To attain advantageous ventilation of the interior of the goggles and to enable manufacture and assembly at a favorable cost, the securing devices can be joined in a form-fitting manner to the frame and have vent openings for ventilating the interior of the goggles. In particular, the securing devices can be snapped into recesses in the frame, and vent openings formed in the securing devices can be selectively opened or closed by means of a covering plate that is attached by screwing. | |
