
- The average age of the participants was 39.6 years, with a gender distribution of 25.2% male to 74.8% female.
- High prevalence of CVS was observed (83.9% as measured by CVS-Q).
- A positive correlation existed between CVS-Q scores and LF-EMF levels.
- Significant correlation noted between higher LF-EMF levels and cases diagnosed with CVS; increased risk of CVS by over three times when LF-EMF exceeded 1,725 µT.
- Negative impacts of LF-EMF on tear production measured by Schirmer test were noted.
Conclusion
There is a noted relationship between exposure to LF-EMFs, CVS, and dry eye conditions. Recommendations include regular monitoring of EMF levels and advocating for protective practices such as regular breaks and the "20-20-20" rule to mitigate risks.
