<p>Eyewear, such as safety glasses (22), includes means (20, 50) between the brow guard (30) and the brow of the wearer, the means being adapted to trap dust particles. For ferromagnetic particles the means (20) is a magnetic material, and for non-magnetic dust the means (50, Figure 3) has a tacky adhesive layer (54). Preferably a stack of layers (52) is provided, the layers being discarded when they are dust-laden. </p> |
