BISON LIFE BL-KSSG1-CLBT-YGR-12 Keystone Safety Glasses Anti-Scratch Yellow 12 Pair

What this product is

This is a box of 12 pairs of Keystone Series safety glasses from BISON LIFE. The set supplies six pairs with yellow lenses and six pairs with green lenses for workplace eye protection. They are personal protective equipment intended for environments where impact hazards exist. The lightweight polycarbonate construction aims to reduce fatigue during extended wear.

What the mixed lenses change

Having both yellow and green tints in one box lets a team match lens colour to lighting conditions without ordering separate SKUs. Yellow lenses can improve contrast in low light while green lenses reduce glare in bright areas. The anti-scratch coating on all lenses helps maintain optical clarity through daily use. The wrap-around design extends peripheral coverage for each wearer.

The specification that decides fit

The lenses meet ANSI Z 87.1 impact requirements for industrial safety eyewear. Polycarbonate material provides shatter-resistant performance under high-velocity impact. Universal-fit temples are designed to minimise slippage across different head shapes. Buyers who need prescription inserts or a specific optical density rating should verify compatibility before purchase.
