| 20100146685 | FORCED-AIR PROTECTIVE APPARATUS - An article for protecting a wearer's eyes from air-entrained particulate matter in close proximity to the eyes includes a frame, a conduit and a connector. The frame is to be placed on the head at least partially encircling the eyes of the wearer. The conduit is supported by the frame and includes a discharge outlet therein for discharging a gas under pressure into the area forward of the wearer's eyes to form a zone of relatively high pressure and propel particulate matter away from the eyes. The connector is carried by the conduit for connecting the conduit to a pressurized source of gas.
