Currently, to use the experimental formula for discomfort glare studied abroad, it would be not appropriate because each races feel about the degree of glare differently. Therefore, this study aims to make up prediction formula for evaluating discomfort glare reasonably from Koreans' vision, and it proceeded with 4 stages as follows: First, after reviewing the existing discomfort
glare evaluation formula, I selected experimental variables. Second, I made a mock-up that I can control experimental variables and conditions according to the purpose of this study. Third, I conducted discomfort glare evaluation experiment. Finally, compared with UGR evaluation method suggested for Westerner in prior studies.
In conclusion, 1) it's proved that discomfort glare is influenced highly by a light source luminance, background luminance and location of testee and the line of vision. 2) In interior discomfort glare experiment, whether the glare light source is placed within range of vision or not has more significant influence than the distance between the light source and testee. 3) I compared and analyzed with UGR, the most representative discomfort glare evaluation system, and I found there is a little difference in the results. This shows discomfort glare of Koreans and Westerners are different.
