Want the Best Fishing Sunglasses?

Traditional Lens Colors Are "One-Trick Ponies". Sanofan Polarization Booster Fishing Sunglasses Fix This Flaw!

Smart Color Lens Fishing Sunglasses

"I am able to see many more fish that were invisible to me before."
— William Harrison, USA

The One Major Flaw All Lens Colors Have

Think about this for a moment:

Even in sunny Australia, light conditions on the water change during the day

Let alone places like the UK, where the weather changes faster than any forecast.

Unfortunately, traditional color lenses completely fail to adapt to these situations:

  • Yellow, amber, and rose colors make you squint as soon as the sun comes out…
  • Copper, brown, and gray make you feel like sitting in a cave and strain your eyes in the dull morning and evening light.

In other words:

You could spend $150, $200, or $300 on a pair and still just have a "one-trick pony"—expensive fishing sunglasses that only work in either low light or sunlight

Even worse:

More and more sunglasses brands cash in on this color limitation by making you buy a second or third pair — one for each light condition they can come up with.

But now you can save your money because…

Sanofan fishing sunglasses fix this embarrassing lens color flaw once and for all, while boosting polarization at the same time.

Want to know how it works?

Let me explain…

From Low light to Full Sunglight

The Only Fishing Sunglasses for All Weather Conditions

Sanofan fishing sunglasses with smart FluidTint polarized lenses have the two most effective lens colors already backed in:

Each FluidTint lens contains millions of specialized particles that absorb energy from the sun to change color from amber to copper.

This is called a photochromic reaction, and as a result...

FluidTint lenses adapt automatically—on autopilot—depending on changing light conditions... so that you can focus on the fish.

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

Why This Is Better Than Simple Polarization

You see, most anglers don't know this…

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

In fact, amber and copper are the ONLY lens colors to sharpen contrast and boost polarization.



They do this by blocking high-energy blue light from entering your eyes.

This is a big deal…

Because our eyes cannot focus sharply on blue light. As a result, things appear less defined and even blurry.

But with amber and copper, everything around you instantly appears sharper, crisper, and with more definition.

Other lens colors (including gray) don't improve your vision at all, as they allow blue light to hit your eyes completely unfiltered.

The good folks at Orvis agree:

Light brown, copper, and amber all sharpen contrast by reducing blue light
Choosing the Best Sunglasses for Sight Fishing

And of course, fly fishing legend, book author and podcast host Tom Rosenbauer, has known this for a long time:

Amber and copper lenses are my choice for sight fishing.
The Ultimate Book of Fly Fishing, page 135

Sanofans with FluidTint technology give you the advantages of BOTH colors:

On a cloudy day, or when wading in the shade of a tree, your eyes enjoy a crisp amber color.

Once the sun comes out, these lenses magically get darker and smoothly turn into a pleasant, high-contrast copper color.

Sanofan Sunglasses

The Sunglasses arrived as promised and were very well packed. I have worn these on several occasions and sometimes up to 7 hours, because they are so light I had forgot I was wearing them. Although they are very light they seem very strong and well made. I have had Sunglasses three times the price and not lasted 5 minutes. I do a lot of driving and use these Sunglasses all the time during the day and they also reduce my eye strain. I don’t write many reviews but feel a good product should get a good review.

Tommy Thompson (Anchorage, AK, US)

I can not wait to use these next year fishing, they work great!

Doug Knapic (Nanty Glo, PA, US)
Great glasses

I glasses did everything they were supposed to do. I use these glasses exclusively for stream fishing.The lens color let me see into the water pretty good They changed shades as the sun came and went. Nice to have a pair of glasses that gets brighter in the evening as the sun was going down . Be nice if they came with a bifocal for tying on flies

Caleb Davis (Ann Arbor, MI, US)
Relief for my eyes

I didn't get these glasses for fishing as I don't fish that often. I have issues with glare and the Sanofan glasses are superb. I can now drive for hours without an eye strain. What a relief. Thanks

Ron Kaliszewski (Lake Orion, MI, US)
good for driving

These sunglasses are intended for fishing but after reading the specifications I decided that they might also be good for driving. I found them to be the best sunglasses I have ever owned. They darken a little and they reduce glare and enhance color. I even use them on cloudy days. Most other sunglasses just make everything darker and harder to see details. I have not used them for fishing. I am sorry that someone didn't understand that my comment was intended as a compliment to the quality of these sunglasses.

All You Need to Know, Quick and Honest

Why Amber and Copper? Why Not Gray?

