| Abstract |
Visual discomfort glare in daylight interior environment is main issue for healthy buildings. Existing studies have been conducted in the limited visual field and binocular visual field. The sensation of discomfort glare should be verified in whole visual field and monocular visual field for position index. The objective of this study is to investigate discomfort glare sensation of binocular and monocular visual field over the entire visual field. Total of 225 conditions for each person were tested on a glare tester. Three types of tests, the average visual field, the luminance of the borderline between comfort and discomfort (BCD) at sixteen radial angles and the BCD luminance on line of sight were measured using the kinetic method. The results show that the distribution of glare sensation of binocular and integrated monocular visual field have no significant differences. The left monocular visual field and right monocular visual field were symmetrical each other. This results can be used not only to develop discomfort glare formula but also to create comfortable indoor places. |
