Surgical mask

Abstract

A surgical mask provides a wide range of wearers with a good fit and improved comfort, facilitates proper use of the mask, and reduces or eliminates fogging of eyewear, as compared with typical masks. The mask may include a pair of ties that are joined to the upper, central, and lower parts of either side of the body of the mask with the assistance of restraint members. The mask may also include a sealing member that reduces or eliminates gaps between the wearer's face and the upper part of the mask by forming a seal between the wearer's face and the mask in use. In addition, the mask may include a barrier panel that reduces or prevents the wearer's breath from escaping through the mask and rising to the wearer's eyewear.
