Subjective and Objective Aspects of Headlamp Glare: Effects of Size and Spectral211 Power Distribution

摘要

In the formal study of glare, a major distinction has been made between211u001esubjective and objective effects of glare (referred to as discomfort glare and 211u001edisability glare, respectively). Recently, both anecdotal reports and formal 211u001eexperiments have indicated that headlamp size and spectral power distribution 211u001eaffect discomfort glare, but no assessment has been made of whether these two 211u001efactors also affect disability glare. Models of disability glare suggest that 211u001ethey should not. The present experiment was designed to provide empirical 211u001eevidence about this issue.
