Eye injuries are costly.

Not only to your bottom line but to your company’s most important strength: your staff.

Over the years we have gotten a ton of questions about prescription safety eyewear.

So we decided to answer the top questions about your eyewear options and how to improve safety and compliance while on the job.

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.

To know if your personal glasses meet CSA requirements, look for the following:

PPE026b

  • The frame will be marked with a Z94.3 (CSA) mark on the inside of the arm.
  • The manufacturer’s monogram needs to be on the prescription lens. You’ll find it in the top corner of the lens. (We use a ‘P,’ others use an ‘S’ for safety or the first letter of the company name).
  • Side shields must be permanently affixed to the frame.

These are the visible requirements that indicate other tests were conducted based on CSA standards and that the manufacturer understands those requirements.

Other tests include impact, ignition and flame resistance, frame and side shield coverage, lens type and thickness.

 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.

Approved safety frames must now have permanent side shield protection as of December 1, 2007.

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.
