Glasses provide cure for colour blindness

Scientists have developed special spectacles that allow someone to see in the full spectrum of light.

The glasses are aimed at people who suffer from red-green colour blindness, a genetic abnormality that is thought to affect up to 10% of men and a small percentage of women. The spectacles were originally developed for the purpose of increasing the ability to see oxygenated blood in the skin but it was later found that they were also able to help people with colour-blindness see in the full range of colours.

"Most mammals - your dog, horse, bunny - have two dimensions of colour," said evolutionary neurobiologist Mark Changizi. "A yellow-blue dimension, and a grayscale (or brightness) dimension. Some of us primates, however, have an extra dimension of colour vision: The red-green dimension."

"The high tech glasses help those with "red-green deficiency", an inability to see some red and green colours."

Now if they'd just devise a cure for "beer goggles"

Heh, the cure for beer goggles is not to put them on in the first place I think this is pretty neat, though I don't know how I would feel about an improvement of red/green at the cost of losing some blue/yellow.

My brother has "color blindness" I do not. I guess I can't imagine what he's missing, in the sense that I can't really show him.

Fascinating! I want to try these - at that price they are worth investigating. I have mild red-green color blindness (deuteranopia) and yes, it's hard to describe to someone without it, just as those with 'full' color vision couldn't describe how much better or different their worldview is. But I'll try.. First up all bright blues, oranges and yellows are just as beautiful, colourful, dazzling and easily recognisable to me as they are to you non-CBers. - dark reds are not vivid to us, and may be mistaken for dark browns or even dark greens - dark blues may be mistake...

I am always amazed at the serendipitous results of experiments intended for one purpose that have sometimes better results when applied to different purposes ... Penicillin, for example.

Would be interesting if they started seeing things we couldn't, like ghosts or something. I really want ghost glasses...

Interesting, red-green color blindness runs in my family. Me and my 2 brothers are red-green color blind. But I can't really see the appeal of these glasses. In my case, it's not like I'm going to get run over crossing the road because I can't tell the green man from the red man at the crosswalk. It's quite subtle. Can't do them damn color blindness test for hell though. There's a number somewhere in that blob of coloured circles? Yeah, whatever! I have a brother however who has it worse. He's an arty type and I remember as a kid him drawing pictures with li... [More]

That's fascinating - it sounds as though like me, you would also be classed as a deuteranope, but the effects are significantly different - there is obviously a wide range of differing sensitivities in differing color bands.. Like you, I don't encounter many problems with it either.. but I read some comments from CB people who had tried these glasses and were quite impressed - so now I just want to see what they do.. I guess I have visions (geddit?) of it being an epiphany, like the first time you put on a good pair of Polaroids (preferably the slightly amber coloured ones, on a very... [More]

Probably because you don't realize what you're missing.
