Pentax Steel 400

PENTAX STEEL 400 — Stainless Steel Backbone. Pressure-Free Fit. Certified for the Daily Grind.

The name says it all. The STEEL 400 is built from corrosion-resistant, hypoallergenic stainless steel that’s engineered to outlast the toughest industrial, laboratory, and maintenance environments without flinching. This isn’t a frame that wears out, breaks down, or loses its edge after a few months of hard use. This is long-term, daily-wear prescription safety eyewear built for professionals who show up and deliver — shift after shift, year after year.

Spring hinges flex naturally with every movement, delivering a stable, pressure-free fit that adapts to you instead of fighting you through the workday. Adjustable nose pads let you lock in your perfect frame position and forget about it — no slipping, no constant readjusting, no pressure points grinding away at your focus during demanding tasks. Dial it in once. Stay comfortable all day. The STEEL 400 makes all-day wear feel effortless because that’s exactly what it was designed to do.

When workplace hazards enter the picture, the clear polycarbonate side shields take over without hesitation. Dust, debris, and flying particles — blocked and neutralized before they reach your eyes. The shields stay attached, keeping the STEEL 400 fully ANSI Z87.1 certified for high-mass and high-velocity impact resistance. Stainless steel construction on the outside. Certified armor on the inside. The STEEL 400 delivers both without compromise.

Every prescription order ships with a Z87 OPTICS protective case and cleaning cloth, keeping the STEEL 400 clean, sharp, and ready to go another round tomorrow.
