In 1991 - 1992 a total renovation of two buildings at Alcatel/Telecom Norway, Oslo, was carried out. Unfortunately non-ergonomic luminaries were mounted, and complaints of bad lighting, poor visual conditions, eye fatigue and blurred vision were reported. It was therefore decided to carry out a study of these problems, and in this study we look particular for problems related to the eye problems and optometric corrections. First the lighting and visual conditions were examined in a laboratory study ( Bjorset and Aarfis 1996). At the same time another laboratory study showed that there was significantly lower static trapezius load for sitting position with support of the forearms on the table top compared with sitting and standing without such support. These results were valid for data entry work when using keyboard and mouse ( Aarfis et al. 1997). A multidisciplinary team was established, and the effect of introducing ergonomically luminaries and workplaces and optometric corrections was studied. The three interventions were done in a serial way, and in this study the effect of optometric intervention is evaluated.
Will optometric corrections reduce visual discomfort and headache among VDU-operators.
