New: Flaw-Proof Fishing Glasses

Get the Best Polarized Fishing Sunglasses by Avoiding the #1 Lens Color Flaw

Confused by All Those Lens Colors?

If you've been scratching your head trying to make sense of all those lens colors and mirror coatings... it's NOT your fault.

It's because all traditional lens colors suffer from a major flaw.

Luckily, there's now a simple and fast solution every angler can apply.

In fact, you can have your flaw-proof polarized fishing sunglasses in as little as 3 minutes...

And make your fishing buddies jealous.

All you need to do is make sure you don't fall into this trap:

Why Most Anglers Waste Weeks on Google and YouTube

For a long time I was confused myself.

But after scouring through countless articles and videos on fishing sunglasses, I finally discovered...

Why choosing the right fishing sunglasses is so frustrating (and what to do about it).

It's because of this major limitation all lens colors have:

Lens colors are completely unable to adapt to light changes.

Not big a deal? Far from it.

In fact, many anglers waste weeks on Google and YouTube, desperately looking for the 'best' lens color...

Until they realize this truth:

All fishing sunglasses are limited to low-light (amber, rose, yellow) or sunlight (brown, copper, gray).

Why is this a problem?


Even in sunny California and Australia, the light keeps changing from dawn to dusk. 

Let alone in places like Northern Europe and the UK, where the weather changes faster than any prediction. 

In other words: 

Spending your hard-earned money on fishing glasses that only work half the day is a bad idea.

This is why my team and I decided to develop a new color lens that has a very special advantage.

So what is the secret?

You Can't Go Wrong Anymore!

Modern fishing sunglasses are Smart

I'm talking about polarized fishing sunglasses that select the right lens tint for you.

This FluidTint lens technology is a game-changer because...

You can't make a mistake anymore.

Put it another way:

From now on, you always get the best lens tint—even if you don't know anything about lens colors and just want to enjoy your fishing.

Let me explain.

From Low light to Full Sunlight

Removing the Burden of Having to Pick a Lens Color

Sanofan fishing sunglasses with FluidTint technology...

Combine the 2 best lens colors—amber and copper—into a dual-color lens.

Now here comes the best part:

FluidTint lenses change color on autopilot, depending on the amount of sunlight.

So instead of you having to choose a lens color upfront, Sanofans make that decision for you, in real-time, many times a day:

  • From dusk to dawn
  • On cloudy and sunny days
  • In Spring, Summer, Fall, and Winter

You may be wondering:

Why amber and copper? Why not gray? And what about mirror coatings?

Before I go into that...

Let's first see how Sanofans look like:

Enjoy perfect vision over the FULL range of sunlight. (Please allow a few seconds for the video to load).

It's like having 10 pairs off glasses in my bag. One pair really does everything.

How Amber PLUS Copper Supercharge Polarization

Polarization makes fish visible. But only high-contrast lenses allow them to stand out against the bottom.

Here’s the deal:

Only amber and copper are able to supercharge polarization this way.

Why is that?

Amber and copper block 100% of high-energy blue light rays from entering your eyes.

This is important because...

Blue light tends to scatter inside the eye, making it difficult to focus.

As a result, our eye's ciliary muscles constantly work overtime, causing headaches and blurred vision.

But with amber and copper cutting out blue light...

Your eyes stay relaxed all day and everything appears sharper, crisper, and more defined.

Colors pop and fish have no way to hide.

This is the first pair of polarized sunglasses that I can truly say I love.

No Other Lens Color Comes Close

Let me tell you a little-known fact:

Other lens colors (including gray) do not sharpen contrast at all.


Because they allow blue light to hit your eyes completely unfiltered.

The only exception is yellow lenses.

Unfortunately, these have a rather large drawback:

Yellow lenses are good at increasing contrast but poor at removing glare.

How’s that?

Polarization filters make lenses darker by default, which is bad for lighter lens colors such as yellow. 

As a workaround, yellow lenses often come with a weaker form of polarization that is less dark but leaks reflective light rays.

So what about mirror coatings like silver, blue, and green?

Mirror coatings act like window blinds, which makes them uncomfortable to wear in anything but bright sunlight.

What's more:

Mirror coatings do not remove glare from the water surface (only good polarization does).

This is why pro anglers swear by amber and copper lenses…

You Are in Good Company

Fly fishing legend, book author and podcast host Tom Rosenbauer doesn't beat about the bush:

Amber and copper lenses are my choice for sight fishing.

Ultimate Book of Fly Fishing, Page 135

The good folks at Orvis agree:

Light brown, copper, and amber all sharpen contrast by reducing blue light. 

Choose a brown or copper-colored lens for normal conditions on the flats, and an amber or yellow lens for cloudy, overcast conditions.

I'm finally able to see the fish.

Since I purchased my new sunglasses I am able to see many more fish that were invisible to me before. I am so happy!

Chris Hancock

Ray Skufca (Salida, US)

Very clear changes color fast great pair of sun glasses at reasonable price.

Mike Morasci (Coeur d'Alene, US)
Very pleased

Been a smith guide choice (glass lens) user for years and was hesitant to try these fluid tint lenses. After a few days on the water I have to say I'm impressed with the optics. The clarity and performance in all light conditions I've encountered so far has been terrific. The quality if the frames is great too. Time will tell as to how well the polycarbonate lenses will stand up to my usage, but so far I'm very happy with my purchase.

Very nice on the water in both bright sun or cloudy days. Loved them so much I bought a second pair for driving. Best shades at a very affordable price. I’ll never spend a fortune on shades again.
