Information technology (IT) has increased and changed the load for individuals in the workplace. Small displays and small text size on many IT applications leads to a reduced viewing distance and poorer posture with increasing biomechanical and oculomotor loads as a result. Mental stress related to the high amount of information received and processed contributes in parallel to increase the level of activity in the neck/shoulder/arm muscles.
Demographic trends also mean that the proportion of older workers who regularly perform visually demanding work has increased. When the visual system’s muscles, sensory and/or perceptual functions are subjected to high levels of demands that are outside that for which the eyes are evolutionarily adapted to cope with, this impacts on health and wellbeing. The overall goal of my current research, in this context, is to explore and describe linkages between visually deficient work conditions and its effects on physical and mental health and performance
