Summary
This cross-sectional study of 140 telemarketing workers found that continuous screen use (96.4% of the workday) did not produce significant changes in refractive errors over four years, but 41% of workers reported visual fatigue or asthenopia symptoms. These findings highlight the need for preventive measures in screen-intensive work environments, such as optimized display lighting, ergonomic adjustments, and regular visual breaks.
Key Findings
- 41% of teleoperators reported symptoms of visual fatigue (asthenopia) associated with prolonged screen use.
- Most common visual pathology was myopia combined with astigmatism (37%), followed by myopia alone (33%).
- 54% of workers using visual correction showed no changes in prescription over the past 4 years, suggesting continuous screen use did not significantly worsen refractive errors.
- 96.4% of the workday was spent using screens (PVD), with a mean work experience of 75 months.
- 59% of workers required visual correction; mean age was 36 years.
