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 &#x394;Chrom between each of the configurations is smaller than or equal to 20.

The invention relates to an ophthalmic device including an electrically controllable amplitude variation cell, in particular an electrochromic transmission variation cell. More particularly, the cell () comprises a main convex surface on the front. This arrangement makes it possible for the cell to process a lateral luminous flux (RP), unlike cells in the prior art (AA).
