Have the glasses ordered to no spatter of my mold spray to get into your eyes. It is easy to handle and very dense. She has my eyes fully protected and completely. She has slipped also to a millimeter. I understand the negative reviews not because my head shape I -denke zumindest- complies with the standard. In the meantime, they also came when cutting trees to use, it has proven itself and you have a good panoramic view.
The spectacle is worth the money and I would buy them again and again
