The Klein Tools 60171 Semi Frame Safety Glasses are plain clear eyewear for tradespeople who want certified impact protection. You get a 2-pack, so there is a spare for the truck. On paper, they are a solid everyday pair.
Impact rating comes firstand these meet ANSI Z87.1+, CSA Z94.3 and MIL-PRF-32432A. The scratch resistant lenses and the anti-fog coating Klein says won’t wear off matter when you work in a dust maskand the rubber nose piece and temples are meant to keep the fit snug.
Quick verdict: A no-frills, standards-rated clear pair for daily jobsite wear, judged on the listed specs.
- Best for: Techs who want clear lenses, anti-fog and a spare pair.
- Skip it if: You want a hard case included, since it is sold separately.
- Key spec: ANSI Z87.1+ impact rating with UV protection blocking 99.9% of UV rays.
Klein Tools 60171 Specs and What Comes in the 2-Pack
The spec that matters most is impact protection. This Klein pair meets ANSI Z87.1+, CSA Z94.3 and MIL-PRF-32432A standards. On a jobsite that is the first thing I check, before color or style. Everything else is comfort and convenience.
- Lens: clear, scratch resistant, specially treated for demanding jobsites
- Anti-fog: coating Klein says won’t wear off, built to work with dust masks
- UV: tested to ANSI Z87.1 U6, blocks 99.9% of harmful UV rays
- Fit: low profile narrow lens with a rubber nose piece and rubber temples
- Build: lightweight, flexible materials in a semi frame design
Clear lenses make sense for indoor work like attics, mechanical rooms and crawlspaces where you don’t want a tint. The anti-fog claim is the one I’d watch, since fogging under a mask is a common reason guys pull their glasses off. Rubber on the nose and temples should help them stay put when you’re sweating or looking down into a unit.
The 2-pack gives you a spare pair, so one can stay in the truck and one in the bag. A hard case (Cat. No. 60176) and a breakaway lanyard (Cat. No. 60177) are sold separately.
How Clear and Scratch Resistant Is the Clear Lens?
The lenses are clear and treated for scratch resistance, which Klein says adds durability for demanding jobsites. That treatment matters more than most buyers think. Scratches are usually what retire a pair of cheap safety glasses, long before anything breaks.
Scratch resistant does not mean scratch proof. The description gives no hardness rating or test data, so I treat it as a step up from a bare lens and nothing more. On HVAC and refrigeration jobs, glasses get tossed in bags, set on sheet metal and wiped with a dirty shirt. Grit does most of the damage in those situations. A clear lens with no tint is also the right call for attics, crawlspaces and dim mechanical rooms, where you need every bit of available light.
The 2-pack helps here. Keep one pair in the truck and one in your bagand a scratched pair never has to stay on your face. Klein sells an optional hard case (Cat. No. 60176) separatelyand a case is the simplest way to keep grit off the lenses. Blow off or rinse the dust before you wipeand the coating will last longer.
Build Quality and Jobsite Durability of the Semi Frame Design
The most useful durability fact is the impact rating. The lenses meet ANSI Z87.1+, CSA Z94.3 and MIL-PRF-32432A, so check for those standards on the label before you trust any pair around drilling, cutting or flying debris. Klein also lists a U6 UV rating under ANSI Z87.1 that blocks 99.9% of harmful UV rays.
Scratches are what usually retire a pair of safety glasses. They get tossed in a tool bag, set on a rooftop unit and wiped with a dirty shirt. Klein says these clear lenses are specially treated to resist scratching, which is the right feature for that kind of treatment. The anti-fog coating is listed as one that won’t wear offand Klein says it holds up when you wear a dust mask. I can’t confirm that claim myself, but it matters, because fogged lenses make people pull their glasses off.
The semi frame is built from lightweight, flexible materials, with a rubber nose piece and rubber temples. On glasses in this class, the parts that loosen or wear out first are usually the temples and nose pad, so grip and flex are worth looking at. The lens is low profile and narrow. That keeps the frame small, but it also means less coverage than a wraparound style. Since this comes as a 2-pack, you can keep a spare in the truck. A hard case and a breakaway lanyard are sold separately.
Do Klein Safety Glasses Fit With Hard Hats and Earmuffs?
Klein does not list hard hat or earmuff compatibility in the product details, so I can’t promise a fit. What it does list is a low profile narrow lens, lightweight flexible materials and a rubber nose piece and temples. Those are the features that decide whether safety glasses get along with other gear.
