Description

<p>Light input through the eye significantly impacts human health and well-being by regulating circadian rhythms, sleep, neuroendocrine, and cognitive functions. Evaluating light is crucial for ensuring an appropriate lighting environment, with photometric units based on illuminance currently being the norm. However, illuminance, a unit based on visual light sensitivity, does not adequately assess non-visual effects such as circadian rhythm phase shifts and melatonin secretion suppression. This paper outlines the background to the establishment of melanopic equivalent daylight illuminance (EDI), a new international standard for quantitatively evaluating the non-visual effects of light, and indoor lighting recommendations based on this standard.</p>
