A Co-worker was telling me this morning about a friend of his that is Red/Green colorblind to an extend where he is not allowed to drive.
I started to think about ways that the Red/Green spectrum could be mapped into something that could be detected by someone colorblind, preferably in a low-tech,
non failure-prone way.
The idea that I came up with was a pair of glasses with one lens red tinted and one lens green tinted (like 3D glasses, only Red/Green instead of Red/Blue)
With a little practice, the colorblind person could learn "left eye - go, right eye - stop" as instinctively as the rest of us know "green - go, red - stop"
Baked?

"ChromaGen™ is a unique system of coloured lenses of a specific density and hue that are worn as either contact lenses or spectacles." - Hard to tell if this is similar to this idea or not... [scad mientist, Dec 08 2004]

i have no idea if this would work, but + for the thought if nout else. |
|

Is it really that hard to learn "bottom light - go, top light - stop"? |
|

At night, it's often difficult to see the actual housing until you're up close, making it just a light. In this case, it's impossible to tell whether it's bottom/top or left/right. |
|

This is not remapping so much as selective obfuscation. I don't know how well this would work (I get headaches when wearing R/B 3-d glasses) but [+] for the concept. |

You might as well allow blue light in to both eyes, so you'd have one violet lense (red+blue) and one cyan lense (green + blue). |
|

Even better might be to have the glasses only slightly attenuate one color in each eye, so each eye can still see everything, but green colors would be dimmed in one eye and red colors dimmed in the other. The lense colors would still be violet and cyan, but not as dark. I imagine that at first when learning to use the glasses, the user would close one eye, then the other to determine what a color is. But the brain is really adaptable. I wouldn't be surprised at all if the user could soon just look at a color and know that it was red or green. Once that happened, they'd probably just wear the glasses all the time. Unfortunately I suspect these would look funny having two different color lenses. |

Of course this sounds like such a good idea that surely it's baked already. One google search later... Wearing one red contact lense in the non-dominant eye is the cheap solution. There's another that might be very similar to this idea (see llink), but they don't give enough detail to say for sure... |
|
| |
So I'll say maybe baked, but not widely known to exist considering that neither of the two color blind people I know have them. |

Bifocals with red top green bottom would be snazzier and more symmetrical. I like! |

the red light is supposed to be the one on the side your steering wheel is on [i.e. left if you drive on the right] always for horizontal ones |
