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.
Unfortunately…
Traditional sunglasses are dumb:
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!

From Low light to Full Sunlight
How Smart Fishing Sunglasses Work
Sanofan fishing sunglasses blend the two best lens colors for fishing—amber and copper—into one.
Here’s where the magic happens:
Each FluidTint lens holds millions of specialized particles that react to sunlight, shifting from amber to copper and back:
See the Difference! (Each pair includes an instant color-change test.)
This photochromic reaction ensures one thing:
FluidTint lenses seamlessly adjust light transmission (VLT = how much sunlight reaches your eyes) between 10% (copper) and 35% (amber).
This means that...
From sunrise to sunset, your eyes always receive the perfect amount of light.
Traditional lenses? They’re stuck with a fixed VLT, pushing you to buy multiple pairs just to handle changing light.
See how we compare (from dark to light lenses):
| Lens Type | VLT |
|---|---|
| Costa Blue Mirror | 10% |
| Costa Green Mirror | 10% |
| Costa Gray Silver Mirror | 10% |
| Costa Copper Silver Mirror | 12% |
| Costa Gray | 12% |
| Costa Copper | 12% |
| Maui Jim Neutral Grey | 12% |
| Smith Brown | 14% |
| Smith Gray Green | 15% |
| Maui Jim HCL® Bronze | 16% |
| Maui Jim Maui Rose® | 20% |
| Costa Sunrise Silver Mirror | 25% |
| Maui Jim Maui HT™ | 25% |
| Smith Ignitor | 32% |
| Sanofan FluidTint | 10%-35% |
Even better:
700+ testimonials prove that FluidTint lenses consistently deliver on their promise:

— Eric S., USA - 3The changing lenses are awesome and become dark enough for the brightest sun.
— Robert Hollister, USA - 4I could see my bait under water at 10 - 15 yards. Actually watched fish come up and take the bait.

Being an X-NFL football player, I depended on the best sunglasses that were on the market. I know and had the experiences from hunting elk, mule & whitetail deer and feral hogs, hunting and guiding many years. These Sanofan glasses exceed many of the top brands that I have experienced. They are the best. Thank you!
These are the best sunglasses I have used to date while golfing. I see the ball so much better down the fairway than my other sunglasses that I paid twice as much for. I would definitely recommend these for anyone who wants very good clarity and performance while golfing for a far better price.
I absolutely love these sunglasses. No more eye strain. Super clear view. These glasses work at low light as well as bright sunlight. I don’t have to take them off because of shadows like other sunglasses. Highly recommend Thank you.
I have tried for years to play a complete round of golf wearing sunglasses but eventually I would take them off because I didn’t trust them when putting. The Sanofan sunglasses are the only ones I have worn for a full round of golf because I found I can read putts so much better wearing the glasses and I’m getting more putts. I couldn’t recommend them highly enough.
Best sunglasses for golf . Clarity of the ball and depth perception is perfect.
Everything that I want in a pair of fishing glasses! Polarized, transitions, proper tint, wrap around, no frame and extremely lightweight! No need for any other sunglasses! I will buy them again when the time comes.
My experience with the usual luxury brand sunglasses, polarized or not simply didn't cut it. I thought I'd try Sanofan and am sure glad I did. They adjust to every light condition, enable me to see to the stream bottom, see fish and their habitat, and most importantly enable me to wade streams safely and avoid underwater boulders, logs, and other hazards. Finally, glasses that work for fishermen. I love these glasses!

True Supercharged Polarization
You see:
Polarization makes fish visible, but only high-contrast lenses allow them to stand out against the bottom.
This is "Supercharged Polarization".
In fact:
Amber and copper are the ONLY sunglass lens colors that sharpen contrast, increase resolution, and boost polarization.
They do this by cutting out the blue light that causes blur.
But here’s the real kicker:
FluidTint lenses go beyond as they supercharge polarization no matter the light.
Whether it's overcast or sunny, you’ll spot every ripple and shadow in the water—giving you the edge of a pro angler.

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.

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.
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.
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
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.
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
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.
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:
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.
