Protective filters in the prevention of asthenopia at a video display terminal.
In this work 25,064 employees were studied with the aim of investigating whether the video display terminal (VDT) equipped with filters reduces the incidence of asthenopia with reference to weekly time spent at a VDT and duration of work at a VDT. Analysis showed that the filters themselves do not reduce the occurrence of asthenopia consequent to various factors (refractive defects, time spent at a VDT, and monitors' characteristics).
