摘要

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.
