Obsidian Fort Knocks
A sophisticated combination of retro and modern tastes, our Obsidian Fort Knocks sunglasses check all the boxes and then some. Prominent black-to-clear gradient shading on the fronts mirrors your smooth finesse, while black arms and inner transparent accents offer a nice mix of playful and fashion-forward. Polarized smoke lenses also provide UV400 protection and impact resistance for any forays into unexpected fun. Catch some eyes with dark chrome accents on the front, and don’t forget to show off the fancy arm script to anyone in need of some style guidance.

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.
