Abstract:
A respiratory mask is provided with an eye shield having a body portion which is releasably-secured to the mask, and a shield portion which shields the eyes of the wearer. The shield portion is self-supporting on the body portion and, hence, on the mask, and includes a sheet of transparent, eye-shielding, material which can be replaced if it becomes marked or damaged. The shield portion can be pivoted forwards, relative to the mask, so that it is removed from the line of vision of the wearer without affecting the respiratory protection provided by the mask. A valve arrangement in the body portion of the eye shield can divert air from the mask into the shield portion, to remove contaminants from the region around the eyes of the wearer.
