CSA Z94.3 Rated Safety Glasses
The Canadian Standards Association Z94.3 standard for Eye and Face Protectors applies to eyewear that shields eyes from exposure to a wide range of hazards such as impact, chemical splashes, heat, infrared radiation, molten metal, sparks, ultraviolet light and visible light. Protective eyeglasses that meet this standard are categorized into seven classes.
Prescription Safety Glasses
Prescription frames with a CSA Z94.3 rating provide the level of protection from the hazards indicated on frame or in eyewear descriptions with shatter-resistant lenses. CSA Z94.3 rated safety glasses may also meet other international standards such as the American National Standards Institute Z87.1 standard or European EN 166 standard.
