Abstract:
Protective eyewear comprising:a lens frame containing one or more lenses and having an upper frame member absent from which is any practical brow-ward shelf providing shielding like a brow guard,means for attaching the eyewear to the head of a wearer;a replaceable, sheet-form magnetic flap for attaching to the lens frames, the flap having upper and under sides and extending laterally between opposite lateral edges and trans-laterally between an outboard edge and an inboard edge, the under side having an outboard margin for perching on and securing to the upper frame member of the lens frame by virtue of the under side's outboard margin being associated with releasable securing means for securing the flap and upper frame member in an alignment such that the flap's inboard edge is extended brow-ward to close up a gap between the inboard edge and the wearer's brow, which thereby has the flap cantilevered as a shielding shelf or brow guard, wherein the magnetic flap incorporates a magnetic material for attracting and catching magnetically attractable particles on the upper side for thereby assisting elimination of the drift of such particles down in said gap between the inboard edge and the wearer's brow; whereby the releasable securing means facilitates replacement of the flap with another if the upper side gets overloaded.
