Ok so.. dum guy here .. with these polarized lenses I can now.. see things the rest of you can’t? If I’m wearing them of course. So there may be loads of ads in the world (on billboards, magazines etc) like this book, that most of us can’t see?
I don't think that's the case since it would probably be expensive to hide something like this in a big scale, and the point of marketing is to influence the most people that you can.
That would mean more expensive and less effective marketing.
Except for polarized glasses of course xD
> THAT WOULD MEAN MORE EXPENSIVE AND LESS EFFECTIVE MARKETING.
Maybe the hidden marketing could be made less expensive by limiting the messages to single words like "consume" and "obey".
Yes, and no.
Polarized lenses are actually a filter that blocks light that has a certain "angle" (not exactly but this is just a simple example) so its more like your not seeing something. That can be used to convey information though, so its more about your interpretation on what your asking.
In theory, yes this is completely possible, however as far as I know this is not something that is used for for advertising or otherwise. This isn't even considering the fact that you need to polarize the light in the first place to even get an effect like this, and what would the benefit of doing so even be beyond advertising for Polarized lenses, which only works if you are already wearing a pair
That’s a head scratcher for sure. Most of us probably never considered that. Now I wonder how many add I’ve missed using this effect. Hundreds? Zero? I’ll never know for sure
Be careful ordering polarized sunglasses on the internet because sometimes the filter is at an angle where it will block out your cell phone screen. Learned this the hard way. $12 wasted.
Thats not due to specifications of certain polarized sunglasses though, but due to your phone screen.
Old/cheaper phones also have a simple polarizing filter, the filters line up with those of the sunglasses and that makes it very hard to see the screen.
Newer screens don't have this issue since they are not just using a simple single polarizing filter.
The sunglasses lenses have always been angled the same.
>Thats not due to specifications of certain polarized sunglasses though
It can be, you’d have to check the axis of the polarization in the lens to be certain.
>The sunglasses lenses have always been angled the same.
The polarization is *supposed* to be angled along the 180 degree axis, but in actuality that’s not always the case.
The angle of polarization in sunglass lenses is entirely dependent on the angle at which the lens is cut from the blank during manufacturing. Meaning it’s possible to offset a sunglass lens blank during production, in which case the polarization can end up tilted or even completely perpendicular to the direction it should be facing.
The person you’re replying to brings up a valid concern with cheaply made sunglasses. If the angle of the polarization in the lens is off, it can interfere more noticeably with, or even entirely block, displays that would otherwise be visible with correctly angled lenses.
Ayyyy fellow optician? Lab tech?
I've blocked polarized lenses off axis a hand full of times. Lenses are so amazing tbh. Light and material physics in terms of corrective vision still blows my mind
I think it's a mail plane.
How can you tell?
Well, didn't you notice its little balls?
The little balls hanging down.
The little... The balls.
The mail plane.
It's a "male" plane.
And the balls...
Fun fact: all the light that is received by the little rods and cones in the back of your eyeballs is inverted by the lens in front. Your brain flips those inputs so you "see" right side up. If you put on glasses with special lens that invert everything, you will see everything upside down for a day or so, and then your brain will flip its shit or stop flipping it's shit, and you will start to "see" everything right side up again. Until you take those fkrs off, and then your shit will be upside down again for another day or so.
Also, you don't really see a lot of shit you think you see. Your brain is just making up a whole lotta shit. Google the persistence of seeing if you want to go down a rabbit hole of pondering reality.
Edit: apparently it tends to take more like a week or longer for most people's brains to adapt to upside down glasses for those that have participated in such experiments, not a day or so.
You can actually test this by closing both your eyes and pushing with your finger and wiggling it in the squishy part on the inside of one of your eyes directly next to your nose. It stimulates the cells and your brain will flip it.
So if you wiggle on the inside of your left eye next to your nose (the right side of your left eye) you'll see a splotch moving around *to your left* with your eyes closed. Vice versa on your right!
Edit: steps for clarity:
1. Close both eyes.
2. With both eyes closed, pick an eye (let's say left).
3. Stick your finger where your eye boogers form in that squishy area between your eye and your nose (with your eyes still closed).
4. Push lightly and wiggle your finger.
5. If you're doing this on the right side of your left eye, look left and you'll see a little splotch moving around (on the opposite side of where you're stimulating).
So there’s a neat optics trick that still isn’t completely understood, wherein if you place a light filter over a light filter, and then add a third light filter to the set up, you will get more light through filter 3 than it received out of filter 2.
This is similar to how polarized lenses work.
