Yes, for what they are. A polarized Knockaround is a properly polarized, impact-resistant, UV400 pair from a brand that has sold millions of them and backs manufacturing defects for life. The two things to know before buying: not every Knockaround is polarized, so check the specific listing, and the grip is ordinary, so these are a hang-out pair rather than a run-in-them pair.
Knockaround occupies a slightly different slot from the other budget brands we cover. goodr optimizes for staying on a sweaty face; Knockaround optimizes for the number of ways a pair can look, and for not caring when one goes missing. Whether that is a good buy depends almost entirely on which of those two problems you have. The brand assessed model by model is in our Knockaround sunglasses review.
1. The polarized trap: check the listing
This is the single most common Knockaround buying mistake, and it is the opposite of the situation at Maui Jim, Costa and goodr, where every pair is polarized. Knockaround sells both polarized and non-polarized versions of frames that otherwise look identical, and the difference is a line on the product page rather than anything you can see.
So "are Knockaround sunglasses polarized?" has no single answer — some are, some are not, and it is on you to check. If glare control off water, wet roads or a car hood is the reason you are buying, confirm the specific pair says polarized before you order, and test it when it arrives. The thirty-second rotation test against an LCD screen is in how to tell if sunglasses are polarized.
The good news is that when a Knockaround does say polarized, it is genuinely polarized rather than a dark tint pretending — and it is UV400 either way, which is the standard the American Optometric Association recommends. UV protection is not the thing to worry about here.
2. The warranty, read properly
Knockaround's published warranty policy is unusually generous for the price, and unusually specific about its limits. Both halves matter.
What it covers: after a 45-day return and exchange window, pairs stay covered by a lifetime warrantyagainst manufacturing defects under normal use — specifically naming "hinge or spring failure," "frame assembly or finish defects," and "lens coating defects not caused by wear." An approved claim returns "store credit equal to your original purchase price to select a new pair."
What it does not cover, in the policy's own words: "Loss or theft," "Accidental damage (sat on, stepped on, run over, heat warping, pet chewing, etc.)," "Normal wear and tear (minor scratches or scuffs)," counterfeit goods or purchases from unauthorized sellers, international orders, and free or promotional pairs. There is also a limit of one warranty claim per paid pair.
Read together, that is a defect warranty, not an accident policy — which is the right thing to expect and worth setting your expectations to. The two exclusions most likely to catch a real buyer are scratches (the most common way a budget lens dies) and purchases from unauthorized sellers, so buy from a channel you can prove.
3. Where the budget shows
Grip. Knockaround uses standard acetate and plastic arms rather than a tacky grip coating. On a dry face that is fine. On a sweaty one they walk down your nose, and this is the clearest reason to buy a goodr instead if the pair will be worn while you exercise.
Optical clarity. Injection-molded polycarbonate, which sits at an Abbe value of about 30 against roughly 58 for glass — more color fringing at the edges of your view. It is perfectly good for general wear and it is not what you would choose for staring at a horizon.
Coverage. These are lifestyle shapes. Side light gets in, which is fine on a patio and a genuine gap on a bike or a boat.
Coatings over time.Budget lens coatings scratch, and scratches are explicitly outside the warranty. This is the failure mode to expect, and it is why cleaning them correctly matters more on a cheap lens than an expensive one — see how to clean sunglasses.
4. Alternatives at each price point
Same money, better for sweat. If the pair is going running, cycling or hiking, a grip-coated pair holds a wet face far better and costs about the same. That is the swap we recommend most often.
Same money, better for sport. A budget sport frame from a cycling brand trades the fashion range for coverage, venting and a wrap that keeps side light and wind out.
Cheaper. There is a real floor below Knockaround where polarization becomes a claim rather than a feature. The bottom-of-market pick below is about as cheap as a genuinely polarized pair gets before that line, and it is a spare-in-the-car purchase rather than a primary one.
More expensive, and worth it if you keep things.If you have not lost a pair in years, a proper acetate frame with a crystal lens is a different ownership experience — better optics, a frame that can be adjusted and serviced, and a look that does not date. The step-up is the last pick below, and the ladder between the two extremes is in are expensive sunglasses worth it.
