Light plays a very important role in a human life, especially artificial light allowing work and perform any activities after dark. Glare is one of the most important lighting quality parameter. It is accompanying the process of vision that affect human visual comfort, wellbeing and performance. It could be also the indirect reason of accidents at workplaces and other illuminated public and private areas. Depending on the type of glare (discomfort, disability, blinding) the accompanying risk is of different level [1]. International standards and CIE documents define rules for discomfort glare assessment and application of relevant index: Unified Glare Rating (UGR) for indoor workplaces [2, 3, 4]. Additionally the development of application of imaging luminance measuring device (ILMD) allows for practical measurement of UGR. The formula for UGR determination and related requirements for maximum limit values of UGR are known for many years. However the studies concern glare assessment are still being carried out. They concern both exploration for a new glare metrics and development of new measurement methods for objective glare assessment. It is worth noting at this point that the measurement of glare refers to two independent issues:  measurement under real conditions in order to assess the glare, based on UGR determination,  measurement for testing glare perception under different glaring conditions and for the development of measurement methods. Conditions and rules of both issues of glare measurements are different. Despite the passage of many years from the beginning of glare research, no standard of conducting laboratory experiments was proposed. Each researcher conducts study according to his own original method and his own procedures, using equipment available in his own laboratory. This is due to the variety of factors affecting glare and the complexity of the research process. It is also difficul[...]
