Means for controlling the Akkommodationsbedarfserfassung in an ophthalmic technical system (OTS) (6) comprising at least one sensor (1) for detecting a body's own signal sequence, or an environment signal sequence and converting this in measurement signals (3) and at least one detection unit (4) for converting the measurement signals (3) into a control signal (5), which influences the Akkommodationsbedarfserfassung. The object is to make these agents so that a significant energy saving of an artificial accommodation possible without a substantial reduction of the user (or OTS) or the user convenience is increased. The object is achieved in that the detection unit (4) comprises a signal detection, which compares the measured signals (3) with a reference signal bandwidth and with an overlap of the measurement signals by a predetermined reference signal bandwidth, the control signal (5) generated.
