Note: Color blindness has a very large continuum, ranging from no color vision at all to very mild. As an inflicted individual, I could get a general aviation pilot's license but not a air transportation / passenger-carrying endorsement. Primary reason is that under some emergency conditions, a pilot would need to be able to see and differentiate between the red & green signal light guns from the control tower.
It will be interesting to see if these glasses can handle the wide variation of degrees of color-blindness!
I bought a pair of these enchroma $350 glasses for a friend with severe red/green color blindness. They may have helped somewhat for him to see some different hues. cant use them indoors.
I did an online slideshow color blindness test this month and can see what you are talking about with marginal conditions. I passed and was surprised to see that the test included some graphics that only had numbers if you were colorblind.
It is dang tough to be a red / green color blind engineer. You have an awful time reading graphs and usually have to remember all the numbers to get a sense of the data in a pictorial way.
Stoplights when the sun hits them just right are really tough.
