A comparison of methods for determining unified glare rating was performed. An analysis was made based on the results of experiments carried out for a typical office workstation under a controlled lighting environment. The DIALux simulation software and the LMK measuring system were used to calculate the unified glare rating. The main aim of the research was to verify the correctness of these two methods through a subjective glare assessment made by a group of 65 people. A comparison of the unified glare rating values determined by the different objective techniques with the subjective estimation shows that the LMK measurement is the more accurate method.
