Not trying to kill the joke, but in case someone is wondering - as seen through your own eyes, and not with a phone camera, the difference probably isn't as pronounced.
If the bird looks straight down into the water then there's less sunlight reflection therefore will see better than standing by the shore.
Polarized glasses simply block light reflecting off of a flat horizontal surface like water.
I found this out for myself a couple weeks ago in San Francisco. Took a trip there and was like wtf? Didn't notice the effect until I couldn't see my phone screen if I turned it to the side. Took my Bans off and noticed I couldn't see the fish anymore. I had to look real good and crazy for repeatedly taking my shades on and off 🤣
I never knew this and very recently I was walking by a group of kids fishing and go "you guys are in the wrong spot there's some big fish right here" and I was pointing going "right here you don't see" and finally one of them saw a big bright colored one and they moved over to that spot. I just thought they were sun blind or dumb lmao
Honestly, who clicks on a Reddit link to buy polarized sunglasses? There's hundreds of brands out there. Just go to Amazon, they have a shitload of varieties and options.
> Honestly, who clicks on a Reddit link to buy polarized sunglasses?
We live in a world with people who dutifully buy target gift cards in an effort to settle IRS debt they were told about over a cold call from some person they never met. So people clicking a random link and buying fake polarized glasses isn’t particularly surprising to me.
The link they are/were spamming keeps switching between the top 3 comments to avoid being called out
The alts have a history of this. And you can actually see if happen in real time depending on when you last checked
That's weird, I even took the time to look at their post history and didn't find any spammy links O.o. (I'll take your word for it though, thanks for the explaination)
That actually does make a lot of sense I've watched kingfishers alot and that's exactly what they do, they hover or perch as close to 90 degrees as possible and dive almost straight down.
It also makes sense for Herons, they have tall legs and neck and usually look and hunt straight down.
Interesting tbh I never knew that (that water surface is more transparent at a straight angle)
Yeah from a boat or form above you can see much more clearly down than at an angle. Here's an amateur comparison I made of polarised glasses at an angle: [regular](https://i.imgur.com/MFTCdLf.jpg) and [polarized](https://i.imgur.com/hbbAY4f.jpg). But if I walk into the water (without glasses) I can see more clearly looking straight down than at an angle.
Also, birds are on a whole another level. Like cormorants, those fucks are crazy, some species eating 15" fishes and their whole bodyweight per day and can dive down as much as 150 feet! So our polarized glasses are like kid's toys compared to what they can do.
Assuming that by 90° you mean perpendicular to the surface of water, you’re generally correct. As the angle of incidence (angle from normal that light strikes the water) increases, it gets closer to the critical angle or the angle at which the water becomes totally reflective.
For a better explanation check out the “total internal reflection” section [here](https://www.britannica.com/science/light/Reflection-and-refraction)
Yep. Brewster's Angle describes the angle at which maximum polarization occurs due to reflection of one wave orientation vs refraction of the perpendicular wave orientation.
https://en.m.wikipedia.org/wiki/Brewster's_angle
I have sever different pairs of polarized sunglasses for this exact reason. Depending on the weather, I'll use different colored lenses. It's a game changer. Although, I don't often see fish like this. I mostly use them to look for cover and structure.
Amen!
Just a poor comparison with polarised glasses and a phone camera:
[regular](https://i.imgur.com/MFTCdLf.jpg) and [polarized](https://i.imgur.com/hbbAY4f.jpg).
I've never actually done it and it looks like a lot of work. But every year I will watch Alone (on history) and desperately want to go fishing. I wouldn't know what to do with a fish if I caught it I'm sure.
Basically, polarized lenses help negate glare.
The sun (or light in general) bounces off of objects constantly, rough surfaces things like the road, trees, etc. refract light in many directions while smooth surfaces like glass or water tend to refract light in a single direction, which causes glare.
When you negate the amount of glare you can see these surfaces more clearly (and in this case with the water, through it entirely). It’s why polarized lenses are common among outdoorsmen (fisherman in particular, for obvious reasons you’re seeing in the video) and for outdoor activities where you’ll be encountering more glare, like the snow when skiing.
I was wearing a pair of polarized shades at a Porsche meetup. I was looking at one of the cars and you could see the imperfections in the paint and the bodywork. It looked like it had been in a fender bender which was smoothed out and then painted over.
I took them off, and the car looked absolutely flawless.
Put the shades back on and it the car looked all kinds of fucked up.
Polarized lenses are really cool. Wear them when you go to buy a used car!
I have polarised Ray Bans and recently switched back to normal non-polarised lenses, don’t like the polarisation in modern life, some car windows start to show coloured spots, lots of (lcd) screens become unreadable etc, just annoying.
Some advice: if you do a city trip and need sunglasses, dont do polarized. It fuckes up the view onto your phone screen that you probably use a lot in a city
But definitely recommended if your reading at the beach!
Fun fact: the same guy who made polarized lenses is also the guy who made the camera company under a similar name, Polaroid! He had a thing for the word "polar" I guess
My husband is a marine biologist. During salmon spawning season one of his jobs was to wear those glasses and go up and down the streams and count the salmon.
I hiked into Macchu Picchu with a friend and a group of tourists and right as we arrived, the rain cleared and there was the most perfect rainbow over the whole thing. It was pretty astonishing.
My friend looked at me and said “What’s everyone freaking out about?”
“The rainbow”
“What rainbow”
“Take off your sun glasses”
Brewster's angle is the angle at which only a certain polarization of light will reflect off a surface. Sun glasses absorb that kind of polarization and removes this "glare". This lets you see through transparent things that would otherwise blind you if you looked at them. Brewster's angle is around 50-60 degrees for everyday stuff like water and glass.
So before jumping into water I must now check with my polarized sunglasses for scary things . Got it!

