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.

I generally order new Knockarounds around the summer to prepare for pool days. This year I opted for the Blue Obsidian Fort Knocks. I love the color! I also think the quality of these is much better than some I've had in the past. I've already received several compliments.

I purchased these for my lady. Her favorite color is blue. She wore these the next day after they arrived. She said they were great for her walk.

Knockarounds are my “go to” for sunglasses. I have a large head and the Fort Knocks is a perfect fit. They are high quality for a low price.

Knockaround never disappoints, The Blue Obsidian is a perfect color. Looks great, the quality is every bit what you would get from those overpriced “ Designer “ sunglasses. Small business first all the time
