The Joker Fort Knocks
Chaos never looked so cool. The Joker Fort Knocks channel Gotham City’s crown prince of chaos with a punchy green and purple colorway straight from the asylum. Built on our best-selling Fort Knocks frame, these shades feature spring hinges for all-day comfort and a larger fit that’s no joke. Polarized purple-green nebula lenses cut the glare while you stir the pot. Whether you're plotting mayhem or just making your daily rounds, these sunglasses add a wicked twist to your style. Slip ’em on—and remember, it's always fun to watch the world burn (just a little).

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.
