Flicker threshold
WebCritical flicker fusion thresholds were reduced in retinal/neural disease but resistant to image degradation from media opacity. The 1.5-degree stimulus had 88 % sensitivity and … WebFlicker thresholds for refresh rates between 40 and 100 Hz were estimated by asking subjects to increase the luminance of the display until they first saw flicker (ascending flicker thresholds) and then to decrease the luminance of the display until they no longer could perceive flicker (descending flicker thresholds).
