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.
Safety first: the OG1 OTG is impact-and-debris protection, not a sealed goggle — it is not rated against a chemical splash hazard, fine airborne dust, or vapor, which require sealed OTG goggles or a face shield per your hazard assessment. OTG fit is critical: verify it seats and closes over your specific prescription frame, since a frame too large to fit leaves gaps that defeat the protection. Choose eyewear against measured hazards using the when-do-you-need-safety-glasses guide.
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. Compare the wider OTG field in the over-the-glasses collection, including the Uvex Astro OTG.
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. For a fuller comparison of clear indoor lenses, the clear-lens collection covers standard-fit alternatives.

Reading the Z87 marking, and what it does not cover
Protective eyewear in the US is built to ANSI/ISEA Z87.1, and OSHA 1910.133 requires eye protection that meets it. The marking on the frame is the specification, and the important distinction is a single character: Z87 is basic impact, Z87+ is high impact — tested with a quarter-inch steel ball at 150 ft/s for spectacles. If the work throws anything, Z87+ is the line.
The suffixes narrow it further: D3 is splash and droplet, D4 dust, D5 fine dust. These matter because a spectacle cannot earn D3 — droplet protection needs a sealed goggle. Safety glasses are impact protection, not chemical splash protection, however wraparound the lens looks, and substituting one for the other is a common and consequential error.
A face shield is also secondary protection under 1910.133: it is worn over primary eye protection, never instead of it. And tint is not shade — a dark lens without a stated IR/UV shade number offers no rated protection against radiant energy.
Frequently asked questions
What is the MCR Safety Law OG1 OTG?
The entry-level over-the-glasses (OTG) safety glass in MCR's line, rated ANSI/ISEA Z87.1+ high-impact and built to fit over most standard prescription eyeglass frames. It comes in two variants - Clear and Gray, both with UV Anti-Fog coating - on the widened Law frame.
What does OTG (over-the-glasses) mean?
OTG frames are sized to fit over your own prescription eyeglasses, giving Z87.1+ impact protection without buying prescription safety lenses or switching to contacts. The Law frame's widened cavity and extended temples accommodate most Rx frames underneath.
Who is the OG1 built for?
Workers who wear prescription eyeglasses and need impact protection over them - so there's no removing PPE to read labels or see fine detail, and no cost or lead time for prescription safety lenses. It's the simple, universal OTG option.
Why do both variants have anti-fog?
OTG designs trap warm air between the safety lens and your prescription lens, which amplifies fogging. MCR ships both the clear and gray Law OG1 with UV Anti-Fog because fog control isn't optional on an OTG - it's the difference between wearing it and pushing it up.
Is it ANSI Z87.1+ rated?
Yes - it carries the ANSI/ISEA Z87.1+ high-impact rating (the '+' marks passing the high-velocity and high-mass impact tests), so it meets the requirement for most industrial eye hazards, worn over your glasses.
OG1 or the Klondike OG2 OTG?
The OG1 is the entry option: two anti-fog variants on the Law frame. The OG2 upgrades to the larger Klondike frame, adds hi-vis frame options, and offers MAX6 and Dual Coat coatings. If you need hi-vis or premium anti-fog, step to the OG2; if you need a simple OTG, the OG1 delivers.
Will it fit over any prescription frame?
It fits most standard prescription frames, but very large or wraparound Rx frames may not seat well. Check the fit over your specific glasses - an OTG that doesn't close properly leaves gaps that defeat the protection.
Is it enough, or do I need goggles?
The OG1 OTG protects against impact and debris from the front and sides. It is not a sealed goggle - it does not seal against a chemical splash hazard, fine dust, or vapor, which need sealed OTG goggles or a face shield. Match the eyewear to your hazard.
Does it block UV?
Yes - the UV Anti-Fog coating and polycarbonate lens block UV, worn over your clear prescription lenses. That covers the UV exposure of general-industry and outdoor tasks.
How does the gray tint work over clear Rx lenses?
The gray OTG lens sits outside your clear prescription lens, tinting the whole view for outdoor glare - like putting sunglasses over your glasses, but Z87.1+ rated. Use clear indoors and gray outside.
How do I care for the lenses?
Rinse grit before wiping and use a microfiber or lens-safe cloth on both the OTG lens and your glasses underneath; harsh cleaners strip the anti-fog coating. Retire the OTG lens once scratches enter your line of sight.

