MCR Law OG1 OTG Safety Glasses — ANSI Z87.1+ Over-the-Glasses, Anti-Fog

The MCR Safety Law OG1 OTG is the simplest answer to the eyeglass-wearer's problem: an ANSI/ISEA Z87.1+ over-the-glasses frame that fits over most standard prescription eyeglasses, in two variants — Clear and Gray, both with UV Anti-Fog. The widened Law frame and extended temples clear your Rx frame underneath, so there's no removing PPE to read a label and no prescription safety-lens order.

Why the MCR Law OG1 OTG is the simple over-the-glasses pick

Eyeglass wearers on a jobsite face a bad choice without OTG: prescription safety lenses cost money and wait time, and contacts aren't for everyone. The Law OG1 removes the choice — Z87.1+ impact protection worn straight over the glasses you already have, with anti-fog on both tints so it stays on your face instead of your forehead. It's the value tier of MCR's OTG line, and for a lot of workers that's exactly enough. Our full OG1 OTG review rates it 4.3/5, and the safety glasses buyer's guide covers when OTG beats prescription lenses.

What the listing documents

From the published specs: ANSI/ISEA Z87.1+ high-impact rating; an over-the-glasses (OTG) Law frame with a widened cavity and extended temple arms that fit over most prescription frames; polycarbonate lenses; two variants — Clear and Gray, both with UV Anti-Fog coating; model OG110AF. As mcr safety law eyewear, the OG1 is the entry over the glasses safety glasses option, and with anti-fog standard it's a straightforward otg safety glasses anti fog choice.

Choosing between the two OG1 variants

It's a simple split: Clear with UV Anti-Fog for indoor work and Gray with UV Anti-Fog for outdoor glare over your clear prescription lenses. The clear-vs-smoke lens guide covers the tint decision, and since OTG frames fog more, the anti-fog guide and anti-fog collection explain why both variants ship coated.

OG1 vs the upgrade, and where MCR fits

Within MCR's OTG line, the OG1 is the entry option and the Klondike OG2 OTG is the upgrade — larger frame, hi-vis options, and MAX6/Dual Coat coatings. If you don't need those, the OG1 covers the OTG basics. MCR's standard-fit glasses run from the economy Klondike KD7 and simplified KD5 to the premium KD1, all in the broader MCR Safety glasses collection; the best safety glasses 2026 roundup places them against other brands.

Where it fits by wearer and crew orders

OTG suits eyeglass-wearing crews and visitor programs; for prescription wearers weighing fit, the women's fit guide and small-face guide cover smaller Rx frames underneath. Where the hazard exceeds impact — splash, dust, vapor — step to a sealed OTG goggle from the safety goggles collection or the broader eye protection collection.
