Replacement Lenses That Don't Feel Like Replacements

Polarized for the Win

Life can be polarizing, but polarized sunglasses aren't. They reduce glare so you see the good times better.

You Only Get One Set of Eyes

Our replacement lenses protect against 100% of those damaging UVA and UVB rays. No staring contests with the sun though.

Tough Enough for Spicy Stuff

We've put our lenses through all kinds of science-y tests and a few not so science-y ones too.

Revant Replacement Lenses for Dark Brown

Make your old Knockaround Fast Lanes Sport lenses like new with our replacement lenses for Knockaround sunglasses. And because our lenses meet or exceed the quality of your original Fast Lanes Sport lenses, you’ll get the same performance you’ve come to expect.

Dark Brown features a warm brown view-through that enhances contrast while reducing blinding surface glare. It improves comfort and visual definition for hiking, camping, birding, sports practice, and long afternoons outdoors.
