The purpose of this paper is to identify the range of the total amount glare by using the average luminance of the visual field. Two series of experiments were carried out. In the first experiment, the pre-adaptation level equals the background luminance, and in the second, the pre-adaptation level is constant. The curve indicating the relationship between the luminance and glare sensation for the field with uniform luminance is obtained. The first experiment shows a significant difference in glare sensation, when the ratio of background luminance to source luminance is different, even when the average luminance of the visual field is the same. The second experiment shows that the effects of the ratio of background luminance to source luminance on glare sensation are not significant and that the average luminance can be used to predict glare sensation. The effect of the pre-adaptation level on glare sensation is also discussed.
