Allen Keen 4140 Youth Safety Glasses Clear Lens Lime Green Frame

The Allen Keen 4140 Youth Safety Glasses deliver ANSI Z87.1-rated eye protection specifically sized for younger shooters and outdoor enthusiasts. These impact-resistant safety glasses feature a vibrant lime green frame that's easy to spot and clear polycarbonate lenses that provide 99.9% UV protection without color distortion.

What Makes This Different

Unlike adult-sized safety glasses that slip and slide on smaller faces, the Allen Keen 4140 features a youth-specific frame geometry with reduced temple length and bridge width. The lightweight polycarbonate construction weighs just 0.8 ounces, making extended wear comfortable for young shooters during training sessions or competitions. The wraparound design provides superior side impact protection compared to standard rectangular frames.
