Technical Field

The invention relates to the technical field of protective masks, in particular to a mask capable of being loaded with glasses.

Background

Many work environments require workers to wear full facepiece respirators, such as chemical workers, firefighters, and other personnel working in environments where air pollutants are present. However, many times workers who need to wear such full face masks also need corrective lenses due to myopia and for various reasons they are unable to wear contact lenses.

While the face seal of a full face mask is typically made of silicone or similar material to form a seal around the wearer's mouth, nose and eyes. The seal typically relies on contact between the soft material of the face seal and the wearer's skin. Facial hair or whiskers often detract from the ability of the facial components to form a positive, leak-proof seal. For this reason, most full face masks do not cover the wearer's ears. Conventional lens eyeglasses typically include temples extending from the frame of the lens eyeglasses that span the wearer's temples and attach around the wearer's ears. Thus, these temple pieces need to pass under the edge of the face seal, thereby reducing the seal integrity and reducing the protective effectiveness.
