Abstract: A spectacle lens includes an activable optical filter having at least an electrochromic device and being configured to be actively switched between at least three configurations. In the first configuration, the activable optical filter is uniform. In the second configuration, the activable optical filter attenuates selectively light from a localized light source. In the third configuration, the activable optical filter is uniform. Furthermore, the chromaticity difference ΔChrom between each of the configurations is smaller than or equal to 20.
