Don’t Waste Money on Flawed Sunglasses

Think about it:

Even in sunny Australia, lighting conditions vary throughout the day.

Not to mention countries like the UK, where the weather can change instantly.


Traditional sunglasses are dumb:

  • Yellow, amber, and rose lenses make you squint when the sun comes out.
  • Copper, brown, and gray make you feel like sitting in a cave in low light conditions.

In other words:

You can spend $100, $150, or $200 on fishing sunglasses… only to have them fail every time a cloud passes by.

So let's…

Fix the #1 lens flaw once and for all!  

Want to know how it works?

Let me explain…

From Low light to Full Sunlight

How Smart Fishing Sunglasses Work

Sanofan fishing sunglasses combine the two best colors for fishing into a single lens.

And this is where the magic happens:

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

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

The perfect amount of light reaches your eyes at any given time, whether it's low light or sunlight.

FluidTint lenses adapt automatically—on autopilot, eliminating the need for multiple pairs of sunglasses.

See the Difference! (I am using a small UV lamp to imitate the color-changing effect of sunlight.)

In one word GREAT
I’m a keen lawn bowler, drive , doing airport drop offs plus wine trips ect, with out doubt the best glasses I’ve ever had, everything is not only clear and visible but it’s like having a burst of sunlight showing me the way, even driving in the rain , I still leave them on
Thank you
My only comment is maybe a little higher over my nose, but not sure as I’m not swapping what I have
Regards John

Hi John,

Thank you for your fantastic feedback!

If you prefer your sunglasses to sit higher or lower on your nose, all you need to do is adjust the position of the nose pads, which only takes a few seconds.

Kind regards,

Harold Distler (Overland Park, KS, US)
Great glasses

I use mine for driving’s and motorcycle riding. Great clarity and brightens up everything yet does a great job of reducing glare

Sanofan sunglasses

I purchased a pair of Sanofan sunglasses a couple of weeks ago. The service was excellent with delivery to NZ in less than a week. I have just had cataract surgery and as soon as I was able to hit the golfcourse, the benefits of the glasses were obvious. Any glare was absent and the colors are true. Thanks so much.

Bonus: True Supercharged Polarization

You see:

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

We call this "Supercharging Polarization".

In fact:

Amber and copper are the ONLY sunglass lens colors to sharpen contrast, increase resolution, and boost polarization.

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

This is a big deal because…

Our eyes cannot focus on blue light, causing eye strain and blurred vision.

Other colors like gray are unable to compete, as they let blue light 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

Fly fishing legend, book author and podcast host Tom Rosenbauer, recommends them too:

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

Now, here comes the good part:

Sanofan fishing sunglasses supercharge polarization by combining the power of BOTH, amber and copper, in a single lens!

All Questions Answered, Quick and Honest

Will They Fit My Head?

Thanks to metal spring hinges, adjustable temple tips, and our special morph frame, every pair fits like a glove and never falls off, regardless of the size of your head:

30 Degrees Spring Hinges

color-changing sunglasses that fit every head size

Spring hinges + adjustable node pads + adjustable temple tips

Adjustable Temple Tips

Watch this short video to see how to quickly adjust the 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.

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.

But 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.

What's worse:

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

In other words:

When wearing gray lenses, the problems blue light causes, like blurred vision and mild headaches, tend to get worse.

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 removes all visible light of a specific angle, which makes the lens appear darker. 

As yellow lenses cannot be made darker or else they would loose their light tint, a weaker form of polarization is used that leaks reflective light. 

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.

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

Sanofans are the ideal option for golfing and fishing, including fly-fishing, carp fishing, bass fishing, and more.

However, maintaining optimal vision in various weather conditions is essential for numerous activities, including boating, hunting, and even clay pigeon 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

Are the Glasses the Same for Fishing and Golf?

Yes, they are.

Yes, they are the same. The separate pages for fishing and golfing are intended to highlight the specific applications for each sport.

As you can see on the reviews page, our customers wear Sanofans for various activities including fishing, golfing, driving, cycling, hunting, and sport shooting.

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 selling you just one pair that works all the time, it's much more lucrative to make you buy separate sunglasses for overcast and sunny days.

Now, you might ask:

"So why do you sell color-changing sunglasses?"

The better our sunglasses, the more we sell through word of mouth marketing. So by making the only 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.
