[Changes in the functional state of the visual analyzer during work at video display terminals of graphic images]

The examination covered female operators of sewing pickup, engaged into the work at video-displays. The total work load appeared to equal 77.6% and the work at video-display--75.2% of the shift time. Functional state of the vision demonstrated a decrease even after 2 hrs of the work, then stabilized by midpoint of the shift and afterwards lowered by 10-12 hrs of the work. Those objective changes correlated with the sensation of orbital discomfort. The findings served as a base for prophylaxis to restore the performance during the regulated breaks.
