Purpose:
To evaluate the effects of long-term work with computer monitor on the accommodation, convergence, stereopsis, near and distant visual acuity.
Material And Methods:
The studies of the accommodation, convergence, stereopsis, near and distant visual acuity have been performed in 50 employees working with the computer 6.5 hours daily, 5-6 days weekly and 5 to 12 years. The same studies have been performed in 50 white-collar workers, who had no contact with the computer in their work.
Results:
No changes in the accommodation, convergence, stereopsis, near and distant visual acuity have been found in the employees in both studies groups.
Conclusion:
Long-term work with the computer monitor does not cause changes in the visual function of the employees. Reported changes are probably cause by the visual fatigue associated with the near work, and not by the direct influence of the computer monitor.
