Abstract
Abstract A hospital face mask with an integral eye shield is disclosed. The shield prevents foreign bodies from entering a wearer's eyes, such as blood that spurts during surgery. It is made of an anti-glare, anti-fog material. In the preferred embodiment, the shield includes attached sponge strips that space it slightly away from the wearer's face, while still blocking sweat from dripping into the wearer's eyes.
