Inspired by the legendary Fender® Stratocaster™, these Fort Knocks Rx hit every note of cool with their guitar-neck arms and fretboard detailing. Just like a Strat bridges the gap between bluesy lows and screaming highs, these shades blend iconic Surf Green and white fronts with a touch of vintage wood grain, mirroring the guitar's timeless body. Silver hardware and the iconic Fender® logo etched on the lens round at this sweet pair of shades.
Whether you're headlining a festival or just jamming out on a sunny day, these are your go-to sunglasses to rock the look. Let's face it—every music legend needs to shield their eyes from the glare of the spotlight.

In 2022, Knockaroud officially became Plastic Neutral—for every pound of plastic we use, we remove one pound from the environment elsewhere. But that’s far from where our sustainability efforts end. We’ve also implemented minimalist, recycled packaging, eliminated single-use plastics, and included recycled materials in our products whenever possible. There’s always more progress to be made, but we’re committed to putting in the work.
Who we are
Born, raised, and bathed in San Diego sunshine, Knockaround is the original, affordable sunglasses brand. Since 2005 we’ve committed to making durable shades that are both practical and stylish. Our stellar customer service and ever-growing selection of high-quality eyewear have made us not just hometown favorites, but go-to’s across the globe!
Committed to Sustainability
Making high-quality shades is the core of what we do, but inevitably that means we contribute to excess plastic byproduct. The idea of being a net drain on the environment doesn’t sit well with us, so we partnered with 4ocean to maintain plastic neutrality and work further to improve the environmental friendliness of our process.

My first pair of RX sunglasses, they did a spectacular job! Deluxe case, excellent Fender inspired design.
I won't hesitate to order RX glasses form them again. Reasonably priced and prompt turnaround.

I got these prescription sunglasses for my son-in-law when he bought my daughter and grandson down to visit this winter in Florida.
He loves them and is seriously styling.

First time Knockkaround customer so I didn't quite know what to expect and of course, I started with a prescription lens order to boot - but I am so surprised to see the quality and the great fit!
Ordered this model in prescription sunglasses and couldn't be happier!

Glasses fit great, a bit big for me (female with small head) but overall fits great and will fit great on any average sized adult. Love the color!

I really like these shades, but I have the same problem that I had with the glasses I was replacing: they don't stay on the brim of a baseball cap. If the arm springs were a little tighter it would solve the problem. This is such a shame, because they look great and are very comfortable to wear. But sometimes you need to park them, and they need to stay put.

I play fender bass and these were a no brainer. I got these as a set of clear Rx and people notice them wherever I go. I just love them.