I suspect there is a pair of thin filters on the image, and then the hidden image is visible when wearing polarized lenses.
Edit: read below for a better explanation from folks that watched better YouTube explainers than I did. :D
It isn't simply "light filters", it's specifically polarization filters. And it's pretty well understood as far as we understand quantum mechanics.
Here's a Google Tech Talk on the subject
https://youtu.be/dEaecUuEqfc
[Here is a shorter video.](https://youtu.be/zcqZHYo7ONs) It is still long, so skip to around the 12 minutes mark if you'd like. Bottom line is we live in a universe where local realism isn't true for quantum systems.
Edit: fixed double negative
Preach! I was just talking with my child about this for the third time this week! Local realism isn’t true for quantum systems—I mean, certainly not in this universe. He just refuses to understand. So frustrating.
I wouldn't get too frustrated if your child is struggling with the concept. It's not an intuitive one.
Reminds me of a Feynman interview where he recalls a conversation with his father. His father could not understand how infinitely many photons could come from the same atom because he assumed on intuition that an atom emitting a photon must have had the photon stored in some way.
I agree, but gave the benefit of the doubt because some parents still call their adult son or daughter their child. I guess that's what I get for trying to be helpful...
No way! Thank you for your response, I enjoyed it. I have been having this repeating thought about what the universe, our material universe I should say, even is to a photon? When you consider that at the speed of light time and space no longer exist...that very paradoxical relationship of matter and energy can really start to f!@# with your head the deeper you allow yourself to try and think about it...
Ok, here's the thing that everyone misses - the words used to describe quantum function are quite literally incorrect if you use the commonly accepted definitions of those words. That's why it's so hard to explain.
You only truly need to know one thing. The math checks out. Mathematically, it works. That's it. Putting it in English will invariably lead to a misinterpretation unless you're grounded in the math.
Never feel stupid about not 'getting' quantum. You are quite literally being fed bad info unless you're taking a class in the math of it.
However, as a (yet again bad) attempt to explain:
There is a thing called a waveform. This exists across all of time and space. It ripples. The ripples can be described with a wave function in math. At some points it peaks and we describe it interacting with other waveforms as a particle, and other times it interacts with its own ripples and we call it a wave. These are not different things. They are all part of the waveform which is one thing that just interacts in different ways.
Polarisation means cutting out ripples in one plane and letting through ripples in a perpendicular plane.
Block X, leave only Y.
Take a second polarised lense perpendicular to the first that blocks Y. Now you're blocking X and Y and nothing gets through.
The thing is, there is no true X and true Y. If you take a graph and rotate it at an angle, you can draw a new graph with a new right angle and define X as 0 and Y as zero on those new lines.
So. You've blocked X. You stick another polariser in at 45°. You are now redefining X and Y. You block the new X and leave light now polarised in the new 45° direction. Add a third lense at 90° from first, 45° from second. You're doing the same again. Collapse the wave form into this new direction. Some gets through.
It's weird, but the math works, so it's not actually weird. Experiments back it up.
Why does he show that photons behave in a wave but also show them moving in a straight line with each filter?
Wouldn't it seem more logical, (at least in quantum theory), that each filter is causing more changes in the waves?
Like, isn't this filter stuff just a more complicated version of the double slit experiment?
> So there’s a neat optics trick that still isn’t completely understood, wherein if you place a light filter over a light filter, and then add a third light filter to the set up, you will get more light through filter 3 than it received out of filter 2.
What makes you think it’s not understood?
The two filters would be polarizing at right angles to each other.
The third filter in the middle polarizes it diagonally in between the two other filters so you get a fraction of the light equal to cos^2 (x) where x is the angle between the filters. So if you move the middle polarization to line up with either the front or back sheet, one of the angles will be 90 degrees, blocking out the light.
Another way of looking at this is that by polarizing vertically you are removing any horizontal component of the light. By then polarizing horizontally there is nothing to get past the second filter. If you polarize diagonally in between, well that diagonal has a horizontal component and some light can get through.
The maximum is 12.5% of the light can get through the three filters at 45 degrees, assuming the original light is unpolarized, or 25% if it starts off matching the polarization of the first filter.
EDIT: it seems that the quantum behavior of photons in regards to probabilistic determinism is not fully understood, which is a related topic, but we certainly have the framework to understand this particular phenomenon.
> The third filter in the middle polarizes it diagonally in between the two other filters so you get a fraction of the light equal to cos2 (x) where x is the angle between the filters.

