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 golfing 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.

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. No need to carry multiple pairs of sunglasses.

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

    Once it became cloudy, my other glasses were virtually useless, but my Sanofans changed color and I could still see clearly through the water.

Loved them!

I use these glasses for fishing. It's great to not have to change lenses or glasses during the day for changing light conditions and the glasses get dark enough to handle the bright Arizona sun during the day. Will be buying more.

Darryl Dankenbring (Temple, TX, US)
Fishing glasses.

Very effective in reducing glare. Very comfortable to wear.

Tim Johns (Sydney, NSW, AU)

Perfect fit and eye protection for me on the golf course or in the garden, money well spent.

Best Sunnies

Just want to give you some feedback on using your sunnies last week - just returned from 1 week fishing in new Zealand with my son and 3 grandkids ( I am 77yrs old, my Son 57, and grandkids 25, 20, and 19, and we used 2 guides to guide us all.
As you can see, a mixture of oldies, middlies and experienced guides using all sorts of sunglasses, from cheapest to most expensive, and in between.
I was blown away by how good your sunglasses are - exceptionally comfortable, light and, wow, what fish I saw ( and even caught quite a few ) and how clearly in all light conditions.
I let everyone try you sunnies ( including the 2 guides ) and all were amazed.
Thanks for making such great sunnies for trout fly fishing - I am sold on them for life.

Seeing into the depths

Able to see fish on the bottom with these glasses as well as wearing my
Smiths.. or Kaenons, or Costas....good value for the dollar

Tony, uro nyphing (Smithfield, PA, US)
bought for fishing

I bought these glasses just for fishing. I used them for the first time 2-3 23, the river was high due to the rain and I was able to see the bottom. The water was waist high. I would have never went out that deep with out them.

Gordon Kelly (Hobart, TAS, AU)
Seriously - The best sunglasses I have ever worn!

I purchased a pair of the Sanofan glasses not expecting the claims to hold up.......How I was seriously mistaken! I have had many more popular brands that cost hundreds of dollars and honestly, they don't compare. I was blown away by how comfortable they are, the clarity and the build quality are fantastic but the lenses.... OMG they do EVERYTHING they claim! I purchased them for playing Golf mainly, but they have quickly replaced my old sunnies for everyday use. Sounds like a dodgy cliché but I went and got another 2 pairs, so I have them in every vehicle I own. I'm not paid for this review, I don't work for the company and I'm not a friend of the owner BUT I do think on the rare occasion that a company provides a product that EXCEEDS expectations then talk it up and credit where it is due.

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.

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 You Need to Know, 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

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.

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.

What's worse:

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

In other words:

When wearing gray lenses, the problems blue light causes, like blurred vision and mild headaches, are likely 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 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.

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

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, lake fishing and stream fishing.

Now, you might ask:

"Why do you only sell color-changing 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.
