The XV100 Series Safety Glasses not only protect your eyes from mishaps but they are also comfortable enough for all-day wear. They feature a 10-base, wrap-around clear uni-lens for great peripheral vision and protection. The lenses have a Uvextra anti-fog coating and an anti-scratch Hardcoat for maximum durability. The clear frosted, polycarbonate frame has a lightweight design and thin, shaped polycarbonate temples for all-day comfort. They also feature a molded, universal nosepiece for an easy fit. The XV100 Safety Glasses have earned an ANSI Z87.1-2010 Standards for use in industrial applications rating because they have endured extensive testing for optical clarity, impact resistance and proper eye coverage.