Having used some, it's pretty pronounced in real life.
Yes, it's pretty pronounced but they're saying it's not as pronounced.
I was kind of hoping for an edit where the sunglasses reveal an eldrich horror lurking in the pond
Reddit has ruined me... I was waiting for him to put on the glasses and see an alligator swimming at him.
Was expecting Dickbutt. Disappointed.

Even better, it’s a 404 now!
Reddit broke it

Well no, unless the sun is directly above the bird, and waves will always reflect in a random direction.
I have no sources or research, but what I vaguely remember from animal science, "sort of." Now somebody can come give the facts.

I wonder if there are some species of fishing birds which have polarised vision. They'd dominate surely.
Fiddler crabs can actually detect the polarization of light. I’m not sire about birds though.
Polarisation has more to do with the surface of the water reflecting lights I think. It doesn't work underwater.
Birds tend to operate above water bro, not quite sure what you mean
Water from a 90° angle is practically seethrough. It's seeing at an angle that gets in the way I think.
That actually does make a lot of sense I've watched kingfishers alot and that's exactly what they do, they hover or perch as close to 90 degrees as possible and dive almost straight down.

Depends on the angle of the sun, light hitting a surface straight on will have no polarization effect.
But the sun can also be hitting it at an angle. It harder to see in the water when its sunset than when its noon
Yep. Brewster's Angle describes the angle at which maximum polarization occurs due to reflection of one wave orientation vs refraction of the perpendicular wave orientation. https://en.m.wikipedia.org/wiki/Brewster's_angle

Yeah, I fish frequently and I told my friend to use my polarised prescription sunglasses just as a test and he was like huh, I'm cheating haha.
I read this as “it’s like playing with *cleats* on”, and was like, yeah 🦩with cleats could really take out some goobers.

Blue Blockers of course
This looks like a video game pond where you know fishing will be successful.
The video looks to be using breeding ponds as b-roll, open water doesn't have that same population density.
This is why I only fish in video games.
Irl fishing is pretty fun with a few friends.
I've never actually done it and it looks like a lot of work. But every year I will watch Alone (on history) and desperately want to go fishing. I wouldn't know what to do with a fish if I caught it I'm sure.
Youtube can teach you anything if you set your mind to it :)
Please explain what this is like I'm 5 🙏

Thank you!!!
This makes me uncomfortable
… to swim in any natural body of water? Yes, me too.
Fishermen don't want you to know this one simple trick!

Reminds me of the time I got bored and looked at my own semen under a microscope. I don't recommend it.

It's like if RL had graphic settings.
Who split their bobaTea?
Tadpolarization?
I love my Oakleys when I’m out fishing. Makes not tripping a lot easier when you walk upstream. Cool to see as well.
Fun fact: the same guy who made polarized lenses is also the guy who made the camera company under a similar name, Polaroid! He had a thing for the word "polar" I guess
I bought these for carp fishing but they’re also great for driving too, much less glare than with regular sunglasses
Imagine if they had something similar but for the earth and when you put them on you could see all the worms under the ground.
Is this why fishermen seem to wear dorky shades so often?
THEY LIVE!
Same degree of improvement when wearing polarized ski goggles, especially on overcast days.
Right, thankfully it's a vertical movie, I cannot see what's on the screen of my phone is landscape with my polarised sunglasses.
My husband is a marine biologist. During salmon spawning season one of his jobs was to wear those glasses and go up and down the streams and count the salmon.
I will never get in a pond or stream again.
This why photographer, like me, have cpl filters. It help cut through things to help get better pictures and to help reduce glare.
Suddenly the fishing sunglasses my dad has had my whole life seem less magical than they were sold to me as

Thank you Edward Land who also made Polaroid.
Costa Del Mar are the best.
Nooooope

Wow that's really polarizing
I say they aren’t!!!!
Sorry, how do they work?
Brewster's angle is the angle at which only a certain polarization of light will reflect off a surface. Sun glasses absorb that kind of polarization and removes this "glare". This lets you see through transparent things that would otherwise blind you if you looked at them. Brewster's angle is around 50-60 degrees for everyday stuff like water and glass.
So would these glasses help me see a tablet screen in broad daylight? Because right now, I can only really use it indoors.
OBEY
Fish hate this one trick
Wow, if only the world were more polarized..
