The following paper deals with the question of whether VDUs with positive polarity or negative polarity are preferable from the ergonomic point of view. It discusses to what extent conditions are improved or impaired by changing the image polarity, using the visual performance and the sensitivity to interference as indicators. The basic visual functions of the user, adaptation flicker sensitivity, contrast sensitivity and visual acuity, are less influenced by changing the polarity than would be expected from classical investigations. The sensitivity to interference by reflections of environmental light on the VDU decreases. Because of the lower conspicuity of interference on VDUs with positive polarity, the design of VDU workplaces becomes more flexible. Together with a higher acceptance by the user, positive polarity will represent an ergonomic improvement in comfort. |
