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