<p>Disclosed is an apparatus and methodology for operating an automatic darkening filter (ADF) eye protection device. An operating voltage is alternately applied to a pair of control terminals of an ADF device circuit in a continuing sequence where a first polarity voltage is applied to the pair of terminals and then reversed. A delay period is provided between application of the alternating polarities. In some embodiments ground potential is applied to both terminals of the pair of terminals during the delay period.</p>
