Allen 4142 Keen Safety Glasses Clear Lens - ANSI Z87.1 Rated

The Allen 4142 Keen Safety Glasses deliver reliable eye protection with crystal-clear visibility for shooting sports and tactical applications. These ANSI Z87.1+ rated safety glasses combine impact resistance with optical clarity, ensuring shooters maintain target focus while protecting against brass ejection and debris.

What Makes This Different

The Allen 4142 features wraparound lens design that provides 180-degree peripheral protection without compromising sight picture alignment. Unlike basic safety glasses that distort vision at the edges, the Keen model uses optically correct polycarbonate lenses that maintain clarity across the entire field of view. The lightweight frame construction reduces fatigue during extended range sessions while meeting stringent impact resistance standards.
