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.

First time purchasing prescription sunglasses

This is my first pair of proscription sunglasses and I am very happy with my purchase.

I have worn the fast lanes for 10 years before finally getting them with my prescription. I chose these because I love the style and couldn’t find anything comparable on other websites with the style and price. I will be purchasing these again when these ones are ready to be retired.

Liking my new Knockaround Rx sunglasses!

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

Nice and comfortable, look great too!

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.

Finally!

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.

Great Rx Sunglasses

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.
