    Hello yeeha,
    Just did the test 2 days ago...and I have red/green colour difficiency....as its called.
    I have real trouble with the Ishihara discs, I just did the test and same results as you....You'll be fine in the test.
    In the Thai test they only use red, green and yellow....the guy points to the different colours about 3 of each....easy.
    Then you do a test with a cable and 2 markers, getting them parrallel to each other, might be a bit tricky if only one eye!
    Next test you put your face right up against a machine with your nose as the distance gauge. You look straight at a yellow dot and on your left and right periphiral (Sp?) vision they change the colour diots thru red, yellow green. I had trouble here and couldn't work it out had a few goes and was made to wait. Last go I sat in a chair instead of squatting...akward height. This made it really easy to see. If you have trouble get as low to the machine as you can..
    Hope this helps some..

    Also it all depends on who's doing the paper work etc at the DL place. With the correct paper work they might just want to get rid of this annoying farang & get you out the place asap. It happened to me with my bike licence & car licence. If your doing it in some back water place then you could be lucky but in Pattaya for example they're more use to dealing with us so take your pick.

    cheers guys
    thanks for the replies
    im feeling better prepared now

    i used to work as a commercial diver and have bad memories of the dive doctor and how he used to roar with laughter when we did the Ishihara disc tests every year.
    it never stopped me getting my certificates year after year and my boats mans certificate.

    cool

    How would red/green deficiency affect your driving abilities?
    Everybody knows red is the upper, green is the lower light.
    If in doubt, stop, and the guy behind you will honk if it is green . . .

    The ishara test is discredited in the medical profession ,but industry still uses it as a standard I am not colour blind but cannot pass the test which has cost me many jobs, but eye specialists tell me i have enhanced colour vision .

    My eye specialists in UK have told me the Ishihara test is rigid but a useful guide to trained specilists but when used by many industrial medical auxilaries and government dept who do not understand its limitations it causes many false faliures. I have been told at many job interviews that i am totally colour blind and only able to see in black and white as far as the ishihara test is concerned , but 5 eye specialists have told me that I am able to see all colours perfectly and that the test is flawed this has cost me some well paid jobs in the UK. In fact in the electronic indusrty I am able to see all small colour codes on components and when i was in the military i could easily pick out camouflaged targets .

    I have had the Farnsworth Munsell test and it show my sight colour vision to be great, the problem is that the Ishihara test is the one that governments and industry insist on and is often overseen by untrained company medics or H&Rmanagers .
