Eye and Face Protectors
How do I recognize safety eye wear?
Lenses: CSA-certified eye and face protectors must meet the criteria for impact resistance as outlined in the standard. Only devices made of approved materials are permitted.
Markings: The manufacturer or supplier certification mark must be present on all approved safety lenses, frames (front and temple), removable side shields, and other parts of the glasses, goggles, or helmets.
Frames: Safety frames are stronger than street-wear frames and are often heat resistant. They are also designed to prevent lenses from being pushed into the eyes.

What should I know about the fit and care of eye wear?
Eye wear will protect the user if the eye and surrounding soft tissues are fully covered by the protection device. If eye protection is required, establish a complete eye safety protection program including selection, fit testing, training, maintenance and inspection.
Fit
- Ensure your safety eye wear fits properly. Eye wear should cover from the eyebrow to the cheekbone, and across from the nose to the boney area on the outside of the face and eyes. Eye size, bridge size and temple length all vary. Eye wear should be individually assigned and fitted so that gaps between the edges of the device and the face are kept to a minimum.
- Eye wear should fit over the temples comfortably and over the ears. The frame should be as close to the face as possible and adequately supported by the bridge of the nose.
- Users should be able to see in all directions without any major obstructions in their field of view.
Care
Eye and face protection devices need maintenance.
- Clean your devices daily. Follow the manufacturer's instructions.
- Avoid rough handling that can scratch lenses. Scratches impair vision and can weaken lenses.
- Store your devices in a clean, dry place where they cannot fall or be stepped on. Keep them in a case when they are not being worn.
- Replace scratched, pitted, broken, bent or ill-fitting devices immediately. Damaged devices interfere with vision and do not provide protection.
- Replace damaged parts only with identical parts from the original manufacturer to ensure the same safety rating.
- Do not change or modify the protective device.
What should I know about lens colours?
Lenses can be clear, tinted, photochromic or polarized. Each type offers various levels of ultraviolet protection, including no protection (even when coloured). Do not be fooled by the colour of the lenses.
Conduct a hazard assessment to identify the hazards that workers may be exposed to, and then select appropriate PPE when engineering controls or other more permanent methods of control are not possible. Consult with the PPE manufacturer about the uses and limitations for each type of eye or face protection.
How do I select the proper eye and face protection?
If you are at risk for eye or face injury at work, you should wear appropriate protection.
To select the proper protectors follow the recommendations in the table below.
Note: This table cannot cover all possible hazards and combinations that may occur. Examine each situation carefully and select the appropriate protector or combination of protectors.
