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.

It makes a difference and there are a lot of them. So we put together a short quiz to help you decide.

Questions About Replacing Your Maui Jim Guardrails MJ327 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.

4th order

"Fourth time I’ve ordered from them. Kinda says it all."

— David G. (5/5)

Great Result!

"Revant was a great solution. I was able to replace some old lenses from a pair of Maui Jims sunglasses!"

— Chester S. (5/5)

great optics, clarity and reasonable price

"I liked the replacement lens for my Maui Jims; fitment was perfect. The screwdriver supplied was a bit weak, but a decent, good-quality small Phillips screwdriver did the trick, and fitting the replacement lens worked like a charm. As mentioned, the optics were clear, like new, or maybe a tad better. I did purchase the upgraded lens from Revant; I'm unsure if the standard optics are as good as these upgraded ones. I recommend these replacements."

Maui Jim lens

"Great lenses! I was almost going to throw out these sunglasses! Replacing the lens saved me a bunch of $"

— Michael E. (5/5)

Love the lenses

"Fit and finish is perfect. Installation was simple and the added screwdriver made things even easier. These were purchased to replace the lenses in my Maui Jim's. There was nothing wrong with the original lenses, I just found them to be too dark for general wear (when not on the water or in snow). I absolutely love the crispness and clarity of Revant's lenses. Maui Jim makes some of the best lenses I've found and the ones from Revant are just as good. I plan on ordering several more pairs for other sunglasses. I'm very happy to have found this site. Thanks"

— Robert B. (5/5)

Elite lenses - mediocre

"Decent lenses if you're the kind of guy who carries a case in his pocket at all times. I don't. Lenses were scratched within 3 days. Extremely soft plastic/coating. Better off buying a $20 pair of polarized from Walmart. Embarrassing that these are made is USA"

— Jared V. (2/5)

Awesome!

"Fit perfectly and came with a little screw driver. Went from tossing my Maui Jim's away to feeling like I have a new pair"

— Ryan K. (5/5)
