Description
ANSI Z87.1 + CSA Z94.3 dual-certified · Integrated side shields · Available in Small / Medium / Large
The OG225S is the dual-cert industrial frame that crews actually keep in the program. ANSI Z87.1 for the US side, CSA Z94.3 for Canadian crews, integrated side shields that don’t pop loose, and three frame sizes from one SKU so the safety officer doesn’t have to stock three frame catalogs. Cut for prescription, FSA/HSA eligible, in stock.
OnGuard’s industrial line exists specifically because the US and Canadian impact-rating standards diverge in detail even when they look the same on paper. ANSI Z87.1 and CSA Z94.3 each have their own ball-drop velocities, their own permitted shield architectures, and their own marking conventions. The OG225S clears both — same frame, same lens, dual-marked. For contractors moving crews across the border or for safety officers buying for binational operations, that single-SKU dual cert is the entire reason this frame exists.
On removable-shield frames, the cert holds only when the shields are seated correctly. In the field, that’s a problem: shields get knocked loose, stripped from the frame during cleaning, or swapped between frames by mistake. The OG225S sidesteps that whole class of failure mode by molding the shields into the frame itself. The cert is permanent because the geometry is permanent. The trade-off is that the OG225S is a dedicated-shift frame; the OG220S in the same OnGuard line is the equivalent product with removable shields if you need a frame that doubles as off-shift eyewear.
The S / M / L sizing on the OG225S is one of the most underrated procurement features in the industrial-Rx category. Most safety frames are sold in one size and the safety officer compensates by buying a second frame model for outliers. The OG225S covers small-PD wearers (under 60 mm), the standard middle, and broad-temple wearers (above 68 mm) from a single product page. That means stocking one SKU instead of two or three frame models — fewer line items, less inventory friction, and a single fitting reference.

Product Q&A
Frequently asked Questions about OnGuard OG225S ANSI Rated Safety Prescription Glasses
Why does this frame carry both ANSI Z87.1 and CSA Z94.3?
Because OnGuard sells into both US and Canadian industrial markets, and the dual certification means one frame works on both sides of the border. ANSI Z87.1 is the US impact spec (the 50-inch ball drop plus the high-velocity test on Z87+ models); CSA Z94.3 is the Canadian equivalent, with similar but not identical impact criteria. If you’re a contractor running crews in both countries, the dual mark on the OG225S frame removes the procurement headache.
Three frame sizes — how do I pick S, M, or L?
Most adults wear the medium. The OG225S small fits closer faces and PD measurements roughly under 60 mm — common in women’s fitting and youth-adjacent sizing. The large fits PDs above 68 mm and broader temple-to-temple measurements; common for higher-volume PPE programs that issue across diverse crews. If you have an existing pair of glasses you like the fit of, measure the temple-to-temple width on the bridge and match within 4 mm.
How are the side shields attached — can I take them off?
Integrated, not removable. The OG225S is a permanent-shield design — the shields are part of the frame mold, not an after-market clip-on. That’s actually why the dual cert sticks: removable shields can pop loose during impact and disqualify the frame from CSA Z94.3 for certain configurations. If you need a frame where the shields come off for off-shift wear, look at the OnGuard OG220S; if you want the shields built-in for guaranteed compliance, the OG225S is the right pick.
What prescription range does it accept?
Wide. Polycarbonate covers single-vision Rx to roughly +/-6.00 sphere with cylinder up to -3.00, which fits over 90% of working-adult prescriptions. Trivex is available for buyers who want lighter weight and a higher Abbe number (less chromatic distortion). High-index 1.67 is supported for stronger prescriptions where edge thickness would otherwise look chunky against the integrated-shield housing.
