1. A wearable electro-optical device comprising:
an electrochromic layer of active electrochromic components dissolved in a polymer matrix, wherein the electrochromic layer comprises an electrochromic composition comprising a cathodic component in the form of a quaternary salt of dipyridine and an anodic component;
a controller electrically coupled to the electrochromic layer and configured to apply a controlling voltage to the electrochromic layer causing an electric charge to pass through the electrochromic layer in response to a received control command to vary light transmittance of the electrochromic layer; and
a power source for supplying electrical power to the controller.
