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 includes receiving from a light sensor a measured illuminance of the environment of a wearer, computing a change of illuminance measured during a predetermined time interval, comparing the computed change of illuminance with a first threshold, when the computed change of illuminance is greater than the first threshold, implementing first command configured for varying the transmission of the variable transmission ophthalmic lens from 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.
