My pair arrived in Brisbane yesterday, less than a week after ordering.
So - do they work?
In a word: YES!
They're quite dark (just 14% overall transmission), so they're intended for full daylight - not suited for indoor use. (EnChroma also make an intermediate tint sunglass lens, and a lens designed for indoor / computer screen use.) In muted light this morning (7:30 am, a bit of light cloud / mist), the effect was obvious - a lot more contrast and definition between various shades of green and red in the garden.
But as the sun broke through - WOW!
Colours became quite eye-popping - our dry winter lawn became a vivid green, pastel flowers that always faded into the background suddenly stood out ...
My partner and daughter (both with normal vision) tried them on, and were also somewhat taken aback by the sudden vividness of everything they saw, so the effect is real, not placebo.
The most dramatic difference was driving in to work - so, green traffic lights are actually green? Who knew?!
(Green traffic lights have always looked almost white to my eye, with only the slightest hint of colour, but now they are bright green. Also, for the first time ever, red traffic lights are brighter than amber traffic lights, whereas the amber has always been quite a bit brighter than the red to my eye.)
Some unexpected effects - they can give a strong green cast to some (but not all) digital displays - my Samsung SmartWatch is now green when it should be white, and there's an LED display board outside the Convention Centre which is now green, but my TV looked pretty normal (but a bit dark!), and as I sit at my computer typing this reply, the white is just white. I guess it depends on the exact colour spectrum of the RGB LEDs used.
I'll by trying to catch a spectrum tonight using my Public Lab Spectrometer
http://publiclab.org/wiki/spectrometer - I'm expecting to pick up a couple of strong "notches" in the white light spectrum.
If there are any colour-blind IIS members in Brisbane who would like to take a look, drop me a line - I work at South Brisbane, so should be able to arrange a lunch-time meet-up in the City or South Bank. (I'll be easy to spot - I'll be the guy with the cool shades examining the flower beds closely!)
