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 Stealth Black

Make your old Costa KC lenses like new with our replacement lenses for Costa sunglasses. And because our lenses meet or exceed the quality of your original KC lenses, you'll get the same performance you've come to expect.

Our Stealth Black lenses cut glare and block 88% of visible light. Plus, a neutral tint means no weird purple shades from the 90s.

Other Features We Like to Nerd-Out About
  • Best for bright light (12% light transmission)
  • Neutral tint looking through the lens
  • Anti-scratch protective coating
  • Lens material: optical polycarbonate
Comes With
  • 1 pair of replacement lenses (left & right) for your Costa KC sunglasses
  • Screwdriver for sunglass lens installation
  • Protective microfiber bag for storage and cleaning
  • Costa KC lens care instructions
  • Note: sunglass frame not included

Better Performance.
Half the Price.

Do I Really Need Polarized Sunglasses?

Polarization cuts glare, increases visibility, and lets you see underwater. In short, it helps you do the things you love better. And once you’ve taken that hairpin without getting blinded or looked a fish straight in the eye, you’ll never go back.

Unmatched Quality

We don’t know everything, but we know lenses. The last ten years have been all about testing, testing, testing. Every single material, coating, and manufacturing method has been evaluated. Only the best are used for our lenses.

  • High Impact Resistance
  • Polarized to Block Glare
  • 100% UV Protection
