Summary
This study examines how macular pigment optical density modulates individual sensitivity to discomfort glare from daylight, with implications for personalized lighting comfort standards. The findings suggest that photoreceptor-specific metrics (alpha-opic irradiance for cones and ipRGCs) should be considered when evaluating glare in daylighting design, particularly for populations with varying macular pigment levels.
Key Findings
- Alpha-opic irradiance values were calculated separately for cones and ipRGCs for the sun disc (approximately 5.8° diameter) and at eye level, indicating meaningful differences in photoreceptor-specific stimulation.
- Macular pigment optical density was found to influence individual sensitivity to discomfort glare from daylight, suggesting inter-individual variability should be accounted for in glare assessment frameworks.
