In order to examine the validity of the existing glare evaluation methods, an experiment with 40 Dutch subjects was conducted using artificial sky and actual sky. First the difference in the sensitivity to glare caused by artificial sky between light colored eye and dark colored eye was examined. The variance analysis showed that there was no significant difference in the evaluation between light colored and dark colored eyes. The result was also compared with PGSV, a glare index derived from an experiment using judgements of Japanese subjects. The evaluation by the Dutch subjects was lower than PGSV in the case of lower source luminance, but it was higher in the case of higher luminance. Further study is required to identify the effect of the cultural difference on sensitivity to glare. Secondly the difference in evaluation between artificial sky and actual sky was examined. Glare sensation against the actual sky was lower than that against artificial sky and PGSV. Luminance distribution of actual sky was less uniform than that of artificial sky and the average color temperature of actual sky was higher than that of artificial sky. However, the difference in luminance distribution and color temperature between the actual sky and the artificial sky did not explain the difference in glare sensation between both skies.
