Abstract

The effective intensity of flashing lights has been calculated by using the Blondel-Rey-Douglas formula. However, the effective intensity calculated by using this formula can only be applied to the threshold in a dark background. Furthermore, the effective intensity of flashing lights in peripheral vision at the threshold level has not been clarified. Therefore, a visual experiment was conducted to obtain the threshold for flashing lights and steady lights in eccentricities of 1 degree, 5 degrees, and 10 degrees under a background luminance of 0.13 to 10 cd/m₂. The results show the experimental values are higher than the Blondel-Rey-Douglas value under all conditions. The effective intensity calculating method for flashing lights in peripheral vision of the Blondel-Rey-Douglas formula with a revised visual time constant "a" was investigated.