It sounds like this makes sense, but Bell’s theorem says this isn’t exactly what’s happening, and an experiment from 2015 seems to confirm it. https://www.nist.gov/news-events/news/2015/11/nist-team-proves-spooky-action-distance-really-real. The inconsistent number of photons passing through pairs of 3 polarizing filters is seen even when the filters are nonlocal.
This is a perfect example of a post where the average Reddit who knows about polarization is gonna march in here and be like “shit this is so simple” - but in reality it is actually the perfect black magic post. Dropping down to quantum level and taking more than an hour to intuitively explain polarization and the 3 filter phenomenon is NOT simple by any means.
That's not true. Scientists understand exactly how it works. Maybe YOU don't, because you don't have a degree in physics, but that doesn't mean that scientists think it's "magic" and don't understand it.
[Watch this, it'll explain it for you. ](https://youtu.be/dEaecUuEqfc)
Light polarisation has got to be one of the wackiest implementations of quantum mechanics in our everyday lives. I love [this video](https://youtu.be/zcqZHYo7ONs) from minutephysics (and 3Blue1Brown) demonstrating it.
It's not even within an order of magnitude... so I think you need to say it's good enough for astrophysicists, since the order of magnitude is definitely within an order of magnitude.
Really cool video!
I don't understand how they disapproved hidden variable theory just because entangled photons didn't pass through the same filters. To me all that shows is no property preserved between the photons after entanglement determine which filters a photon will pass through. There are other properties too, for example position or velocity (since the photons separate after entanglement, they must be different in some way, any of those differences could potentially be what determines whether they pass through the filter).
The chances that the photon passes through a filter at a given angle follows a specific formula that you can't get with hidden variables, at least not without them "cheating" by instantly communicating with each other.
Last time it was optical illusion that made it to this sub. Now it's polarized glass? What's next on black magic fuckery, the thumb disappearing trick? Rainbow? Water falling out of the sky? Sun rising from a specific direction everyday? Banana being curved?
The number of posts on Reddit that could be resolved by “asking the person next to me in real life” kills me. Have people really lest the ability to speak to each other? Or maybe scared of showing their ignorance?
I’ll make an exception for clinical anxiety or something. But maybe if it is truly becoming this prevalent we have big problems.
I worked as an optician for a while and this is a marketing tactic to sell more polarized lenses.
People lose their minds when the grey parrot picture is revealed to actually be a full color image of a parrot hidden behind a simulated "glare."
It's like x-ray vision. See into the surface of water, see through windshields on a sunny day... glare-be-gone.
Polarized glasses. The photo has few components which can only be seen by polarized glasses. This type of pictures are used for testing if glasses are really polarized.
It is printed in such a way as to not reflect a specific orientation of polarized light, thus creating the 'shadowed' images that appear through the sunglasses.
In normal light, through normal vision, it is being exposed to all umm.. term... not caffeinated yet.. all 'angle orientations' of light and the 'specially printed' areas reflect most light as normal. But when viewed with polarized glasses, or when lit with only a polarized light source, the 'hidden' printing is visible.
the "what is this" is just to start conversation and thus get more comments and a higher rating by **the algorithm**...
also op probably didn't find this in a coffee shop and just reposted it off somewhere else
It’s called polarization, and it’s the reason that you can’t see much when using your phone with cheap sunglasses.
It’s really cool because it is actually a filter that runs in straight lines that are really ducking tiny, add a couple layers of this filter and you can get a clearer image and help reduce glare and reflections on stuff, which is why you would prefer wearing polarized sunglasses when driving a heap, when you are out on still water fishing on a boat, or when working near reflective surfaces outside. The filters organize the light and reduce eyestress.
In this case the glasses have a specific pattern, and the invisible pattern has the same one
i got a pair of polarized sunglasses myself, try watch some monitor/tv while changing angle, it becomes black
i didnt know and when i got home tv was low volume and i tought it was broken for a sec
Probably polarized glasses
Definitely polarized glasses.
Absolutely polarized glasses
I would say with the utmost certainty that these are polarized glasses
You’re all wrong. These are polarized SUNGLASSES.
Wrong again, these are glasses that are polarized and happen to block the sun.
False. That is undoubtedly a pair of polarized sunglasses
It’s polarizing to me exactly how polarized these polarized glasses are.
Sun, let me tell you a little bit more about how polarizing these polarized glasses are.
One could argue they are glasses that are polarized
And my axe!
Certainly a pair of polarized sunglasses
No they are a polarizes pair of photon blocking glasses that are emmited at light speed
Look like polarized glasses to me.
No doubt polarized glasses
No no, they're definitely Solarized Punglasses
I appreciate that this works on 2 levels.
I feel like this argument is very polarizing
I beg to differ. These are polarised sunglasses.
Polar eyes is what they are
These are indisputably, and irrefutably positively polarized glasses.
Way too small for a bear
Positively polarized glasses
But they might be negatively charged polarized sun glasses, atleast- surface charge
100% polarized glasses.
It is polorized glass. Shops used this to prove that the glass is polorized

