ANSI Z87.1 Approved Prescription Safety Glasses and Safety Sunglasses: The ANSI Z87.1 standards for optical clarity and impact resistance provides specific requirements on eye and face protection allowed in the workplace. The “American National Standard Practice for Occupational and Educational Eye and Face Protection” implemented the ANSI Z87.1 standard to obligate employers to enforce the use of appropriate eye or face protection when exposed to hazardous materials, liquids, vapors, chemical or other harmful substances. The ANSI Z87.1 is the industrial standard for eyewear where the ANSI Z80.7 is the fashion standard for eyewear.
ANSI Z87.1 Stamped Prescription Safety Glasses and Sunglasses Lenses: Some companies require that the safety glass lenses are stamped with ANSI Z87.1 while others just require that they are approved. This is import to know as not all ANSI Z87.1 approved lenses are stamped. However, typically all ANSI Z87.1 approved sunglasses or glasses will include documentation of such approval in the box. If you have questions regarding a certain frame or lens and if it is stamped or not please do not hesitate to reach out to one of our optical specialists via live chat, email, or phone.
Prescription Safety Glass Lens Material: Lens material is often times a personal choice but when it comes to safety glasses you will always want a polycarbonate or trivex lens. A polycarbonate or trivex lens will be lighter than a glass lens and also shatter proof. When you are wearing prescription safety glasses there is the risk of being hit in the eye with potentially dangerous materials and you would never want a glass lens as it can shatter. A trivex lens will be thicker than polycarbonate but lighter and more durable.
What to Look for in Safety Glass Lens Material: Polycarbonate, Trivex, or an industrial safety lens are typically the ideal lens material for safety glasses as they are shatter proof, impact resistant, lightweight and durable. While a trivex lens will be a visually thicker lens than polycarbonate but is lighter and more durable. However, a high grade polycarbonate lens also meets all ANSI Z87.1 standards and in most cases will work just fine, as it is less expensive than a trivex lens. Most companies will have their own version of a high grade polycarbonate lens, Oakley calls theirs Plutonite, Kaenon’s is SR-91, and Smith is Carbonic (Chromapop is what they refer to as their trivex lenses).
