Colour vision exam
In the Holmes-Wright test (for Class 1) are they testing for red-green safety, or green-white as well? I know I am red-green safe, but a bit iffy on the green-white (as I discovered whilst applying for an RAF scholorship).
Has anybody out there obtained a class 1 while having some degree of colour blindness?
Thanks for any response,
Jock

I got my class 1 with a mild degree of colour blindness.. obviously not enough to make me non-colour safe, but i must admit i still have some form of colour perception problems.
When going for my class 1 i failed the first ishihara tests, but was able to pass other tests such as the desaturation ones. So the DME suggested that i mission along to an eye-specialist and get me some lantern tests done. I managed to pass one of the Holmes-Wright tests (much to my delight), and now have my full Class 1. They DO test for both red-green and white-green in the holmes wright.. so yah. I also had your same kind of colour perception problem with greens and whites. The tip i guess to the holmes wright test is in what the doctor told me, that the white light they use is actually an incadecent white (spelling.. i know i suck), which means that it's more the colour of street lighting, or a kind of yellow light. That made it easy to distinguish between green and white, because the white was more yellow to me, and the green was really pale, almost white..
sounds kinda strange, but i passed with none of them wrong, and i now got my class 1!
- hope this helps heaps dude -
