Special filters in glasses can help the color blind see colors better

[Edit] Notes:
• People tested have all 3 cones but reduced function of one type (‘anomolous trichromats’) — either green (‘deuteranomoly’) or red (‘protoanomoly’). These are the most common forms of colour blindness.
• “All tests were performed without the glasses.” Hypothesis that the brain is being trained to compensate for the weak cones, like an audio equalizer [my analogy].
• They were testing a (patented) commercial product, in which one of the authors is invested. There may be specifics of the notch filters in the patent that were not in the paper. (I'm at work and not allowed to read active patents.)
Is that related to legal issues (as in, if you don't read patents, there's less chance that you'll end up being prosecuted if you accidentally implement something similar)?
This makes me wonder if some new colorblindness glasses manufacturer is planting "viral" content.
This is it. Last couple of rounds of these "magic glasses" have also followed the same pattern, trying to prey on colourblind people's loved ones to buy them these expensive glasses. Everything I've read from people who've actually tried this says they're underwhelming, they work by blocking some of the spectrum around where you have issues (for instance I'm Red/Green so I have issues around those colours but especially browns and purple) so you can distinguish differences more clearly.
They do NOT let you see more colours magically, just distiguish the now reduced colour set better.
I'd love nothing more than some magical solution to cure my colourblindness, when I was a kid up till I was 15 (I got diagnosed really late) my top three careers were Astronaut, Military Pilot and Commerical pilot, if anyone remembers that one scene in Little Miss Sunshine that was very close to my reality. Unforutnatly until we start replacing eyeballs somehow it just doesn't exist.
tl;dr don't buy these, they're trying to use your impulse to do something nice for someone against you.
At first I put them on and they just made everything look tinged with pink so removed them after a minute or two. Then I noticed the instructions. I had assumed glasses didn't need instructions but all it said was to leave them on for at least 15 minutes for your eyes to adjust.
My eyes did 'adjust' after a few minutes more and while it wasn't something that would make me cry like the viral videos, there was definitely an emotional reaction. I wore them on a walk through the countryside and the vivid colours of certain flowers did make me stop and I found I couldn't stop grinning.
I did find that reds look a bit orange - things like the Royal Mail van which is certainly red appeared quite bright and what I would previously have called orange. Who knows if that's wrong or right though? It's hard to know how everyone else sees things.
I don't wear the glasses day-to-day but I do take them with me if we are going somewhere picturesque.
I would caution people not to expect anything. Unless the high price of these things is pocket change for you, don't do it. Maybe find a way to demo them, or assume up front that you may end up needing to ask for a refund.
The effect depends a lot on the specific color deficiency each person has.
It became too awkward for the recipient to return it after such a fuss was made, I think (also we waited for a particular holiday, which ate into the return window). It was left with an "I'll keep trying them out", and that was that. There was a vague mention a few weeks later about how it made some flowers maybe look a tiny bit different, but if there was any real effect it was not significantly life enhancing for this person, and certainly not worth all the hullaballo or expense.
While I get that a lot of these videos seem like viral marketing, I know from personal experience in this case that it wasn’t. They really do work for some people, and it’s an amazing experience for them.
n/m I got the full message during one of the pans and then the voiceover confirmed it.
I find that shirt incredibly hard to read and I don't _think_ I'm color blind but maybe I am slightly?
The result for me was: DEUTAN with MODERATE severity
The description they provide for this type of color blindness fits exactly with my life experience.
>"WHAT IS DEUTAN COLOR BLINDNESS?
Deutan color blindness (also known as deuteranomaly) is a type of red-green color blindness in which the green cones in the eye detect too much red light and not enough green light.
As a result, red, yellow, green, and brown can appear similar, especially in low light. It may also be difficult to tell the difference between blues and purples, or pinks and grays."
We went for a walk in the countryside and he was still (a couple of weeks later) excitedly pointing out how many different colours were in the field.
It wasn't quite the viral marketting thing, but I was surprised and impressed by how much difference they seemed to make to him. I guess it's quite person specific though.
As many of you know, the western US has been experiencing significant wildfires in recent years.
When the smoke gets particularly bad in the valley I live in, the one upside is that colors -- particularly red become much more vibrant -- I marvel at stop signs, stop lights and naturally-occurring purples, in particular.
It makes it seem as though not only can I distinguish, but my perceived color spectrum widens. I swear I can see the colors clearly as they should be, even though I lack whatever cones or rods required. While I don't react to it with crying in the videos, it's certainly stunning and emotional.
I've been working on software over the years to try and duplicate the effect using a phone camera. It doesn't seem to be a simple brown filter.
As a kid, my parents took me to try out a pair (maybe 25 years back)... but I just didn't like it. Everything seemed so much more colourful, and bright. It was almost like sensory overload.
Everything was also more confusing; I didn't actually feel like I could differentiate colours any better - colours were different, sure, but I still didn't know what they were.
I decided not to use the glasses and since my vision wasn't that bad I stumbled through. I realize as an adult now if I had just waited I likely would have acclimated to the situation.
Then again, when I finally did get glasses, I refused to wear them more than a few minutes a day for my first month. They just made me uncomfortable, visually and mentally. It seems like people are always most comfortable with what they know, even if it's objectively worse.

As expected, I am not colour blind, but if you are not sure, give it a go!
Here is one example (via invidio.us): https://invidio.us/watch?v=XSD7-TgUmUY
Edit: Just read in this thread that they may be viral marketing, and the glasses are not as special as they are expensive.
Not sure what it has to do with anything.
However, if the glasses allow you to start differentiating colors that you previously perceived as a single uniform color, then I think there is a much stronger reason to wear them.
My father is red-green colourblind, so I've seen some consequences of it. I consider it a disability (there are ordinary things my dad just can't do), but it doesn't require fixing.
To most people red and green are as different as black and white; imagine having trouble distinguishing black and white, and you'll have an idea why some people think you might want these glasses. (Yes, I'm making assumptions about your vision here that might not be correct.)
Very sad psychological defensiveness for your in-born lesser function. "Naturally", my vision is poor enough that I would be completely unable to drive, watch TV, and barely able to read or use a computer without glasses, but if I were to call optometrists and my parents who wanted to give me the full function and opportunities that other humans have discriminatory and evil for giving me glasses, I would definitely be displaying some unjust ego defense.
When the world has been out of focus your entire life, and a pair of glasses suddenly makes it snap into sharp focus, it is nearly indescribably overwhelming. However, it absolutely means I can do jobs I would not be safe doing otherwise (operating machinery, driving, etc.). This type of discrimination is justified for the safety of others. If you have the right type of color blindness that glasses such as these could help, then you _can_ learn and adjust to more proper colors, if you are willing to do so, just as I could adjust to the way the world looked utterly suddenly changing. Just don't be so stodgy and defensive.
