Eye and vision-related injuries are costly not only for your bottom line, but for your company’s most valuable asset: your employees. Over the years we have gotten a ton of questions about not only protective eyewear, but prescription safety eyewear. What are your options and how do you know whether you’re staying safe and compliant while on the job?

Keep reading to learn the answers to our 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.

How do I know if my Prescription Glasses meet CSA/ANSI requirements?PPE026b

Look for are the following distinctions:

  • The frame must be marked with a Z87.1 (ANSI) or Z94.3 (CSA) mark on the inside of the arm.
  • Each prescription lens must be distinctly marked in a permanent and legible manner with the manufacturer’s monogram, placed so that interference with the wearer’s vision is minimal (usually in the top outside corners of each lens). For Levitt-Safety eyewear we use a “P”. Others may use an “S” for Safety or the first letter of the company name.
  • In the case of CSA, side shields must be permanently affixed to the frame.
  • The above requirements are the visible ones that indicate that other tests have been conducted (impact, ignition and flame resistance, frame & side shield coverage, lens type and thicknesses) per the CSA or ANSI standard and that the manufacturer understands those requirements.

 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.
