Summary
This state-of-the-art review examines measurement instruments used to evaluate how light at the eye level affects human health, covering both visual and non-visual biological effects. It highlights the importance of proper light measurement for understanding impacts on alertness, wellbeing, and metabolism, calling for broader engagement with this research area in Brazilian technical and academic communities.
Key Findings
- Higher illuminance levels at the eye can increase activity, alertness, and wellbeing, provided they remain within safe limits.
- Scientific evidence from the 1980s established a link between depressive disorders and light deprivation, confirming non-visual effects of light on human health.
- CIE promoted major symposia in 2004 and 2006 to disseminate research on how light affects human metabolism and psychology.
