L’illuminamento corneale nella progettazione illuminotecnica. Un nuovo indice di valutazione del comfort visivo in ambiente interno - The corneal illuminance in lighting design: a new evaluation index of visual comfort in the indoor environment
In recent times, the research in the field of non-visual effects of light has produced significant results, and the importance of the corneal illuminance for lighting design purposes has gradually increased. In some cases, it has been identified as the vertical illuminance at eye level, and its importance has emerged with reference to various factors, such as melatonin production. The latter has beneficial properties on the immune system, but above all on the regularization of the circadian rhythm, namely the cyclical variation of our natural and biological activities.
