Summary
This systematic review and meta-analysis examines how light, mediated through intrinsically photosensitive retinal ganglion cells (ipRGCs), affects human wellbeing across multiple non-visual domains. The findings have practical implications for lighting designers seeking to use standardized metrics (e.g., melanopic EDI per CIE guidelines) to optimize light environments for health and mood outcomes.
Key Findings
- The review focuses on ipRGC-mediated non-visual effects of light on wellbeing, encompassing circadian, mood, and health-related outcomes.
- Utilizes CIE standardized photometric systems to quantify and compare light exposures across studies, supporting evidence-based lighting design.
- As the abstract is truncated, specific quantitative effect sizes or p-values from the meta-analysis are not available from the provided information.
