Teacher to babies
Others have already recognized the everyday suitability of protective headgear: In Singapore get preschool children and teachers face shields when they return to school. Teacher unions from various US states are also campaigning for visors. Some people may still be remembered the miniature visors for newborns, which were manufactured in a Thai hospital. Other hospitals have now adopted the idea.
Here and there you can also get them in Austria to face. In this country, especially waiters and employees in the trade arm themselves with the transparent visors. They have been standard equipment in hospitals since the pandemic broke out. Christoph Steininger, Virologist from the MedUni Vienna, does not give a clear sight good testimony: “In the mask discussion it was often – and rightly – pointed out that there are only a few meaningful studies on the effectiveness Plastic sights there is no substantial data at all. One can only speculate about its usefulness. After they are anything but dense, their positive effect is doubtful from a virological point of view. ” When it comes to masks, it is now known that “they only protect when they are close together. The shields do not meet this important criterion.”
Eyes covered
Birgit Willinger, Head of the Department of Clinical Microbiology at the AKH Vienna and chair of the Austrian Society for Hygiene, Microbiology and Preventive Medicine (You can find a detailed assessment of the ÖGHMP here), is similarly skeptical: “Visors are by no means equivalent to mouth-nose protection masks when it comes to protection,” she says. However, they could catch larger droplets that are emitted even when speaking louder, coughing, sneezing, or wet pronunciation. “They hit the screen before they hit the other’s mucous membranes.”
Another plus: the facial expressions remain recognizable. That the eyes – along with the nose and mouth, are further entry points for the virus – are protected, she also sees it as an advantage. Do the visors prevent the dangerous grip on the face? Willinger: “What is true is that the shields do not cause itching. It is probably less likely to be tugged at them.” However, there are also application errors with sights. For example, if you put your hands directly on the outside.
