How are colourblind people able to recognize the colours when they put on the special glasses, they have never seen those colours, right?

Anyone else with blue/yellow colorblindness fucking hate teal & maroon? Cause I hate teal and maroon.
Also I’m curious to know how many women here are CB? I am a colorblind left handed woman and statistically should have a penis somewhere around here. maybe I do and it’s maroon.
My fiancée’s family bought me the outdoor glasses. It was our first Christmas together and I bawled my eyes out in front of her family and our kids.
I put them on outside and it took about 15 minutes for my eyes to not see everything as one shade of light red. After this, I had to ask her what the colors were of several things including cars, walls of buildings, and natural things. Everything was so much more vibrant and I got chills looking at her eyes in the sunlight. The colors I already knew were so beautiful and bright, new colors like seeing red correctly for the first time was life changing.
Trying to be REALLY ELI5 here:
First, colorblindness is not just seeing everything in black-and-white.
##WHAT IS COLOR?
Our eyes have color sensors. Most people have 3 different colors sensor (Red, Green, Blue). When we look at a color, all 3 sensor are stimulated depending on the color. So, for example, we can see a lot of green, a bit blue but no red at all, and then our brain interprets that as a unique single color.
##WHAT IS COLORBLINDNESS?
There are dozens of different types of colorblindness. The most usual are when one sensor overlaps the other, that is: one green-bluish and another blue-greenish. So the sensors are kind of redundant because they will always detect almost the same thing.
##HOW COLORBLIND GLASSES WORK:
They filter out that overlapping intersection. So those two almost identical sensors will start to actually detect different colors.
They also sometimes think the colors aren’t real. My brother wore his glasses out to a public gathering in the woods, with a building for cookouts. He took off his glasses halfway through because he was convinced they weren’t working. He thought that the tacky off pink building was white, and that the glasses made him think it was pink. Blew his colorblind mind when we all told him it was pink and he realized we weren’t fucking with him
Colorblind here. Sounds like most people have explained it pretty well. I just wanted to add about my experience with the Enchroma glasses.
A local art museum was running a promotion with Enchroma where you got to borrow a free pair of glasses as you tour the museum. The only problem? The whole museum was dedicated to an exhibit by a black and white photographer hahaha. We ended up just going to the roof and having a beer while I looked over the city and looked at people’s clothes.
I’m moderate to strong protanomaly colorblind. Reds appear much darker to me. Purple always looks dark blue and light green often appears yellow. If I have a very large sample I can sometimes distinguish the colors but there is no chance if it is small (like a speck of blood looks black, or the little LED lights that flash yellow/green/red to indicate functions on electronics).
I tend to fail colorblind tests miserably. I tried the glasses and with the glasses I was able to achieve a perfect score. However, it wasn’t like in the youtube videos at all. Maybe if they allowed me to look around a bit more I would have had a more interesting effect. As it was, I passed the test, took a look around the boutique and just thought “Yeah, they’re sunglasses, nothing is in true color but it somehow helped me pass the test”. I was underwhelmed and didn’t consider purchasing them.
Maybe I’ll give it another try some day. But, to answer OP’s question. I know what I can’t see. I know purple is red and blue and I can see it in certain situations if the lighting is right and the sample is large enough. Its the contrast with other colors that is missing mainly.
Seeing colors is a bit complicated… an object isn’t red or green or blue. It’s made of material that reflects and absorbs different wavelengths (between about 380-650nm).
Now our eyes see those wavelengths by basically catching them in 3 different buckets Red, Green, and Blue. Now the only thing is the buckets aren’t side by side, it isn’t that all the light at 499nm falls into the blue bucket and all the light at 500nm falls into the green bucket. They over lap a bit so droplets inbetween fall a little into both (that’s how we can feel a teal that is somewhere between green and blue). The problem is for color blind people their buckets are a little screwed up and they overlap way too much to the point where it’s hard to differentiate between the two. What the glasses do is they actually block the wavelengths where the overlap is the strongest so you get only the light that is coming at the edges of the two buckets. It’s not perfect but it helps tell things apart.
If you just put the colours on paper and asked them to put on the glasses in a white room and list what those colours are, such person couldn’t really tell the colours for sure.
It’s more of a: I know the grass is green, I’m looking at the grass, this must be what green really looks like.
Pretty sure a lot of those videos where the person sees color for the first time and starts crying were pure marketing. My gf bought those glasses for her brother. There was no “aha” moment. In fact, the instructions say basically to keep trying them for a while and they should start working over time. They were over $300 and they got returned.
