George V. Boos, Ph. D., RANS Academician, Winner of the State Prize of the Russian Federation, President of ILEC BL GROUP, head of the Light-Engineering sub-department of NIU MEI, Chairman of the Science and Engineering Board of the Russian light and engineering industry, head of the Interstate Technical Committee and the National Technical Committee 332 of Rosstandart (Light Engineering and Artificial Lighting). In 1986, he graduated from Moscow Power Engineering Institute (MPEI), engineer electrician qualification, specialty in Light and Engineering and Light Sources

Vladimir P. Budak, Professor, Doctor of Technical Sciences. In 1981, he graduated from the Moscow Power Engineering Institute (MPEI). At present, he is the Editor-in-chief of the Svetotekhnika / Light & Engineering journal, Professor of the Light Engineering sub-department of NRU MPEI. Corresponding member of the Academy of Electrotechnical Sciences of Russia

Ekaterina I. Ilyina, Postgraduate student of the NRU MPEI. Research interests: psychophysical scale of visual perception, unified glare rating (UGR), neural networks, and near field of light devices

Tatiana V. Meshkova, Ph.D. She works as a senior scientific editor in the Light & Engineering journal and teaches a course on illumination design at Light and Engineering chair of the NRU MPEI. Her research interests are in the quality of lighting, visual experiments, and discomfort

Light forms view of the environment and can influence the psychoemotional state in it. Human centric lighting was introduced after the receptor responsible for the effect of illumination on the circadian rhythm, that is, the nonvisual effect of light on the human body, was discovered. To form the concept of human centric lighting requires a holistic approach that takes into account both visual tasks and the psychoemotional state of users in this environment. The degree of discomfort may increase if there are glare light sources in the field of view. Insufficient monotonous illumination with sharp changes in luminance or contrast, which can be estimated using the spatialangular distribution of luminance, can also cause discomfort. The article proposes an experimental approach to assess the quality of illumination in laboratory conditions.