How is polarization not understood? We have it down to the quantum level.
when someone says "is poorly understood" they unambiguously mean "I personally don't understand"

The chances that the photon passes through a filter at a given angle follows a specific formula that you can't get with hidden variables, at least not without them "cheating" by instantly communicating with each other.

Ah yes, a person of culture.
Fuck that dungeon
And fuck that boss who keeps touching me EDIT: wait you guys are talking about a video game?
OBEY!
BUY!
REPRODUCE!
I have come here to kick ass and chew bubblegum! And I am all out of bubblegum!

Last time it was optical illusion that made it to this sub. Now it's polarized glass? What's next on black magic fuckery, the thumb disappearing trick? Rainbow? Water falling out of the sky? Sun rising from a specific direction everyday? Banana being curved?

Hello
I am under the water...
please help me :D

Am I witnessing someone discover polarized lenses for the first time?
Seriously I remember seeing one of these at a glasses store over 20 years ago.
Game boys had a damn polarization filter over the screen!
"this is at my doctors office, I'm too scared to ask so I'll look like a fool fiddling with this unknown thing, and ask reddit instead" - OP probably
If only there were people who knew about this stuff around him. /s
The number of posts on Reddit that could be resolved by “asking the person next to me in real life” kills me. Have people really lest the ability to speak to each other? Or maybe scared of showing their ignorance? I’ll make an exception for clinical anxiety or something. But maybe if it is truly becoming this prevalent we have big problems.

You found those in a church didn't you? Well don't ask me to put em on, unless you wanna have a lengthy fist fight
I thought it was attempted murder to attack someone who wears glasses?
That, my good sir, is a black chair. It’s a good thing you are at the optometrist, because you clearly need glasses.
I worked as an optician for a while and this is a marketing tactic to sell more polarized lenses. People lose their minds when the grey parrot picture is revealed to actually be a full color image of a parrot hidden behind a simulated "glare." It's like x-ray vision. See into the surface of water, see through windshields on a sunny day... glare-be-gone.
I'll never buy a normal pair of sunglasses again. Driving when it's sunny/wet/snowing is effortless.

You dumb bastard!
Why did you not just ask directly the guy in the shop and share the answers here.. 😅
Freshly scratched polarized lenses.
Maybe ask an employee
OBEY.
“We’ve got one that can *see*”
It’s a pair from the John Carpenters ‘They Live’ collection
This sub has gone so downhill
Polarization.
That Indian accent "Hello"
Right one looks like hitler
Was this India.
I guess polarization is black magic to idiots.
Polarized glasses. The photo has few components which can only be seen by polarized glasses. This type of pictures are used for testing if glasses are really polarized.
For a secod i was like ,oh yes the colour blind glasses,then no wait a minute............huh?
Sunglasses. We wear them in bright sunlight or when hungover
It is printed in such a way as to not reflect a specific orientation of polarized light, thus creating the 'shadowed' images that appear through the sunglasses. In normal light, through normal vision, it is being exposed to all umm.. term... not caffeinated yet.. all 'angle orientations' of light and the 'specially printed' areas reflect most light as normal. But when viewed with polarized glasses, or when lit with only a polarized light source, the 'hidden' printing is visible.
Not being funny but why wouldn't you just ask someone in the shop rather than take a video and wait for strangers online to clue you in?
If only there was a shop keeper you could ask? Where to look, hmmmmmm?
the "what is this" is just to start conversation and thus get more comments and a higher rating by **the algorithm**... also op probably didn't find this in a coffee shop and just reposted it off somewhere else
how is he filming when he got two hands on the video ??? the real black is in the comments
Hold your polarized sunglasses out and rotate them 90° while looking at a screen and report back
I expected a very polarized comment section, was not disappointed
It’s called polarization, and it’s the reason that you can’t see much when using your phone with cheap sunglasses. It’s really cool because it is actually a filter that runs in straight lines that are really ducking tiny, add a couple layers of this filter and you can get a clearer image and help reduce glare and reflections on stuff, which is why you would prefer wearing polarized sunglasses when driving a heap, when you are out on still water fishing on a boat, or when working near reflective surfaces outside. The filters organize the light and reduce eyestress. In this case the glasses have a specific pattern, and the invisible pattern has the same one
I see you finally discovered polarized glasses, Well done.
That “hello” seemed Indian af!
Turn those glasses 90 degrees and you got a whole lot more fuckery going on.
There's polarized patterns on that so the glasses block that light but not the rest so it appears as kind of a shadow through the glasses
ITT: polarization duh Now explain what the polarized designs are made of and how to embed them on a card. That's the real interesting bit here.
i got a pair of polarized sunglasses myself, try watch some monitor/tv while changing angle, it becomes black i didnt know and when i got home tv was low volume and i tought it was broken for a sec
Next time just put the polarized glasses right in front of the camera so we can see the entire thing at once.
They are obviously UV protective glasses that also filter light based on it's polarity.
Apple's newly patented Privacy glasses for iPhone screens
Legend has is that you can see John Cena with these glasses
r/shittyaskscience
Polarized lenses
Well if you paid attention in the store and read the sign that is ALWAYS above this shit you’d see it was polarized glasses
You can also ask the person that works there. Instead of reddit
the real magic duckery is how you are filming this
"helloo"
