I'm color blind as shiat and I have to wear glasses, so I really hope they release this to market soon.

That's actually a cool use for any kind of smartglasses.  I have a friend who is red/green colorblind (I think that's what it's called) and being in a car with him driving is kind of scary when he blows through red lights because they looked green to him.

Your friend is full of crap if he's using that as an excuse to blow through red lights.  I'm red/green colorblind & all it really means is that someone who is that has an INCREDIBLY tough time picking out a red item on a green fields (or vice versa).  Playing lawn darts as a kid I was always yellow or the game would be really slow as it would take a while for me to find the red darts.  Years ago my wife made a comment that she was really puzzled why I would only take pictures during the fall of yellow trees & completely ignore the (supposedly, as I really don't know) gorgeous red hillside off in the background.  Same reason.  My brain knows that leaves are supposed to be green so if there is a lot of red in there as well it all turns to a sort of muddled brown, not a very interesting picture as far as I was concerned.  I have NO problems seeing the color green nor red as long as they are by themselves, it is only when they are mixed together that the color blindness becomes an issue.

/besides, even if he couldn't see the colors as he claims, with traffic lights red is always on top or on the left, green on the bottom or right.

EXACTLY
The example I always use to explain it to someone is a cardinal in a maple tree. Until it takes off it simply isn't there.  Once it's moving I can track it fine.  I can see red, and I can see green, and tell the difference between most pairs of different greens and reds, but some pairs are a problem.

Even if you couldn't tell the difference between the red and green on lights on a traffic light - they are still pretty standard configs.  Red is on top (or on the left) - green on the bottom (or on the right).  Really isn't that difficult and there is no excuse for blowing through them.

"Cure color blindness"? Oh, come on. This "cures" color blindness the same way that a red or cyan lens does -- by blocking one range of wavelengths, while passing the other.

The Oxy-Iso and Hemo-Iso lenses are a cool idea, and more sophisticated than simple color filters -- they apparently block or enhance specific wavelengths relevant to blood color. But someone with a red-green deficit could easily "pass the color-blindness tests" by looking through one side of a cheap pair of red-blue 3D glasses.

There are a few different varieties of red/green colorblindness. Which do these glasses correct for? Cuz I'd love a pair for looking at confocal micrographs (since no one ever bothers to pseudocolor them so we color cripples can see them).

Agreed. Modern (LED) traffic lights emit very pure wavelengths of light that CANNOT be mistaken for another color. A person who is completely r/g colorblind simply wouldn't see a red light (but they still see a light!), and the green would appear blueish, as the wavelength chosen for "green" is actually on the border with blue.

Add me to to the your friend is full of crap, pile.

I'm about as red green colorblind as it's possible to be and I can tell the 'green' light from the red one. They are so far apart as to be unmistakable.

You need ImageJ (or, if you're rich, Photoshop). Do a green-blue channel swap, and you'll see formerly red-green color-coded images almost as well as a Normal Person®.

I've long wondered why so many scientific visualizations rely so heavily on red-green mappings. It's not like the prevalence of red-green deficit is new or obscure information. If you've got a single linear scale, there's no reason not to choose red-cyan or yellow-blue, or better yet redundantly encode onto another perceptual axis as well. And if you've got two scales, encoding them onto two color axes is generally the wrong thing to do anyhow.

But then Mr. Arigby wouldn't be nearly as amusing!  We're past the stage of needing baby clothes anyway.

"Hey, are these pants and this shirt the same shade of blue?"
"No, see, this shirt is that special shade of blue called 'pink'."

Boss says, "Hey, would you mind inventing a new company logo?"
"Uh... okay."
Boss F's off, wanders back a while later, and blurts, "Wow, are you colourblind??"
"Uh, yeah.  Why?"
"Oh."

maxx2112: // kept me from getting the cool high-tech jobs in the military.


Mr. Arigby was told the same thing and consequently didn't enlist.  Later found out from my bro, who isn't colourblind and did enlist, that that's a load of hooey* and that apparently the military is allowed to lie to you.  So it's just as well.

All these stories reminded me of another example.

csb alert:

Our first home was an older Victorian brick house where the bricks were painted red & all the trim was painted black.  FFWD 10 years & the paint was starting to peel & needed to be redone.

Mrs RT: "Ok, so what colors are we going to paint the house as I haven't liked this since we bought the place"
Me: "Huh, what's wrong with red & black?  I think it looks quite nice"
Mrs RT: giving me the stink eye to see if I'm kidding.  Giving it to me again just to be sure & finally decides that I'm serious. "Uh, the trim on the house is an ugly dark green.  It's really quite hideous."
Me: "Really?  Well it looks quite nice when it's red with black trim....."

I didn't have a clue & thought for 10 years that the house was a different color than it actually was.  Getting a few inches from the trim & holding up a piece of paper to cover up the red on the bricks next to it & I could then see it.  She did however agree that red & black sounded nice & a couple months later everyone else's view of the house was the same as what mine had been all along....

CSB: that's how I discovered I had a color deficiency issue. I asked why everyone kept calling it a green light when it was clearly bluish-white.

The response was, "Are you retarded?". I love that.

Anyway, I'll have to ask about these for my next eye exam. Thanks Subby!

I discovered my r/g deficiency at my ROTC physical towards the end of the unpleasantness in SE Asia. I wanted to "fly jets", so took the flight physical with a bunch of other guys. (No women in those days...too tough...no muff.) Anyway, the med tech was announcing results to the crowd and when I got to my name he announced I'd failed the medical, so I asked why. "You're color blind", he said, to the laughter of everyone in the room.

Well, I'm not color blind, but I am deficient. Oh, and I see dark green cars as black, too. And traffic lights are bluish, not really "green" (though the old-school lights were green to me...I just haven't seen one in years.)

Interesting you say that. Old school lights are green/yellow/red.
LED lights are more yellow-green/orange/red. Not a major life challenge, but requires an extra moment of focus.

A method for correcting color vision has been around for several decades. Link here: http://www.colourvision.info
The original system was patented in 1993 but unfortunately the company was not profitable and folded. Not even sure if the company that acquired the technology is still in business as their website hasn't been updated in a long time.

Wow that's a bit harsh.  I went to the USAFA, not quite as harsh as your story, but still pretty devastating.  Announcing it like that... people don't get how something so 'minor' can be quite the burr under the saddle.

"HAHA.  You just got diagnosed with a minor, but career limiting genetic abnormality.  Sure is good that you haven't devoted a significant amount of work to pursuing a career where 98% of flag officers are selected from a job you are now blocked from doing.  Oh wait, you did, and you are.  Hope you like missile silos."

Oh but don't worry, color blindness isn't considered a disability (per the gov), so it's perfectly legal to discriminate based on the condition.

The glasses I used to wear did correct my eyes so now I do not need to wear them. So technically, they did cure me of my eye issue. Then again, my eyes would cross uncontrollably when I was a kid. The glasses I had were there to stop my eyes from crossing.

kim jong-un:  Hope you like missile silos.

Perversely, SAC missile duty was about the only non-aviation specialty with any flag rank attainable...and it too required normal color vision. I was offered my choice of a supply or meteorology slot...which I declined. Besides, I didn't want to go into missiles only to spend the next 20 years in someplace like "Whynot Minot".

Oh but don't worry, color blindness isn't considered a disability (per the gov), so it's perfectly legal to discriminate based on the condition.

To be fair, they discriminated against colorblindness based on fairly sound functional reasons, unlike some of their other discriminations. I'm not bitter...well, not too much. :)
