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.

Polarized sunglasses make everything clear and blocks out glaring sun, nice fit on my nose brim and solid build. Cool shade of blue in the lenses

The shipping was extremely fast for an RX pair of glasses. Only thing I wish is points or insurance could be applied to the purchase.

I could not wear my Knockaround sunglasses anymore because my eyes got older. I was hoping for RX glasses and finally they have them. These Fast lanes have always been my favorite. They fit perfectly and the prescription lense is accurate. I bought these when the progressive lense was available. Extremely happy with these glasses.

Prescription is spot on. Frames are perfect. But the speed from ordering to delivery? Stellar! Will be ordering a second pair in the near future!

Very comfortable prescription sunglasses. Great for driving as they are not so dark that I cannot see my instrument cluster. Prescription was just right for driving sunglasses.
