Abstract [en]

The visual environment can affect our wellbeing in many ways. Insufficient visual ability can lead to increased workload and contribute to eyestrain and musculoskeletal discomfort that in turn could lead to sick leave. Non-visual effects, such as flicker from luminaires can cause eyestrain or headache/migraine. Glare from luminaires or windows within the visual field can cause disability glare or discomfort glare. Glare while performing computer tasks causes visual fatigue and leads to strabismus measured with fixation disparity (harder for the eyes to focus). Strabismus leads to eyestrain, and eyestrain can lead to musculoskeletal discomfort.Although the relation between eyestrain and musculoskeletal discomfort is not fully understood, studies have shown that straining the eyes increases the musculoskeletal activity in the neck and shoulders (muscle trapezius); associations between visually demanding work, eye problems, headaches and/or muscle problems have also been found.The aim of this project is to develop a practical, easy-to-use, and time efficient risk assessment method for visual ergonomics. With this method, risk factors in the visualenvironment can be detected, and interventions implemented to reduce the prevalence of symptoms related to poor visual ergonomics among workers.The developed visual ergonomics risk analysis method has been used at several work places by ergonomists that have been educated in visual ergonomics. The results from the subjective part of the method show that many individuals report eyestrain and headache. This can be caused by many different factors such as wrong power in lenses, glare, flickering lights etc. Therefore it is essential that if you have a visually demanding work (such as computer work) you have to do eye examinations every other year to make sure that your vision is at its best. But the lighting situation at workplaces is also a key factor to consider in a good visual environment, to increase the level of performance. To increase wellbeing at work and reduce sick leave the visual environment needs to be good, with sufficient illuminance, a good luminance ratio, no glare from luminaires or windows,no flicker, and a good visibility of the work task. Education in risk analysis of the visual environment is essential for many different occupations such as lighting designers, ergonomists, working life inspectors, optometrists, to ensure a better understanding of the impact on wellbeing that the visual environment have.The researchers behind this study will have a finished visual ergonomics risk analysis method by the year of 2017.
