The Spy Cyrus is a square, thick-sided sunglass that doesn't try to blend in. Spy built it for everyday wear, gave it the Happy Lens tint the brand is known for, and offered it in a polarized version for people who spend their weekends near water or their commutes squinting into a windshield. It sells well for a simple reason: it looks like a fashion frame and is built like a sport frame. What it isn't, and this matters to a lot of the people who land on this page from a jobsite search, is a safety glass. That distinction decides whether the Cyrus is the right buy for you or whether you want one of its Z87-rated cousins.
What the Spy Cyrus actually is
The frame is Grilamid, a nylon-based material Spy uses across its lifestyle line because it stays light and flexes instead of snapping. The hinges are 5-barrel, which is the detail you notice two summers in when a cheaper frame has started to wobble at the temple. The lenses are Spy's ARC polycarbonate, tapered to follow the curve of the eye so the edges of your view don't warp.
Spy lists the Cyrus at 58-17-145: a 58 mm lens, a 17 mm bridge, and 145 mm temples. On our listing that works out to a 145 mm frame width, a 56 mm frame height, and 124 mm hinge to hinge. That 56 mm height is the number to pay attention to. It is a tall lens, which means more coverage from brow to cheek and a frame that reads big on a narrow face.
Spy rates the fit medium to large and recommends it for round and oval face shapes. If you have a long, narrow face, the Cyrus can look like you borrowed it. If you have a round face, the hard square lines do what square frames are supposed to do and add some structure.
The three lens options
The Spy Cyrus comes in three lens configurations on our site.
HD Plus Grey Green Polar. This is the polarized version and the one most buyers should start with. Grey green is a neutral tint that keeps colors close to true, and the polarizing filter cuts the flat glare that bounces off water, wet pavement, and car hoods. Spy layers and seals the filter inside the lens rather than coating it on the surface, which is what keeps it from hazing or peeling over a few seasons of use.
Happy Gray Green. The same base tint with Spy's Happy Lens treatment and no polarizer. Spy says Happy Lens lets through the long-wave blue light it associates with mood and alertness while blocking the short-wave blue, and that it boosts color and contrast. We cover how that works, and what is and isn't proven about it, in our Spy Happy Lens explainer. Skipping the polarizer makes sense if you read phone or dashboard screens a lot, since polarized lenses can black out some displays at certain angles.
Happy Bronze Blue Spectra. A bronze base with a blue mirror on the outside. Bronze warms the view and sharpens contrast in flat or mixed light, and the mirror knocks down a bit more brightness while giving the frame its louder look. If you want to know what a mirror does and doesn't add over polarization, our mirrored vs polarized breakdown walks through it.
Availability shifts by lens. Check the product page for which versions are shipping right now before you settle on one.
The Cyrus is a great pair of sunglasses. It is not a pair of safety glasses, and nothing printed on the frame says otherwise.
Is the Spy Cyrus Z87 rated?
No. The Cyrus carries no ANSI Z87.1 marking, and Spy doesn't market it as a safety frame. That's normal for a lifestyle sunglass. Z87 is the impact standard for occupational eye protection, and a frame only meets it when it has been tested and is stamped with the mark on the frame and lens. If your employer, your shop, or your site requires Z87, the Cyrus won't satisfy it no matter how sturdy it feels in hand. OSHA's eye and face protection rule, 29 CFR 1910.133, points employers to that ANSI standard.
The difference between a sunglass standard and a safety standard trips up a lot of buyers. We go through it in ANSI Z80.3 vs Z87, explained, and our Heat Wave Visual vs Spy Optic comparison covers which Spy frames are rated and which are not.
If you like the Cyrus but need Z87
Spy makes rated frames with the same lens story, and they are the honest answer for anyone who wants the Spy look on the clock.
The Spy Region XL is the closest in spirit. It is a full-size frame with more coverage than a standard sunglass but less wrap than a sport shield, Spy rates it to ANSI Z87.1, and it comes with Happy Boost lenses including a polarized option. It fits medium to large, much like the Cyrus.
The Spy Rebar goes further toward the job. It is a wraparound with Spy's Scoop venting to fight fog, rubber nose pads and temple tips that hold through sweat, and a Z87+ marking for high-mass impact. It fits large to extra large, so it is the better choice for bigger heads.

Can you get the Cyrus in prescription?
Yes, as an eyeglass. Spy makes a Cyrus optical frame, the Spy Cyrus Optical 58, which takes prescription lenses. It is sold as a frame only, and any licensed optician can fit lenses to it. Like the sunglass, it isn't a safety frame. If you need prescription eyewear that is also Z87 rated for work, that is a different product, and our guide to ordering prescription safety glasses covers how that works.
Who the Cyrus is for
Buy the Cyrus if you want a square sunglass with real presence, you'll wear it driving, fishing off a dock, or at a weekend game, and you don't need it to pass a safety inspection. Pick the polarized version if water and road glare are your main enemy. Pick a Happy Lens version without polarization if you live on your phone or fly a drone and need screens to stay readable.
Skip it if you need Z87 for work, if you have a narrow face that a 58 mm square will swamp, or if you want a frame that wraps around the side of your head to block light and debris. In any of those cases, one of the rated Spy frames above will serve you better.
