I have the glasses used as protection when attaching mineral wool insulation on the ceiling. I tried several other glasses and always had at the offfenen glasses the problem that these shod, because you get the respirators never so well attached, always escaping during exhalation some air on the side of the nostrils. This fogged every open glasses. Not so with this model. I think the mask very comfortable to wear. Effective sealing and coating fogged really nothing. For the price absolutely top!
