Markings on safety glasses: The manufacturer or supplier logo is marked (or etched) on all approved safety lenses, frames (front and temple), removable side shields, and other parts of the glasses, goggles, or helmets.
Safety frames are stronger than street-wear frames. They are impact resistant and are often heat resistant. They are also designed to prevent lenses from being pushed into the eyes in case of trauma.
CSA-certified safety glasses must meet the criteria for impact resistance outlined in the standard. Safety glasses are made of polycarbonate or CR39 (plastic) or Trivex. All our safety products complies with the industry standards and are manufactured from the highest quality materials.
