Color Vision for the Colorblind (Red-Green)
« on: March 30, 2016, 08:42:18 AM »
I will discuss this later, as I am late for work.


But if you know someone who is Red-Green Colorblind (Protanopia) there are glasses with a special filter in them that allow people to differentiate colors as most people can.


Being able to tell red flowers from green leaves comes as a shock when people first wear the glasses--but more dramatic (usually) is when people see PURPLE for the first time.


There are plenty of videos on YouTube showing people seeing true color for the first time; or even the actual color of their childrens' eyes!  It can be tear jerking, if you're emotionally labile.


Here is the main company: http://enchroma.com/


The glasses are expensive, but usually groups of friends get together & pitch in to buy their friend a pair.

When I was in college a friend offered me the summer job of painting his house. I forget which color he specified but we all knew he was color-blind, so we went to the hardware store and got about a dozen different paint sample chips (bookmark strips of paper with about 6 similar hues of a color paint on each one) and enough of a completely identical strips of a different color.

We then removed all of one exact paint sample and glued them over the original strips labelled with haf a dozen different names on each strip. Meaning, we prepared about a dozen identical but wildly differenty labelled strips.

We gave them to him and asked which one he preferred.

The poor guy kept trying to tell the difference , even took them outside for better light and was completely fooled. He finally gave in and said, "I don't know, they all look the same to me. Which one do you think?"

At that point my friends and I finally let him in on the joke and we all had a good laugh. He was a really good sport about it.

I don't see how this could work, really. If it's a filter, then how does that overcome the lack of retinal cells sensitive to certain wavelengths of light? A filter just eliminates some wavelengths of light, allowing certain ones to be transmitted through.

Color-blindness is a sex-linked trait. Males are more likely to be color blind because the gene for color sightedness is on the "X" sex chromosome. Since females have two copies of this one, and males only have one, if a male has a "bad" copy of this gene (or combination of genes, more likely), he doesn't have another one to fall back on, in the form of another "x" chromosome, like females do. A female can be color blind, but only if she gets really unlucky and has two bad copies of this gene family on both "X" chromosomes.

^That's also why balding is more common in men.

This is pretty cool... I always wondered the opposite... how color blind people see colors.

I suspect the lenses shift the wavelenghts of the light to conform to the range of colors the otherwise color-blind can see. They may not be seeing them exactly as you and I see them but they would be different enough to be seen by the door-blind. Colorblindess isn't like a black and white TV where no colors are seen, at least not usually. It is the inability to distiguish some colors from others.

Not sure is this is relevant but there are two main theories of color vision the tricromiatic theory (we have three different types of cones that have different response rates to colors. There are thee waves lengths short medium and long. The second is the opponent process theory which says that we see colors in terms of opposites meaning we see colors on a continunium. We see colors because of excitaion of one cell and that inhibits another cell. My guess is that the glasses turn the light into a wavelenth that pur retinal bipolar cells can better detect.

The technical reason for color blindness is because certain people lack certain types of cones or because the cones have the same photopigment instead of different ones for dofferent colors.

Zoops,


Here is MIT's explanation: [size=78%]https://www.technologyreview.com/s/601782/how-enchromas-glasses-correct-color-blindness/[/size]


Here's a video of a young colorblind man seeing certain colors for the first time (wearing the special glasses):



If you see the image below, color blindness occurs because some Greens and Reds have really, really similar wavelengths, only slightly different (between 550 and 580 nm).  So little difference that the mutation in the cone cells doesn't allow differentiation between the two colors.


The glasses somehow make the confusing Green color more green, and the confusing Red color, more red.


Image result for how colorblind glasses work

I always wondered if they get confused at traffic lights ... I know one is on the top and the other on the bottom but surely one would have to look twice and again on quiet streets.

My husband is partially color-blind. I love playing the "what color is this?" game with him. He got tested and it was confirmed. So far I know he can't see light greens and pinks--they look beige to him.

One of my ex's was also color-blind. As for street lights he knew where on the box they were and could tell when one was lit up.
