According to their test, I am a "strong pro-tan" and an unlikely to get much benefit from the glasses - I would have been curious to try the effect, but it would have been something rather special for me to consider parting with that much money for them! I can't say being colour blind has really affected my life (since I was a kid and used to colour the sky in purple anyway!) although I do sometimes worry when retouching images that I might get the colours way off. It would be interesting to see colour how other people do - as it is, it usually ends up coming in conversation, we have a good laugh at me trying to read the numbers on the test, and then I forget all about it again!
