FRAME CHOICE Compliance standard: Your frame must meet the compliance standard shown on the job order. This could be CSA (Canadian Standards Association) or ANSI (American National Standards Institute). Some employers allow for both standards. The compliance standard for each frame model is shown in the catalogue. Frame style: Your employer may restrict the style of frame that is available to you. Frame styles include close fit, sealed or semi-sealed and flat frames. In certain cases, employers will also request that frames be non-conductive – most often if the work environment includes electricity. For non-conductive frames, look for the special symbol. Frame material: Your employer may restrict the type of frame materials as shown on the job order. Frame materials are normally metal or plastic. Side shields: Your job order will specify the requirements for side shields as either fixed or removable – or allow the employee to choose. Remember also that that if your compliance standard policy is CSA only, your side shields will only be available as fixed. On most wrap style frames, the side shields is ‘built-in’, commonly referred to as an integrated side shield and treated the same as a fixed side shield. Employer contribution: Frame prices will vary. If your employer has a maximum contribution limit towards your safety prescription eyewear, ensure that you receive a quote from the clinic before proceeding with your order.

LENS CHOICE Polycarbonate and CR-39 (an allyl plastic) are the most widely used lens materials for safety prescription eyewear. CR-39 is lightweight and offers excellent optical clarity as well as durability. Polycarbonate is even lighter than CR-39 and provides significantly more impact resistance. However, polycarbonate is prone to easily scratching. Newer lightweight materials are now also available, including Trivex lenses. Your clinic will determine the best choice of lenses based on the available options approved by your employer, your work hazards and work environment as well as your prescription. The clinic staff are professionals at choosing the right lenses and will work to ensure the PROPER FIT for your eyewear. All Eyesafe™lenses meet CSA compliance standards.

LENS COATINGS

Lens coatings are available to protect you and your eyewear. Your job order will specify the type of coatings that are approved as well as any limits or restrictions. To avoid scratching your lenses, always wet before wiping. Scratch Resistance Coating: Available on all lenses, a scratch resistance coating protects your lenses by creating a stronger bond surface on the lens. While not 100% scratch-proof, the coating will prolong the life of your lenses by preventing minor scratches from wiping or small debris.

Ultra Violet Coating: An Ultraviolet (UV) coating provides protection from UV radiation that can potentially damage the structure of the eye. Some lenses already have a UV coating applied. Ask your clinic professional for details.

Anti-Reflective Coating: A thin coating that eliminates reflections and glare from the surface of

the lens. Anti-reflective coatings also improve light transmission through the lens for night driving and help reduce glare in bright sunlight.

Tints: Tinted lenses are widely used by workers exposed to bright sunshine for long periods of time as well as high intensity lighting tasks such as welding. Tinted lenses are not meant to be worn in low light conditions. If tints are an approved option by your employer, ask your clinic professional if tinted lenses are right for your work environment.

Photochromatics: Photochromatic lenses reduce the hassle of changing eyewear in differing light conditions. The lenses will automatically darken when exposed to specific types of light. Unlike tinted lenses, you cannot control how dark your lenses will get. When used in safety eyewear, it is important to understand that photochromatics take time to clear when the lenses are dark. The time delay will vary based on the darkness of the lens.
