Add to that the fact that I am from Birmingham and, in truth, I haven't got a lot going for me. http://caughtinthemiddleman.wordpress.com/2008/01/16/man-flu/ Being both red-green and blue-violet colour-blind I can fully emphasise.

The rate is like 5-10% of the male population so its uncommon but not really rare, so you've probably met other colourblind people but not known as its not really obvious unless you find them trying to pick ripe bannanas or something! Yes it can effect people to different degrees. Some people are extremely severe and it becomes obvious very early that they are colour blind. Others are like me and moderately bad its also pretty obvious early in life particularly as its hereditary and so family members are often aware of the condition as their fathers/uncles etc had it. However some people go through most of their lives and only discover it when they've been made to a colour blindness test say for a pilots license. So basically it can be a full range, and this is just for the people like me who are missing only one color of three. Some people apparently see only essentially shades of grey but this is very rare.

I asked a couple of opticians about it recently and neither of them had any idea what I was talking about. As I've just started searching for information and this was the first place I found something that matches my own experience I thought I'd get in touch. So, thanks for posting the article Steve, and Sacha for responding. Hi Sacha -

Thanks for the hint. It sounds certainly very interesting. Almost like a Husky, which has a green and a blue eye ;-) Sacha have you taken some tests just with one eye? You can find some more <a href="http://colblindor.whitesands.ch/category/tests" rel="nofollow">tests here</a> - if you like. It would be very interesting to know the results.

I'm also colorblind and I fell myself in the same postion as you are describing here. But I think color blindness does have some impact on every day life, specially when I'm biting into a green banana :-) Sacha, very interesting your one eyed color blindness. And Steve, do you have a source where they write about one eyed color blindness? Would be great to read something about it. Very nice article which sums it up very well.
