Backcourt
Tennis balls are meant to stand out, and so are the Backcourt Premiums Sport. The front frames are frosted tennis-ball-yellow, and each arm displays a mid-match scene, complete with net, ball, lines, and court. Polarized hardcourt blue lenses, green embedded rubber nose pads, and optic yellow K-logos will have you feeling like you’re rallying with Serena herself.
Designed on our best-selling frame style, the Premiums Sport are form-fitting, universally flattering, provide full UV400 sun protection, and feature embedded rubber nose pads to reduce slip, slide, and bounce. Every pair comes with a hardcourt protective soft case and a holographic numbered edition card.

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.
Stay Glare Aware
Polarized lenses cut glare by filtering out horizontal light waves, like the ones that bounce off water or the road. Without this glare, you’re left with a more gentle view and reduced eye strain, not to mention crisper, cleaner details!

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.

Cool style of green sunglasses shape was different but I like how they kind of glow when wearing them in the sun. Blue tent to the lens.

I was pleasantly surprised at the quality of the sunglasses. They were purchased as my "beach sunglasses" meaning I don't care if I lose them, so I was expecting flea-market quality. These far exceeded that.

I've enjoyed this pair. The color scheme is quite great for tennis and pickleball. They are secure and motion free during play, staying put on my face quite well. I do wish they were a little less wide as I have a small oval face and the oversized makes me look like a child. Would love if they applied more styles like the Backcourts to the Classics frames.
