Abstract

Anti-glare device for use in protective goggles, safety helmets or protective masks for welders having at least one optical detector (1) and one non-optical detector (9), which non-optical detector detects interference sources, in particular electromagnetic interference fields. The signals of the two detectors are fed to an electronic switch (5) which, for example, has a logic circuit, in order to generate control signals, which are free of interference sources, for the liquid-crystal cell (7). The non-optical detector (9) can be freely positioned and can also transmit the detector signals in a wireless fashion or by optical fibre. <IMAGE>
