450 glare scenes were analyzed to investigate existing discomfort glare metrics. DGP performs best in evaluating imperceptible and intolerable glare scenes. DGI underestimates discomfort glare while VCP and CGI overestimate it. UGR performs best under perceptible and disturbing glare ranges. Existing glare score ranges should be further verified to improve accuracy.
