• Jonathan McCallumYour Top Safety Prescription Eyewear Questions Answered!

    Eye and vision-related injuries are costly not only for your bottom line, but for your company’s most valuable asset: your employees. Since we’ve been protecting workers from on the job eye injuries for decades, we come across a lot of questions about not just protective eyewear, but about safety prescription eyewear.

    Check out the answers to your top questions.

    How do I know if my personal glasses meet the safety standards for work?

    All safety eyewear must be approved and compliant with the CSA Standard Z94.3.

    Frames and lenses must pass rigorous testing before they are approved for use as safety eyewear. All safety frames must bear either a Z87.1 or Z94.3 mark on the inside of each temple.

    Prescription safety lenses must bear the manufacturer’s logo monogrammed on the top temporal corner of each lens.

    Will the use of clip-on side shields make my personal glasses safe for work?

    No. After market clip-on side shield protection is not compliant with CSA guidelines. Effective Dec. 1st, 2007 approved safety frames must now have permanent side shield protection.

    Are hardened glass lenses safe to use on the job?

    No. Approved safety lens materials are CR39 plastic, polycarbonate and trivex. Glass lenses do not meet CSA lens impact requirements and are therefore not compliant.
