In this paper, the influence of the Correlated Colour Temperature (CCT) of luminaires on perceived overhead glare was investigated using subjective evaluation methodologies. The study included two sessions, each session addressing luminaires with a given CCT. For each type of luminaire overhead glare was evaluated at various luminance levels with a methodology: semantic differential scaling. A within-subject analysis of variance (ANOVA) with perceived glare as dependent variable and luminance level and CCT of the luminaire as independent variables was adopted to analyse the results. It showed that the influence of both luminance level and CCT of luminaire on overhead glare was statistically significant. The higher the luminance, the more overhead glare was perceived. The luminaires with high CCT yielded more glare than the ones with low CCT. In addition, we didn't find a significant effect of both gender and visual correction means on overhead glare.