Here is what I would check when they arrive:
- Temple thickness: Flexible rubber temples may lie flatter under an earmuff cup, but check for a gap in the seal that lets noise through.
- Lens clearance: A narrow lens leaves more room near a hard hat brim. Make sure the hat does not push the frame down your nose.
- Nose piece grip: Tightening a hat suspension can shift your glasses. Check that the rubber holds them in place.
- Dust mask seal: The anti-fog coating is described as holding up with dust masks. Check the mask still seals at the bridge of your nose.
Hard hats and earmuffs vary a lot between brands, so test with your own setup. Look up, bend over and turn your head the way you would on an overhead job. If the glasses stay put and the muff seals clean, you are good. If not, the 2-pack at least gives you a spare to keep in the truck.
Semi Frame vs Full Frame Safety Glasses for Daily Wear
For all-day wear, semi frame is the style I lean toward. Less frame around the lens means less weight and bulk on your face over a long shift. This Klein pair has a low profile narrow lens, plus a rubber nose piece and rubber temples for a face-conforming fit and sure grip. That grip matters when you are sweating in an attic or bent over a condenser.
Full frame glasses surround the whole lens, which usually feels bulkier. Semi frame trades some of that for a lighter pair you stop noticing. Check the rating before you pick either style. This pair meets ANSI Z87.1+, CSA Z94.3 and MIL-PRF-32432A for impact resistance, so the open edge is not a sign of weak protection on paper.
Here is what I would check on any pair you plan to wear daily:
- Fog control: the anti-fog coating is described as lasting, with clear vision when worn with a dust mask.
- Scratch resistance: treated clear lenses hold up better on a rough jobsite.
- UV rating: tested to ANSI Z87.1 U6, blocking 99.9% of harmful UV rays.
- Spare pair: this comes as a 2-pack, so one can stay in the truck.
Best Jobs and Users for a Semi Frame 2-Pack
These fit best on dusty, close-quarters work where you wear a mask. The anti-fog coating is listed as one that won’t wear offand the description says it keeps vision clear with dust masks. That matters when you are cutting, drilling or crawling through an attic with a respirator pushing breath up behind the lenses.
Impact ratings cover ANSI Z87.1+, CSA Z94.3 and MIL-PRF-32432A, so they suit flying debris from drilling, fastening and grinding. The clear lenses also block 99.9% of UV raysand the scratch resistant treatment helps when the glasses ride around in a bag with other tools. Clear lenses work well in dim crawlspaces and mechanical rooms. They are not the pick for bright sun, since there is no tint.
- Good fit: techs, electricians and installers who wear dust masks most of the day.
- Good fit: anyone who wants a low profile narrow lens that sits close to the face, with rubber on the nose piece and temples for grip.
- Good fit: crews that want a spare pair, since the 2-pack covers the truck and the tool bag.
- Look elsewhere: heavy dust or splash work where you want a sealed goggle instead of a semi frame.

Do Klein Tools 60171 safety glasses fog up?
They are designed not to, since Klein says the anti-fog coating won’t wear off. The coating is meant to keep vision clear even when you wear a dust mask. Fogging is a common reason guys pull glasses off in attics and tight mechanical rooms. No coating is perfect, so judge it in your own conditions.
Does the Klein Tools 60171 come with a case or lanyard?
No, the 60171 is a 2-pack of glasses only. Klein sells the Hard Case (Cat. No. 60176) and the Breakaway Lanyard (Cat. No. 60177) separately. A case helps keep lenses from getting scratched in a tool bag. Order them with the glasses if you want them.
Are Klein Tools 60171 safety glasses comfortable for all day wear?
They are built for long-term comfort, according to Klein, using lightweight and flexible materials. The nose piece and temples are rubber for a face conforming fit and sure grip. The lens is a low profile narrow design. Fit is personal, so I can’t promise they suit your face
Final Verdict
The Klein Tools 60171 is a plain pair of clear safety glassesand the 2-pack is a practical touch. Keep one in the truck and one in the toolbox. The ratings are what matter: ANSI Z87.1+, CSA Z94.3 and MIL-PRF-32432A for impact, plus U6 UV protection that blocks 99.9% of UV rays. The anti-fog coating is listed as one that won’t wear off, which helps when you wear a dust mask. How long that holds up is something only time on the job will show.
This is a solid buy for a working pro or serious DIYer who wants rated eye protection without fuss. A homeowner doing weekend projects will be fine with it too. Look elsewhere if you want wider coverage, since the lens is a low profile narrow design. Skip it for bright outdoor work too, because these are clear lenses. The hard case and lanyard are sold separately.
