Abstract: A method for controlling an artificial iris comprises: receiving a measurement of light intensity detected by a sensor on or adjacent to the artificial iris; accessing a user-specific profile based on user calibration for determining one or more user-specific thresholds of light intensity of the user-specific profile, wherein the one or more user-specific thresholds are associated with light intensities for triggering a change of light transmittance through the artificial iris; comparing the received measurement of light intensity to the one or more thresholds in the user-specific profile; and determining, based on said comparing, whether to turn on or turn off one or more concentric rings of liquid crystals of the artificial iris for controlling an amount of light transmitted through the artificial iris.

Abstract: A smart contact lens (400) for detecting a ratiometric change in an incident light (126) intensity is provided, including one or more, preferably concentric, rings (410-1, 410-2, . . . , 410-N) 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 (420, 100, 101) for detecting a ratiometric change in an incident light intensity; and a controller (430) configured to operate the one or more rings based on an intensity of an incident light and to, as a response to the circuit (420, 100, 10 101) detecting a ratiometric change in the intensity of the incident light from a higher intensity state to a lower intensity state indicating that at least a beginning of a blinking of an eye of a user has occurred, initiate a re-polarization of the one or more rings. A method of operating the smart contact lens and various uses of the circuit are also provided.
