Inspired by the United States Bullion Depository in Fort Knox, Kentucky, these high quality, form-fitting sunglasses make for a comfortable and flexible fit. Best on larger head shapes, the Black on Black Fort Knocks Rx offer a timeless silhouette—perfect for your next pair of prescription sunglasses.
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

Black on Black Fort Knocks Rx
Sunshine 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!
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 CleanHub to recover and remove plastic waste before it can reach our oceans!
