one or more, preferably concentric, rings of a liquid crystal display, LCD, type, each ring being operable between a state having a lower attenuation of light and a state having a higher attenuation of light;
a circuit for detecting a ratiometric change in an incident light intensity; and
a controller configured to operate the one or more rings based on an intensity of an incident light and to, as a response to the circuit detecting a ratiometric change in the intensity of the incident light from a higher intensity state to a lower intensity state indicating that blinking of an eye is detected, initiate a re-polarization of the one or more rings.
