Abstract
An eye protective device having a frame member and a shield member attached to the frame member, the shield member having end portions which have tapered configurations. A pliant foam plastic member has a groove therein, the end portions of the groove having undercut tapered configurations which generally correspond to the tapered configurations of the end portions of the shield member. The tapered end portions of the groove engage the tapered end portions of the shield member so that the foam plastic member is held in place snugly against a wearer's face just above the eyes of the wearer during use so as to prevent perspiration or other debris from falling into the wearer's eyes.
