Hi List Members
I’ve been keen to support our color vision deficient [CVD] photography students that we get through our doors at Massey University.
In the past I have sort the help of people on this list in that regard. (thanks for that help!).
Recently one of our CVD photography technicians pointed me to the ‘en-chroma’ glasses web site. See.. http://enchroma.com/
The science behind the glasses seems logical. As far I understand it they use interference filters to notch out specific spectral bands. To increase the channel separation of the M and L cones in the eye of CVD people.
the technology works with some anomalous trichromats. But they don't work with true dichromats. Apparently about 80 % of CVD people are anomalous trichromats.
see.. http://enchroma.com/technology/
Looking at the video posted by some of the CVD people trying the glasses on for the first time, they seem to be very effective for some.
We have ordered some of these glasses to be held at our photography department, so that any of our CVD students on campus can at try them to see if they benefit from them.
Some links to videos of CVD people trying on the glasses for the first time...

A Colour Monitor for the Color Blind?
The full strength en-chroma glasses are too dark for indoor use, let alone looking at color on a monitor.
But En-Chroma make a lower strength lenses that transmits enough light to look at monitors with. But the effect is not strong with that lens.
But I was wondering, in theory at lest, with narrow-band LED’s, would it not be possible to re-shape the spectral output of a color display so that a monitor could have the full en-choma glasses effect directly for CVD people… . But without the glasses ??
And could it be somehow made to work with normal trichromat people too?
your opinions and thoughts appreciated.
regards
Peter
