Protective glasses include a curved lens panel for protecting the eyes. Two side pieces have an inner end articulated on a helmet and an outer end articulated on the lens panel. The glasses are pivotable from a protective position to a stowed position. Each side piece includes a glasses arm and a glasses-carrying arm. The glasses arms are curved in the direction of the lens panel and adjoin the lens panel tangentially. The glasses arms have axes of articulation that are not aligned with one another. In the stowed position, the protective glasses are in a helmet and can be moved into, and out of, the stowed position using one hand, without length of the side pieces or tilt of the lens panel in relation to the side pieces being changed. One-handed actuation of the glasses is very advantageous in forestry work, in the industrial sector or for climbing purposes.
