Safety eyewear which meets performance standards of ANSI Z87.1 is impact resistant but not unbreakable. High impact lenses (polycarbonate) are recommended because they provide more impact resistance than basic impact lenses (plastic or glass). Basic impact lenses should not be worn where there is more than slow speed or low mass impact hazards. Exposure to or contact with chemical vapors or liquid may cause crazing. Pitted or scratched lenses reduce vision and significantly reduce impact protection. Replace damaged eyewear immediately. For protection against hazards from the side, eyewear must be worn with sideshields. Eyewear will not protect against severe impact hazards, such as fragmenting grinding wheels, explosive devices, high speed or large mass flying objects, chemical splash or similar hazards. Machine guards, engineered devices or additional personal protective equipment must be used for these hazards. Use of improper protectors can cause serious eye damage, including blindness. Consult with professional safety personnel or refer to a selection chart for the correct personal protective equipment. Clean only with approved lens cleaning products.
