OnGuard OG 141 Prescription Safety Glasses

The plain-clothes rated frame

Not every rated prescription pair needs to look like PPE. The OG 141 is a titanium frame with no side shields and a conventional silhouette, so it reads as ordinary eyewear while still carrying both the US ANSI Z87.1 and Canadian CSA Z94.3 impact ratings. It is the entry point of the OnGuard titanium range.

No side shields — check your requirement first

The OG 141 ships without side shields and none are fitted. If your site or safety program requires lateral protection, choose a shielded OnGuard model instead — the OG 109 comes with EZ Shields fitted, and the OG 080 includes removable shields.

Prescription lenses for the work environment

Lenses are glazed to your prescription in polycarbonate, the impact-resistant material that holds the Z87.1 rating. Single-vision, bifocal and progressive prescriptions are supported. Anti-fog, anti-reflective and anti-scratch coatings are all available.

Fit

Eye size 50, bridge 21, temple 145. The unusually wide 21 mm bridge makes this a good option for higher or wider nose bridges where a standard 17–18 mm bridge sits too low.
