New face masks protect a wearer's eyes against impact by a projectile or the like. In one aspect, the face mask comprising a plurality of frames, each of which is adapted to fit onto the wearer's face around one of the wearer's respective eyes, with each frame having mounted thereon a bar arrangement comprising a plurality of generally vertically directed protective bars. The bars are variably spaced in a horizontal direction and mounted into the respective frames so as to avoid obscuring the wearer's vision in any direction of the wearer's field of vision when both frames mounted onto the wearer's face. A "frame mounting arrangement," which in one embodiment includes a nose guard that is mounted between the frames to be situated over the wearer's nose, and a strap attached to both frames to extend behind the wearer's head, holds both the frames onto the wearer's face such that one of the frames is fitted around one of the wearer's eyes. In various embodiments, the nose guard enables the positions of the frames to be adjusted relative to the nose guard so that they may conform to varying facial contours. In another aspect, in addition to or instead of a bar arrangement a lens arrangement is provided, in which a lens is mounted in one or both frames. To accommodate a lens each frame defines a rim receiving area including an peripheral surface, a ridge extending inwardly from the peripheral surface, and a rear surface depending perpendicularly from the peripheral surface. Each lens' rim, in turn, has an exterior surface having a groove formed therein and a perpendicular rear surface, each rim being adapted so that, when it is mounted onto a respective the frame, the rim's perpendicular rear surface abuts the rear surface of the rim receiving area and the ridge extends into the groove. The rim receiving area's rear surface cooperating with the rim's perpendicular rear surface to inhibit rearward movement by the rim, and the ridge cooperating with the groove to inhibit forward movement by the rim, thereby to facilitate holding of the rim in the respective frame.
