1. How can I find the correct side shield for my frame?
The Uvex Rx Product Guide includes an easy cross-reference chart by shield number in the back of the guide.  If you know the specific frame(s) you can look up the frame by collection and it will give you the correct shield match up.  A cross-reference chart is also available online. Click here for the complete listing.

2. My employees complain that their side shields impair their side vision. Yet, side shields are mandatory in our plant. What can I do about this?
This is a very common complaint It’s true, most people don't like wearing side shields; however, it's been proven that shields do not significantly impair peripheral (side) vision. The following excerpts are from a study by the US Naval Weapons Center at China Lake, California, titled: “The Effects of Safety Glasses Side shields on Peripheral Vision . . . "

No statistically reliable degradation was found, etc. . . . ."

". . . . . visual resolution is not importantly degraded in the peripheral area by any of the side shields. Moreover, turning just the eyes to look through the shield foveally is unlikely since maximum eye movement is normally 35 degrees to left or right whereas most shields do not begin to appear until approximately 50 degrees or further."

3. Also about side shields . . .Forklift drivers complain that wearing side shields can cause them to have an accident because they can't see well. How can I handle this complaint? Not wearing shields isn't an option.
This specific issue was dealt with in a Canadian study and addressed by the Canadian Standard. Though this problem hasn't been formally addressed in the U.S., the resolution to the problem is appropriate regardless of location. Here's an excerpt from the study:
"The main complaints seem to come from lift truck operators who contend that they need peripheral vision to avoid accidents. The basis of the complaint is really not valid because the amount of visual acuity in the periphery is minimal even without side protection."

4. Is the standard called ANSI Z87.1-2010 or 2003?
The current standard, ANSI Z87.1-2010 was approved and went into effect on April 13, 2010. The ANSI Z87.1-2010 standard is significantly different from the 2003 standard. For the first time, the manufacturers of the complete device (laboratories) must test various lens retention systems. For more complete information about this part of the standard, please contact the Optical Laboratory Association at www.ola-labs.org.

For additional, general information regarding the ANSI Z87.1-2010 standard, we’ve created an overview, which is available in the “Resource” section of our website

5. Will all Uvex Rx frames now show the Z87.2+ marking?
Effective April 13, 2010, all safety frames manufactured must be marked with Z87-2+ if they meet the ANSI Z87.1-2010 standard.  Most manufacturers will need time to cycle through their existing inventories of older marked frames; therefore you can expect some delay during this changeover.  Current products that are marked according to the previous standard will be certified to the new standard.  For an up-to-date copy of this certification, you may contact our Customer Care team at 1.800.446.1802.

6. The standard states ANSI Z87.1-2010. Then you refer to Z87-2+. Which is it?
"ANSI Z87.1-2010" is the name of the standard. “Z87-2+” refers to the actual product markings for the frames and the lenses. The frame will be marked “Z87-2+”, indicating it passed testing with a 2.0mm representative test lens. The marking for the lenses shows a "+" mark after the manufacturer's logo

7. Does the standard explain how a manufacturing plant is supposed to decide which jobs require High Impact devices? Is there a guideline to follow?
The standard does not explain the responsibility of the employer.  It is the responsibility of the employer to perform an assessment of the facility and determine the protection required. Note that for some jobs, a face shield or goggle may be required OVER the safety glasses with side shields. If there are any questions, refer your customer to OSHA 29 CFR 1910.132 (for PPE) and OSHA 29 CFR 1910.133 for Eye and Face Protection. Visit www.osha.gov for copies of the regulations.

8. I have a lot of employees who wear prescription glasses. Some of them complain that the safety glasses I give them to wear over their regular glasses are uncomfortable. What should I do to get them to wear their safety glasses?
This is a question we are often asked. Because OSHA mandates that safety glasses are to be worn if there is danger of an eye injury, it is up to the employer to ensure the employees are wearing their safety glasses. If an employee must wear a prescription, the best way to make sure the glasses will be worn is to provide PRESCRIPTION SAFETY GLASSES. You may think this would cost you more, but actually the cost of implementing a prescription safety program is comparable to a program that provides only planos.

Your Uvex Rx Sales Representative will be happy to explain how you can administer a Prescription Safety Eyewear Program. For more information, call 800-446-1802 and press "2." Or, fill out our information request form and a representative will contact you soon.


9. Do you have side shields for dress frames?
No. A dress frame does not become a safety frame just by putting side shields on it. The frame will not meet the OSHA requirements (29 CFR 1910.133 for Eye and Face Protection), which incorporates the ANSI Z87 standard by reference (29 CFR 1910.6). The person wearing the frame could suffer an eye injury.

Safety frames are tested to meet the ANSI Z87.1 standards for impact resistance. In addition, Uvex Rx/Titmus side shields are designed, manufactured and tested for use on Uvex Rx/Titmus safety frames ONLY. Consequently, it is important to understand that the liability for performance of these side shields extends solely to Uvex Rx/Titmus frames specified for specific side shields and to no others.


10. Can I use other manufacturer's side shields on Uvex Rx frames?
Yes, if – and only if – the side shields have been tested on the specific frame and documented as passing the ANSI standard, otherwise no. (Please see Question 3 above for more details). Side shields are made to fit specific frames. This is even more important given the changes in the ANSI Z87.1-2010 standard (side shields must now provide greater lateral protection). Liability is also an important consideration, and applies as well to the use of Uvex Rx/Titmus shields on other manufacturer's frames.


11. Can I put dress (non-industrial) lenses into a safety frame?

Uvex Rx does not recommend using lenses that do not meet the Z87.1 standard for High Impact resistance in a safety frame. We realize our frames look good and are styled to have the appearance of a dress frame. However, keep in mind that if dress lenses are placed in a safety frame, the frame will not meet the Z87.1 standard for High Impact.

In addition, if an individual wearing the frame suffers an eye injury, the manufacturer of the prescription could be held liable. You will find few laboratories willing to fill such a prescription. We recommend using polycarbonate lenses that meet the ANSI Z87.1 standard for High Impact resistance in all safety frames.
