Abstract: The present invention relates to a group of novel electrochromic compounds. More specifically, it relates to electrochromic compounds comprising one or several pyridinium rings and the use of these compounds as a variable transmittance medium for the manufacture of an optical article, such as an ophthalmic lens.

Abstract: 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 (3) 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 (IAA).
