Knockaround Sunglasses Review

Knockaround's pitch is a specific-looking, genuinely UV400 pair for almost no money, with endless frame and lens color combinations. We break down the classic Premiums, the sportier Fast Lanes and the rounded Paso Robles — and flag the one SKU detail that trips buyers up.

By Stephen V.Last updated How we pick

Knockaround’s whole idea is to let you build a specific-looking pair of sunglasses for almost no money. Pick a frame shape, pick a frame color, pick a lens color — the combinations run into the hundreds — and the result costs about what you’d spend on lunch. Crucially, the lenses clear the one non-negotiable spec: they’re rated UV400, which blocks 100% of UVA and UVB. That’s the part most sub-$25 brands quietly skip, and Knockaround doesn’t.

There is one catch worth stating up front, because it’s the thing buyers get wrong: not every Knockaround is polarized. Popular models like the Premiums, Fast Lanes and Paso Robles offer polarized versions, but some trims and colorways ship non-polarized to hit the lowest price. UV protection is standard; polarization is an option you have to select. Check the specific SKU before you check out.

We haven’t stress-tested every colorway. This is a spec-first read of Knockaround’s published lens specs plus honest buyer-fit reasoning. Below are the three models worth your money: the classic Premiums, the sportier Fast Lanes, and the rounded Paso Robles.

Are Knockaround sunglasses worth it?

As a cheap, customizable everyday pair, yes — provided you buy with your eyes open on two points: which lens spec you’re actually getting, and the tier of build you should expect for the money. Get those right and Knockaround is one of the best value stories in sunglasses. Here’s how the pieces come together.

UV protection is standard; polarization is a choice

Every Knockaround lens is rated UV400, which the American Academy of Ophthalmology treats as the one spec that actually protects your eyes — a label reading UV400 or 100% UVA/UVB, not lens darkness or price. So on the protection question, Knockaround is covered across the board. Polarization is the variable. The Premiums, Fast Lanes and Paso Robles all come in polarized versions, but non-polarized trims of the same frames exist to hit a lower price, so read the listing. Polarization is a separate benefit — it removes reflected glare off water, roads and glass — and our polarized sunglasses guidecovers exactly when it’s worth selecting. If you’re weighing it against protection, our UV protection guide untangles the two.

How the three models compare

The Premiums are the classic: a squared shape that flatters round and oval faces and reads as an everyday pair. The Fast Lanesare the sportier option — a slightly wrapped, grippier frame that suits running and active wear better than the flat classic, without going full shield. The Paso Robles is the softer, rounded-square shape that reads a touch dressier and suits more angular faces. All three carry the same UV400 spec and the same customization; the choice is about your face and your use. If shape is the deciding factor, our face-shape guide lays out the rule.

Choosing your lens color

The lens color you pick isn’t just cosmetic — it changes what you see. A neutral gray or smoke lens keeps colors true and is the safe all-rounder; amber, brown and rose tints lift contrast, which helps in flat or overcast light and for anything where you want depth to pop; and the mirrored colorways are mostly about looks and a bit of extra brightness cut. Because Knockaround lets you choose the lens independently of the frame, it’s worth matching the tint to the light you’re usually in rather than defaulting to the darkest option — darker isn’t more protective, since UV blocking comes from the built-in filter, not the tint. Our lens colors guide has the full tint-by-condition breakdown so you can spend your one customization choice well.

Where the money shows — and who should look elsewhere

At this price the trade-offs are the expected ones: hinges, coatings and lens clarity are budget-tier, and the frames are one-size, so they won’t match a fitted or optical-glass pair for polish. That’s a fair deal, not a flaw — but it does mean you should skip Knockaround if you want edge-to-edge premium clarity, a lens that’s guaranteed polarized without checking, or a precise fit for a narrow or wide face. If you like the cheap-and-cheerful approach and want the other obvious contender, our goodr vs Knockaround comparison and the wider best sunglasses roundup put it in context.

Frequently asked questions

Do Knockaround sunglasses block UV?

Yes. Every Knockaround lens is rated UV400, which means it blocks 100% of UVA and UVB light out to 400 nanometers. That's the one spec the American Academy of Ophthalmology says actually protects your eyes — it depends on the built-in UV filter, not on how dark or how expensive the lens is. Whichever frame or lens color you customize, the UV400 protection is standard across the line.

Are Knockaround sunglasses polarized?

Some are, some aren't — this is the detail to check before buying. Knockaround offers polarized versions of its popular frames, including the Premiums, Fast Lanes and Paso Robles, but it also sells non-polarized trims and colorways of the same frames at a lower price. UV400 protection is standard on every pair; polarization is an option you select. Read the specific SKU's lens description if glare control matters to you.

What's the difference between polarized and non-polarized Knockaround?

Both block 100% of UV, so both protect your eyes equally. The difference is glare: a polarized lens filters out the horizontal reflected glare that bounces off water, wet roads and glass, which the AAO describes as the reason to choose polarized lenses. A non-polarized pair still cuts brightness and blocks UV but leaves that reflected glare. If you fish, boat or drive a lot, pick the polarized SKU; for general everyday wear, either works.

Which Knockaround model should I buy?

Pick by face shape and use, since all three carry the same UV400 lens. The Premiums are the squared everyday classic that flatters round and oval faces. The Fast Lanes are the sportier, slightly wrapped frame better suited to running and active wear. The Paso Robles is a softer rounded-square shape that reads a bit dressier and suits more angular faces. Then choose your frame and lens colors from Knockaround's customization options.

Are Knockaround sunglasses good quality for the price?

For the money, yes — with realistic expectations. You get genuinely UV400 lenses, polarized options and huge color customization for a budget price, which is a strong value. What you don't get is premium build: the hinges, coatings and lens clarity are budget-tier, and the frames are one-size. If you want edge-to-edge optical clarity or a precise, durable fit, you're shopping a different tier; if you want a specific-looking, protective pair you won't cry over losing, they deliver.
