An anti-glare protection device, for example a pair of welding goggles, a welding
mask or a welding helmet, includes a supporting part with a sight opening (3),
an optical filter element arranged in the sight opening, and a protective plate
(1), which is mounted or can be mounted on the supporting part such covering
the optical filter element. For the protection of the filter element against contamination
with dirt and in order to protect the wearer of the anti-glare protection device
against undesirable gases, smoke and dirt, a seal (4) made out of an elastically
compressible material is disposed either between the supporting part and the protective
plate (1) or between the filter element and the protective plate (1).
The seal extends substantially around the sight opening and is advantageously affixed
either to the supporting part, to the protective plate (1), or to the filter element.
