[Blinking activity during visual display terminal work. 2: reduced blinking and therapeutic approaches].
New findings based on a noninvasive, automated long-term measurement method revealed interindividual differences in lid movement behavior, existence of blinking patterns, and the dominance of cognitive influence in the regulation of blinking frequency during increased concentration and especially visual attention. The development of an individual blinking animation promises long-lasting increase and harmonization of lid movements during visual display work. Maintenance of the integrity of the ocular surface by preventing surface evaporation and providing sufficient precorneal environment eradicates important pathogenic factors of ocular discomfort. An animation program for stimulation of blinking has been developed. First results showed that an increase in blinking rate initiated by the computer itself is feasible in principle during work at a visual display terminal. Further improvement of this new approach is promising.
