Understanding the vision-body relation: A key to VDU-workplace improvements. An empirical study based on ecological explications and a systemic approach to vision.

The extensive use of information technology (IT) and video display units (VDU) in modern work-life has engendered an increasing concern about potential negative health effects.

The theoretical viewpoints from where traditional ergonomic work emanates are however, monocausal and unidirectional in that they predict individual work related symptoms from work site environmental conditions or from intrapersonal factors, alone. It is a question whether such theories have the flexibility necessary to explain the heterogeneous and often subtle composite of complaints found among VDU-workers. This project is based on a theoretical proposal combining interactional theoretical perspectives with knowledge about human ecology. The primary objective is to study relations between functional fatigue of the ocular musclar system, musculosceletal problems and subjective symptoms. The project is theoretically anchored within cognitive/sensory neuropsychology, psychophysiology and muscle physiology, but it also capitalises on adjacent fields like optometry, ecological psychology, health psychology and evolutionary psychology. This objective is studied in a series of experiments, accomplished both in the laboratory and in field settings. The project yield increased understanding not only for problems associated with VDU-work, but also for visual nearpoint stress in a broader context.
