Yellow Lessens Discomfort Glare: Physiological Mechanism(s)

摘要

This report results from a contract tasking TNO Human Factors as follows: The Grantee will investigate the physiological mechanisms behind the perceived glare reduction obtained when using a yellow filter. The proposed project aims to place the reported heightened discomfort glare produced by blue light on a more scientific footing. The physiological mechanism of discomfort glare remains unclear. At least four hypotheses have been proposed: 1. Rod-cone interaction (Dr. Ian Bailey. UC Berkeley School of Optometry. personal communication) 2. Excessive iris contraction (Vos. 1900) 3. Chromatic aberration (Dr. Post. Wright-Patterson Lab. personal communication) 4. S-cone sensitivity (ophthalmological case studies) The research consists of a re- analysis of prior collected data and a new experiment. designed to discriminate among the hypotheses.
