Glare in one of the major factors influencing comfort appraisal for lighting. Although a predictive formula for such glare has been proposed by CIE, it has not been investigated for domestic adjustment. The correlation between glare and the closely related dazzling-sensation has not been investigated enough. In the study, subjective discomfort glare appraisal and dazzling-sensation appraisal for discomfort glare was performed to produce a corrected UGR formula. Analyses between appraisal for dazzling-sensation and results of subjective appraisal for discomfort glare were performed to produce a formula that could represent the correlation between discomfort glare and dazzling-sensation. The results of the comparison and analysis is that results computed by UGR differed from those of subjective perception, so a corrected UGR formula and corrected glare index and dazzling-sensation was produced. Also, a formula that could represent the state of dazzling-sensation verying with change of luminance was produce.
