The MCR Safety Klondike KD3 brings a feature most economy wraparounds skip: a built-in Clear Bifocal +1.0 reader option, alongside clear, gray, light blue, and indoor/outdoor tints with anti-fog choices — all on the ANSI/ISEA Z87.1+ wide Klondike frame. For close-up workers who'd otherwise juggle readers, the bifocal segment is the reason to pick the KD3 over its siblings.

Why the MCR Klondike KD3 adds a bifocal to the wide wrap
Reading fine print in safety glasses is a real problem: gauges, labels, and small fasteners all sit at reading distance, and swapping to separate readers means a moment with no eye protection. The KD3's bifocal option puts a magnified segment right in the Z87.1+ lens, so close-up work happens without a gear change. Add indoor/outdoor and anti-fog variants on the same wide Klondike frame, and it covers a wider set of needs than a plain economy glass. Our full KD3 review rates it 4.4/5, and the safety glasses buyer's guide covers where a bifocal frame fits.
Safety first: the KD3 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 goggles or a face shield per your hazard assessment. Pick the bifocal power that matches your reading need, and match the tint to the light — a gray or I/O lens indoors dims your view of hazards. And a glass only protects while it seals: verify the wrap seats past the temple. 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; a wide Klondike wraparound polycarbonate frame; tints in Clear, Gray, Light Blue, and Indoor/Outdoor with anti-fog options; a Clear Bifocal +1.0 reader variant; not OTG; model KD310. As mcr safety klondike eyewear, the KD3's bifocal makes it one of the few bifocal wrap safety glasses in the economy tier, and its I/O lens puts it among practical indoor outdoor wrap safety glasses.
Choosing your KD3 variant
Match the option to the task: Clear or Clear Anti-Fog for indoor work from the clear-lens collection, Gray for outdoor glare (see the clear-vs-smoke guide), Indoor/Outdoor for shifting light from the I/O collection, and the Bifocal +1.0 for close-up reading — the safety reading glasses collection covers the reader category. Anti-fog variants pair with the anti-fog guide and anti-fog collection.
Where the KD3 sits in the Klondike family
The Klondike line scales by feature: this KD3 adds the bifocal and I/O options, the KD7 maximizes tint selection, the KD5 simplifies to two variants, and the premium KD1 brings Amber and Silver Mirror. The KD7R adds ratchet temples; prescription wearers take an over-the-glasses frame from the OTG collection. The full MCR Safety glasses collection and the best safety glasses 2026 roundup place the KD3 against other brands.
Where it fits by job and crew orders
The bifocal option makes the KD3 a fit for inspection, assembly, and maintenance work with fine print — the manufacturing and mechanics guides rank frames by task, and smaller-faced wearers should check the small-face guide. Browse the broader eye protection collection for goggles and face shields where the hazard exceeds what glasses cover.

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 Klondike KD3?
A wide-wraparound ANSI/ISEA Z87.1+ high-impact polycarbonate safety glass in the Klondike line, offered in clear, gray, light blue, and indoor/outdoor tints with anti-fog options - plus a Clear Bifocal +1.0 reader variant that most economy safety glasses don't include.
What makes the KD3 different from the other Klondikes?
Its built-in +1.0 bifocal reader option and indoor/outdoor tint on the wide Klondike frame. Where the KD5 and KD7 focus on standard tints, the KD3 adds a magnified reading segment for close-up work without swapping to separate readers.
What is the +1.0 bifocal option for?
A magnified reading segment at the bottom of the lens so you can read gauges, labels, and fine print without switching to reading glasses - all while keeping ANSI Z87.1+ protection. The +1.0 is a light magnification suited to mild close-up needs.
What is the indoor/outdoor tint for?
An I/O lens is a light mirror tint that cuts outdoor glare without going fully dark, so it stays usable when you step back inside - handy for workers who move between a bright yard and a shop through the day.
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 out of the box.
What tints and coatings does it come in?
Clear, gray, light blue, and indoor/outdoor tints, with anti-fog coating options on several, plus the Clear Bifocal +1.0 variant. Match the tint to your light and the coating (anti-fog vs standard) to your humidity.
What does the wide Klondike wrap do?
It extends coverage past the brow and temple to reduce lateral particle ingress that narrow frames let through - meaningful protection in general industry and construction where debris comes from angles.
Is it over-the-glasses (OTG)?
No - the KD3 is not an OTG frame. Prescription-glasses wearers should look at MCR's OTG models like the Klondike OG2, or use the KD3's bifocal option if a reading segment is all they need.
Is it enough, or do I need goggles?
The KD3 protects against impact and debris from the front and sides. It does not seal against a chemical splash hazard, fine dust, or vapor - those need sealed goggles or a face shield. Match the eyewear to your hazard assessment.
Which variant should I choose?
Clear or clear anti-fog for indoor work, gray for outdoor glare, indoor/outdoor for shifting light, and the Clear Bifocal +1.0 if you read fine print up close. Our lens guides walk the tint tradeoffs.
How do I care for the lenses?
Rinse grit before wiping and use a microfiber or lens-safe cloth; harsh cleaners strip anti-fog coatings. Retire a lens once scratches enter your line of sight - a scratched bifocal segment is doubly distracting.
How do I order for a crew?

Good glasses
I like these glasses because I can adjust the ear pieces to fit so much better. I'll buy these again.

... recall the brand names) but these are the most comfortable that I've found
I've tried several different types of safety glasses down through the years (don't recall the brand names) but these are the most comfortable that I've found. Some glasses are comfortable but give me headaches after a period of time, but these never have and they are good quality. These fit comfortably on the bridge of your nose and they don't cut your ears like some of the cheaper brands. For the price Crews Klondike's are hard to beat.

Best adjustable fit around
The adjustable tilt keeps the glasses off my cheeks and provides better eye protection. Regular off the shelf sunglasses/safety glasses leave too much eye area unprotected, these are more like goggles in covering my eyes. Just bought my 3rd pair and one for a friend.

Head squeezers
These were mentioned on Frank Spear's blog for use as patient safety glasses to increase patient comfort by protecting eyes from the rare flying piece of amalgam or porcelain as well as the bright dental light. They accomplish that well enough. They are uncomfortable to wear.

They irritate the bridge of my nose.
Decent-looking, light-weight design with various ways to adjust the arms and the flexible bridge, but they irritate my nose.
