Background: The aim of this study was to assess the impact of the visual work with display monitors on the eye surface temperature, intraocular pressure and on the eye moisturizing condition. Materials and Methods: The study was conducted among 50 people working with display monitors (CRT, LCD) and without monitor. The temperature of the eye surface via thermo camera and intraocular pressure were measured, as well as Schirmer's test was performed before and after 4 h of visual work. Thermography was also performed after 1 h. Results: The studies revealed no significant effect of all visual works in patients with normal tear secretion. Only among those with dry eye syndrome, statistically significant increase in the eye surface temperature was found and averaged 0.5(degrees)C after 4 h of all visual works. Conclusion: The studies revealed that intensive visual work with CRT and LCD display monitors and without monitor causes changes in the eye surface temperature, especially after the first hour of visual work and in patients with dry eye syndrome. The results of tonometry showed that all visual works at a short distance lead to the decreased intraocular pressure, resulting from the improved aqueous humor outflow. Finally, no negative effects of the visual work with the display monitor on the eye was found. However, the appropriate duration of work and application of tear substitutes play an important role in people with the symptoms of dry eye syndrome.