Removing blue light is essential in enhancing contrast. This is because blue light tends to scatter in the eye, making it difficult to focus.

Only yellow, amber, and copper lenses can block blue light. In fact, this is what makes them special.

All other lens colors, including gray, let blue light rays hit your eyes completely unfiltered.

Even worse:

As your pupils widen behind dark gray lenses, much more blue light reaches your eyes' retina.

So why not yellow lenses?

Yellow lenses are good at increasing contrast, but terrible at removing glare from the water surface.

And here is why:

A good polarization filter makes a lens darker by default by removing all visible light rays of a specific angle.

Unfortunately, yellow lenses can't be made darker, or else they wouldn't appear yellow anymore.

So, in order to market them as "polarized", yellow lenses tend to come with a weaker form of polarization that is less dark but leaks reflective light.r text here...

What About Mirror Coatings?

First, in order to avoid confusion:

Mirror coatings in silver, blue, or green are not lens colors, but just a thin layer on top of the actual lens.

Their main purpose is to cut out even more sunlight, which makes them uncomfortable to wear in low-light situations like dawn, dusk, and on overcast days.

This is why we don't use them.

Also, if applied directly to the lens surface, those shiny metal coatings are naturally prone to scratches.

Will They Fit My Head?

Thanks to metal spring hinges with a wide opening angle, as well adjustable temple tips, every pair fits like a glove and never falls off, regardless of the size of your head:

30 Degrees Spring Hinges

Spring hinges + adjustable node pads + adjustable temple tips

Adjustable Temple Tips

Adjustable Nose Pads

And because of the adjustable nose pads, you don’t need to worry about the size of your nose, either.

I like how they sit away from your face just a bit, so they breathe and don't fog up like most sunglasses I wear do.

Are They Good for Hunting (Boating, Golfing, etc.)?

Sanofans are the perfect choice for all fishing activities like fly-fishing, carp fishing, and bass fishing.

But being able to maintain perfect vision in all weather conditions is crucial for many applications, such as boating, hunting, and golfing... and even clay pidgin shooting: 

I have used them driving and hunting, and they have performed great.

-- James Dooley, USA

Really helps seeing wild life. Great for hunting and fishing

-- Zane Young, USA

I would highly recommend these glasses to any avid fisherman or golfer.

-- Neal Gilliam, USA

I'm not a fisherman, but the sun glasses are great for playing golf and driving.

-- Faye Bartley, USA

They do the job exceptionally well, [...] especially when i’m clay pigeon shooting

-- Is Dupoy, United Kingdom

Can I Use My Sanofans for Driving?

Sanofans with FluidTint lenses work great for driving in daylight, where they sharpen contrast and remove reflections from the windshield.

Just note that inside a car, the color change won't be as apparent as outside.

This is because the windshield filters out part of the UV rays that are responsible for the darkening effect of the lens.

A word of warning:

Sanofans are not suitable for driving at night. For night driving, only glasses with yellow lenses should be used.

If you are ok with this limitation, you'll enjoy wearing your Sanofans in the car:

They are great fitting sunglasses, not just good for fishing but excellent for driving 

-- Dwight McLeod, Canada

I ordered 2, so I could use a pair while driving and one for fishing

-- Eric S., USA

Loved them so much I bought a second pair for driving

-- Rodney Bond, USA

Why Don’t More Brands Offer Light-Adaptive Lenses?

My guess: It's because it would hurt their bottom line.

Instead of you just selling you only one pair that works all the time, it's much more lucrative for them to make you buy different sunglasses for overcast and sunny days, lake fishing and stream fishing.

So, if they offer light-adaptive sunglasses, they are especially expensive.

Now, you might ask:

"Why do you only sell one kind of fishing sunglasses?"

The better our sunglasses, the more we sell through word of mouth marketing. So by making the only fishing sunglasses you'll ever need, everybody wins.

Am I'm Protected Against Harmful UVA and UVB Rays?

Sanofans with FluidTint lenses shield you from all UVA and UVB rays and pass US standard ANSI Z80.3:2018.

Here's the test result:

sanofan sunglasses pass ansi Z80 standard

As you can see, Tmax UVB and Tmax UVA are both at 0.00%, which means FluidTint lenses blocks all rays of that light range.

Now, this is important:

Not all sunglasses that pass this standard fully protect your eyes.

Standard ANSI Z80.3:2018 allows up to 3.76% UVB and a whooping 30.10% UVA radiation to reach your eyes, while still being considered "UV protective".

So make sure to always ask for the actual test report before making a decision.
