As the conventional lighting techniques are based on horizontal workplane illuminance, it drives from the vertical eye level illuminance and its spectral distribution triggering the non-visual effects on humans. That is named as melanopic illuminance consequently. Its metrics have taken their place in lighting design literature and applications, with emergence of related standards subsequently. This literature overview contributes about the understanding the meaning human centric lighting due to transition from visual to non-visual effects of light, and how they direct recent research through light's impacts on human performance, emotions health and well-being, and relations to energy saving even. The shift from the concept of human centric lighting to circadian lighting design is obvious in very current studies. © 2023 IEEE.eninfo:eu-repo/semantics/openAccessCircadian lightingHuman centric lightingNon-visual effectsVisual effectsEnergy conservationConference Object2-s2.0-8516865885810.1109/EEEIC/ICPSEurope57605.2023.10194800
