The invention relates to the field of management of an active lens and more particularly to a management system comprising an active lens (), a first sensor () arranged to measure data relating to an incident light on the active lens, a control unit () designed for controlling the active lens according to data measured by the first sensor, wherein the management system further comprises a second sensor () arranged to measure data relating to a light transmitted from the incident light through the active lens, the control unit being further designed to adjust, according to said data measured by the second sensor, the control already performed according to said data measured by the first sensor. Thus the management system allows taking into account data relating to the light passing through the active lens as a feedback in order to finely control the active lens.
