sustainability

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.

shipping & returns

We ship Monday to Friday from our warehouse here in San Diego, CA, with the exception of holidays.

Stay Glare Aware

POLARIZED LENSES

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!

In The Wild

Knockaround Sunglasses and Forbes

Knockaround Sunglasses and Newsweek

Knockaround Sunglasses and Men's Health

“The selection styles are massive and always changing. If that isn't enough, you can even customize your own frames.”

Who we are

Sun and San Diego

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!

Plastic Neutral

KNOCKAROUND IS PLASTIC NEUTRAL

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.
