The vertical vehicle dynamics causes glare stimuli on the oncoming driver's eye during nighttime driving. In order to investigate the effect of these glare stimuli on the human vision, a description of dynamic glare is presented for the time range from 0.3 second to 10 seconds. An adaptation model explains the disability glare effect, it allows determining the readaptation time by computing the temporal course of the threshold enhancement factor. The discomfort glare aspect is examined by the evaluation of observers with the dynamic glare rate. An equation is derived, which is able to calculate the dynamic discomfort glare rate for glare stimuli of rectangular shape. For the covering abstract see ITRD E123380.
