Abstract

The disclosure relates to methods, controlling units, eyeglasses, computer programs and computer-readable storage media for controlling an optical transmission of a variable transmission ophthalmic lens, the method comprising: * receiving (S1) from a light sensor a measured illuminance of the environment of a wearer, * computing (S2) a change of illuminance measured during a predetermined time interval, * comparing (S3) the computed change of illuminance with a first threshold, * when the computed change of illuminance is greater than the first threshold, implementing a first command (S4) configured for varying the transmission of the variable transmission ophthalmic lens from an initial transmission value corresponding to a current transmission value to a first target transmission value, according to a first variation profile comprising a first phase during which the transmission overshoots the first target transmission value, and a second phase during which the transmission returns to the first target transmission value.
