Abstract
The present invention describes goggles for protection against gases having a resilient frame with two eye spaces each surrounding an eye of the user. The eye spaces are surrounded by mounts which hold the lenses in place. In order to obtain a firm fit and the required sealing-tightness between the lenses and the mounts, the surface of the front edge of the mount is formed with a peripheral groove in which a rigid ring is secured. This ring applies pressure to the surface of the front edge of the mount sealingly securing the lens in a recess in the mount.
