Visual, non-visual and psychological effects of light on the textile and clothing factory workers
Résumé
This interventional survey was conducted to assess the impact of lighting conditions on textile workers’ health, in terms of visual and non-visual symptoms. Our investigation concluded that no one of the six production workshops had normative lighting for all workstations before the intervention phase. A large majority of workers were concerned with visual and general symptoms, notably those affected to high visual constraining activities with a non-normative luminance level. The intervention phase was associated with an important decrease of visual symptoms (70.04%) and of non-visual ones (16%) especially when the initial deviation from the norms was significant and the tasks were visually constraining.