Comfortable, Clear, and Reliable Over-Glasses Protection
Comfortable, Clear, and Reliable Over-Glasses ProtectionThese MCR Safety OG110AF glasses are a great solution if you wear prescription eyewear but still need solid eye protection. They fit comfortably over my regular glasses without feeling too bulky or pressing against the frames. The clear polycarbonate lenses give good visibility, and the anti-fog coating works well—I haven’t had issues with them fogging up, even in warmer conditions.I also appreciate that they’re lightweight but still feel sturdy. The UV protection is a bonus if you’re using them outdoors, and the scratch-resistant coating helps keep the lenses clear after repeated use. They don’t look stylish, but that’s not the point—these are about function, and they do the job well.The only thing to keep in mind is that they’re fairly large, so if you have smaller glasses or a narrow face, they may feel oversized.Bottom line: A dependable, comfortable pair of safety glasses designed to fit over prescription eyewear. They deliver clear vision, solid protection, and are a smart buy for anyone who needs reliable eye coverage on the job or for home projects.

Best OTG Safety Glasses
Excelent Over The Glasses (OTG) safety glasses. I have tried 6 different pair of OTG safety glasses from Amazon. This is by far the best of all. They fit my glasses well and don't produce a lot of shiny reflections like other brands. The ear piece does not wrap over the ear. It kind of clamps on the side of the head above my glasses ear pieces. I also wear behind the ear hearing aids so normal safety glasses that wrap behind the ear can get difficult to keep in place and hurt the ears. Not these. They are very comfortable. The first time I wore them I had them on for 6 or 7 hours straight and never really noticed them. I am usually taking my safety glasses off frequently to get a break from them. I highly recommend these OTG Safety Glasses! Best I've every worn in more than 20 years of wearing OTG safety glasses.

The're very OK. Contact points on temples are small = fatigue/hurt. Other + & - too.
Well... these are OK. Temples are very curved.. can not wear ear protection. Temple pads on the end are small and fatigue/hurt have a short use. Very OK dark gray and no distortion for an inexpensive pair. Frame hangs on your glasses... no contact with bridge or face. Temples adjust up/down (not in/out) to adjust the pitch of the frames... nice.

We can have affordable non prescription safety glasses now!
These fit over my extremely wide frames. My glasses are roughly 5.75 inches wide. Yeah, too wide for over glasses frames that aren’t extra large. These fit! They do sit a bit far from my eyes since my frames are maxing them out. However, I do a lot of crafting with glass and these are a must have. The others I tried all had to be returned.I’ve already recommended these to my friend who loves cats-frames as well! We can have affordable non prescription safety glasses now!These are very comfortable. Light weight and rest comfortably on my frames. Safety first! Unless you can’t wear safety glasses because your prescription glasses are too big. That’s no longer an excuse! I ordered another pair!

I'm impressed!
I'm Impressed! These fit well over my sunglasses or regulars prescription for gardening/pruning, etc. anything where things fly at my face. They worked well when a limb dropped on me. I've already broke a pair of expensive prescription sunglasses (that at least protected my eye from injury) when my edger threw up a good sized rock. Now my glasses are protected too. The low price belies how well these are made with a clean finish, no snags. FYI, I'm a female with a small face and nose. These would fit someone with a larger face and larger glasses, at least the average male, but stay on me just fine. I wear them with a leash, just in case. For heavy protection or fumes, these would NOT work but are fine for light labor.

Good protective eye wear!
I am happy to have protective eye wear during this pandemic. I bought these in the beginning of COVID 19 virus 🦠 pandemic thinking that if the virus could enter my mouth and nose, why not the pupils of my eyes. They fit over my eye glasses. The protective frames have a hinge on each arm so I can pivot the arms of the frame downward for a tighter fit but I notice that the glasses still slip off if I bend down. They are plastic and can be washed after every usage with simple soap and water. The eye glasses themselves are NOT scratch resistant so be careful not to drop them or store them next to sharp objects. Also, the protective wear are sold without a case so I return them to their original plastic bag after each wearing/cleaning and usage. Overall, the product does what I want it to do! I and my family who wear them along with masks and gloves are healthy still! Thus, I would recommend these protective frames. PS- these protective eye frames can be worn doing other chores as well ...
