Failing colour perception tests

[flying ninja]

Ok I've not even been in the AFCO yet but i was just wondering what will happen when i fail my colour perception test because i am colour blind.
I'm sure i once read that some one had to go to Brighton when they failed their colour perception test, which i would find abit arsey for me because i'd have to travel there from Doncaster.
So what's the usual procedure when this happens, just so i can some up the positive and negatives before going to the AFCO which also means traveling because it's in Sheffield and Doncaster only has an army careers office.

Your best bet is to pick up the phone and ring your AFCO. As we all know, nearly every AFCO has different facts or opionions on everything from what time you should be running your 3 miler in, to what time you need on your PJFT.

Ring your AFCO and ask them, or ring around a couple and you may find an answer that's more favourable to you. I know that last part sounds daft but believe me, you'd be surprised.

Yes that was me pal.

First up you'll have to do a Ishihara test, like this

That will tell them a fair bit, such as what type of colour blindness you have. Info on that here

Then you should have to do a matching wires test (which I believe is specific to the Marines, meaning you may not find any info/pictures on the net). It's basically 20 different coloured electrical wires (some are stripey/hooped, most are plain) which have all been cut in half and you have to match up within 5 minutes (although as I learned the time varies depending on where you do it).

If you get any of these wrong you will then have to do another test, the Farnsworth Lantern test - limited info here

This is basically that little box with 2 lights in it. You sit 10ft away and it cycles through a sequence of 9-15 variations of colours - white, green and red. Everytime it changes you have to say which lamp is which - IE. red top, green bottom - green top white bottom, etc. etc.

Then you sit in a dark room for 20 minutes so your eyes can adjust and do it again in the dark.

The Navy judge colour perception from 1-5 (1 best - 5 worst). Get 4 or above and you're ok, 5 is a fail. Application terminated.

I only had to go to Brighton because I got one of the wires wrong and because the medical centre in Portsmouth didn't have the right equipment to do the Farnsowrth test and Brighton was the closest.

Ok cheers for that.

But one question, you this bit

If you get any of these wrong you will then have to do another test, the Farnsworth Lantern test

By that do you mean if i get any of the wires wrong or if i get any of the wires and ishihara tests?
Because i know i'll be done over on the ishihara tests because i can't do them to save my life, but i think i might be able to do the wires test because i've seen that before on a tv programme about training electritians.

No worries mate, at the end of the day don't fret about it because there is nothing you can do about it.
