The invention relates to a face and antiglare protection device (1) for observing an object field or a workplace with light intensity differences varying in time and/or space of, for example, 10000:1, as in welding operations. The device (1) comprises at least one camera (4) for generating electronic image signals, at least one sensor (5) for generating electronic measuring data, at least one electronic system (8) for processing the image signals and the measuring data and at least one display for the optical representation of the object field and the measured data. According to the invention, the device comprises at least two electronic cameras (4) having a different spectral and/or spatial resolution. The electronic system (8) is provided with image analyzing means which analyze the image signals captured by said electronical cameras (4) and, preferably, the measuring data of the at least one sensor (5). The electronic system (8) further comprises means of generating a virtual image of the object field, wherein said means synthesize the analyzed image signals to form a virtual image such that the entire object field can be recognized in detail on the display by the human eye irrespective of its spectral and topological conditions.
