    I am colorblind too. I've known pretty much my whole life.

    On a side note: For those of us who don't know what colorblindness looks like, go to www.vischeck.com and click on the examples tab. There you will find different levels of colorblindness and what it looks like to the person who has it.

    You can find a colorblind test anywhere on the web. Just type "colorblind test" in the search field of google and check out for yourself.

    now this is a fine example of teamwork. one throws out a topic and the other provides all research info. ;)

    Hmmm... I wonder if they've got it round the wrong way. I wonder if the non-colour blind people are colour blind. Perhaps we're the odd ones out...

    Apparently I'm "normal".

    True indeed. That and I wanted to squash the question we've been asked for all of our lives..."You're colorblind?...Does that mean you only see in black and white?" or "So, since you're colorblind, why do you own a color TV?" :lmao:




    My smart alec answers for thost two are: "More like shades of grey." and "I've been looking for a good 32" black and white television...do you know where I can get one?"

    Night blindness is usually called Nyctanopia.
    It can just be genetic but it can also be due to Vitamin A defficiency.
    If you have not had it checked out I would see a Doctor or an Opthalmologist and get it looked at immediately. Sometimes the problem can be cured, but it can also be an indication of serious illness.

    Colour 'blindness' is more correctly called 'colour deficiency'.
    Confusion tests (like the ones on the web pages) are only crude screening proceedures at best. The specific colours used are critical and so the tests will be even less accurate when seen on a monitor.
    There are three basic kinds of colour deficiencies:
    Red/Green
    Blue/Yellow
    Total
    Red/Green is the commonest - and is far more common in males than females.
    There are degrees of colour deficiency too, from just seeing colours slightly differently to not seeing them at all.
    There are far more accurate tests available - the Anomaloscope is one - which can accurately measure colour vision. But you have to pay for them.
    When I was working professionaly I used to have my eyes checked over once a year. I found that my left eye sees things about 1 unit more magenta than my right - which is b*gger all but I can still see it if I switch between them.
    A close friend and fellow photographer suddenly discovered that he was red/green deficient after more than 25 years. He thought everyone saw trees in various shades of grey!
    He was reconciled to it when he found that one of the ways he could cope with it and get help differentiating between the colours was to wear a red monocle.
    It was still frightening at night when he drove, though. He used to have to guess what colour the traffic lights were :lol:
