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.
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
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.
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.
