| Abstract: |
Eye protection means for use in combination with eye wear, such as safety glasses, having a brow guard in the form of a surface extending from the upper portion of the eye wear to a portion closely adjacent to the brow of the wearer. In one embodiment of the invention the eye protection means comprises magnetic dust collecting means formed of a ferromagnetic material for securement to the brow guard and arranged so that air-born dust particles falling thereon become trapped thereon, thereby decreasing the potential for entering the eye of the wearer. In another embodiment the dust collecting means comprises at least one layer of material arranged to be secured to the brow guard of the safety glasses and having an adhesive upper surface arranged to trap air-born dust particles falling thereon so as to decrease the potential for such particles entering the eye of the wearer.

1. Eye protection means for use in combination with eye wear, said eye wear having at least one lens and a brow guard in the form of a surface extending laterally inwardly from the upper portion of the eye wear lens over to a position closely adjacent to the brow of the wearer, a dust retentive means in the form of a stack of plural layers of thin material secured to said brow guard, each of said layers having a tacky outer surface and being releasably secured to the underlying layer, whereupon said topmost layer traps dust particles thereon and when full said topmost layer is removed from the stack to expose the tacky surface of the underlying layer to permit said layer to trap air-borne dust particles thereon.
