There are uncertainties in the current daylight glare prediction models as they do not accurately predict the glare sensation that people experience. The objective of this research project is to investigate daylight glare stemming from contrast between task area and its immediate surroundings. In order to control for bias, several of the main factors that are suspected of influencing individuals’ glare ratings will also be investigated, among others self-reported glare sensitivity, gaze direction and eye contrast sensitivity. The expected research outcome is an improvement of the current daylight glare prediction models.
