Protective eyewear has a lens frame containing one or more lenses and temple arms or straps for attaching the eyewear to the head of a wearer. The protective eyewear also includes a brow guard. The brow guard attaches to the lens frame. The brow guard is configured to extend in one direction substantially between the temple arms (or straps) and, in a transverse direction, between spaced edges, one of which edges is disposed adjacent the lens frame, the other of which edges is extended toward the brow of the wearer. The brow guard incorporates a magnetic material for attracting and catching magnetically attractable particles such that the magnetic material assists eliminating the drift of such particles down in the gap between the lens frame and the wearer's brow. Magnetic side shields can be added to the protective eyewear or substituted in place of the magnetic brow guard.
