About 10 per cent of the population is colour blind and simply can't perceive as many colours as those with normal vision. There has never been any way to correct the condtion but now, a U.S. company claims they have created glasses that can open up a world of colour to users. But some eye experts remain skeptical.
Colour blindness, or colour vision deficiency, as doctors call it, is more than just a nuisance. Most with the condition can't distinguish red from green and have trouble with aspects of everyday life. They can't become pilots, firefighters, electricians, police officers or take part in several other professions.

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.
They will fix ya if’n you are left handed also, and even help to prevent pubescent blindness in young men.
It would be interesting to see more detail. Are they putting a notch filter in between the long and mid wavelength comes or are they doing different filters on each eye to allow the user to see green with one eye and red with the other?
That’s RACIST!
We need glasses that ENSURE color blindness!
As an aside, there is an optical illusion called a Benham’s top (or disk), which produces what are called Fechner colors directly in the brain, so do not need cones in the eyes to be seen.

Some years ago, it was discovered that people with total color blindness, who only see things in black, white and shades of gray, can still see Fechner colors.
They are amazed by perceiving colors for the first time, something that their brains can do even if their eyes can’t.
I spoke to a teenager in church last week who had just gotten a pair. He was amazed to see the colors in the world that he had never see or suspected were there. He wears them indoors. They look like a very slight colored sun glass. He loves them.
I remember reading an old account that in the days of B&W TV, Fechner colors could also be displayed on screen and had been used in some commercials. That might weird some people out... how is this black and white TV showing me color?
The effect does not seem to be standardized between people, or else maybe a Fechner color based color viewing system could be designed. Perhaps it could still be, but it would have to be tuned to the person.
I hate articles like this, because the reporter is either a moron, or is deliberately suppressing all REAL information.
Yes, they are using a technology that letsbthem build a die to create any sort of custom filter. So as you mentioned in your post, they are creating a notch in the spectrum where red and green response in the eye overlaps the most. They have a good video on this on their Youtube channel.
MLK would not approve.
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.
Fechner color can’t really be tuned, as it is not a fixed bandwidth, but a dynamic illusion that changes constantly.
As much as anything, the illusion it creates is based on the electro-chemical behavior of the brain, which constantly changes. Through imaging it looks like lightning within a storm cloud, darting about almost randomly.
My first thought too!
Leaves more questions than answers.
