Mechanisms for Discomfort Glare in Central Vision [Visual Psychophysics and Physiological Optics]

Conclusions.
Discomfort glare in central vision is more closely associated with the spatial properties of the glare source, such as contrast-defined edges, than the overall amount of light entering the eye. The results suggest that discomfort glare in lighting installations could be reduced while maintaining adequate illuminance levels by an appropriate choice of illuminant source size.
