Contribution of Melanopsin to Discomfort Glare Perception

Journal of the Illuminating Engineering Institute of Japan, 2021
Blue light often causes discomfort glare, but it is unclear which visual pigments are the main contributing factors. Thus, we conducted an experiment to clarify the effects of two visual pigments, S-cones and melanopsin-expressing intrinsically ...

Brief Communication: Impact of Sign Panel Luminance on Visual Comfort

Interdisciplinary Journal of Signage and Wayfinding, 2019
Signs should produce useful visual information to road and sidewalk users without creating undue glare or visual distraction. In order to assist in navigation and wayfinding, signs must be sufficiently conspicuous. For this reason their brightnesses are

Prediction of discomfort from glare from daylight in classrooms

Lighting Research & Technology, 2023
Daylighting is desirable in classrooms but can pose a challenge to classroom illumination when there is a risk of discomfort from glare from windows and sunlight. There are several metrics in use for the evaluation of discomfort from glare from daylight,

Predicting discomfort from glare with pedestrian-scale lighting: A comparison of candidate models using four independent datasets

Lighting Research & Technology, 2023
After dark, pedestrians may experience discomfort from glare caused by outdoor lighting. While several models for measuring discomfort have been proposed, there is no consensus as to which model should be used.

Perception of discomfort glare in relation to the CIE Unified Glare Rating scale (UGR) and the impact of ambient light on both UGR and Subjective Glare Indexes (SGIs)

Indoor Environments
The Unified Glare Rating (UGR) method defined by the International Commission on Illumination is practically the only one used for evaluation of discomfort glare in the lighting design process. However, it is unclear if this method aligns with subjective
