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

Questions About Replacing Your Costa Blackfin Lenses?

Can I replace the lenses in my sunglasses?

Yes, most name-brand sunglasses have lenses that can be replaced. Revant lenses are custom-cut for specific frame models and include installation instructions. In most cases, you can replace the lenses at home in under two minutes.

How do I know if Revant lenses will fit my frame?

Check the model name or number printed on the inside temple of your sunglasses. Revant lenses are made for exact frame models, not just similar styles. If the model on your frame matches the one listed on our product page, you’ll get a perfect fit.

If you're unsure or don't see a model name or number, contact us and we can help make sure you get the right lenses for your sunglasses.

What’s the difference between Revant lenses and my original lenses?

Revant lenses are aftermarket, not OEM, but they’re engineered to meet or exceed the performance of original lenses. Each lens is traced from the original frame model using high-precision digital scanners that capture its unique curvature and edge geometry down to fractions of a millimeter. That means you get a lens cut to fit your frame exactly. No guesswork, no gaps, and no rattle.

Beyond fit, Revant lenses are tested for optical clarity, impact resistance, and durability. We also offer upgrades like polarization, MirrorShield® tints, anti-reflective coatings, and hydrophobic layers that go beyond what many stock lenses provide.

Reviews

New lenses

"I followed the instructions and the installation video and found that they went in very well"

— Gary S. (5/5)

Hard to Replace

"I received the noodle lenses for my Costa, Del Mar, black fin sunglasses, which had original glass lenses. After watching the video on how to replace them, I worked for several hours and was not able to remove the glass lenses, but did manage to break one of them. After writing to the company, I was told that oh by the way, if you have glass lenses, you probably need to go to a local optical professional to have him help me. Would’ve been nice to know this ahead of time. I have no idea how the new lenses are since I haven’t been able to get them in yet."

— William S. (5/5)

Q&A

I have costa Blackfinn BL 114 frames. Will the standard 50s or do I need to get the pro?
The standard Blackfin lenses should fit your frame. All of our products come with a great 60-day no-hassle return policy as well as a 1-year manufacturer's warranty. If for some reason your purchase doesn't work out, we've got you covered!
I have costa black fin BL 11 will these lenses work? And if so should I ordered the standard or the pro?
Hi Courtney, yes the Standard Costa Blackfin replacement lenses should fit your frames perfectly! The Pro shape lens is for a different model of Blackfin frames.
Are these polycarbonate or glass lenses?
Since advanced impact resistance is a key component of Revant lenses, our lenses are exclusively made from high-grade optical polycarbonate. They've been precision-tuned to offer advanced clarity and durability to ensure that you're getting the best viewing experience possible; all while ensuring that your eyes are protected not only from harmful UV Rays, but from objects as well. If you're looking for glass lenses specifically, I recommend contacting the original manufacturer of your sunglasses. If you'd like to give our lenses a try, you're welcome to take advantage of our 60-day no-hassle return policy should they not be to your liking.
