The plates do get progressively harder to see, though my wife (who is not color blind) can easily see every plate correctly. Being color blind, i know that some are harder than others for me to see, but cannot really tell you how people with normal color vision see them:).

What you hinted at is correct, these plates are as accurate as possible, but there is every risk that they aren’t exactly the same as a physical copy of the test plates. The images are very close to the same, but everything from the lighting in your room to the quality of your monitor, and its settings will adjust this. Try doing the test from someone elses computer and see how you go – you’d be amazed how different computer monitors show colors differently!

My glasses are not scratched too badly, but if yours are as bad as you say, then i am sure they would manipulate the colors to some extent – much like cataracts? Cataracts dont directly modify your color vision, but the clouding does filter any light entering the eye.

Hope this helps,

I can do the colour arrangement test and it reports I’m not colour blind because I complete it correctly. A couple of the plates above that I couldn’t see were 73 и 5. Must point out that some of these plates I have to really look at to get the numbers. I have done the Farnsworth 100 Hue Test and manage to do very well on it. I know my current perscription for glasses has been changed slightly and these glasses are heavily scratched. I find my glasses do affect my colour vision, making colours appear slightly darker then normal. Without the glasses I have very good colour acuity but at a restricted distance. Can I just ask how accurate are these tests? Are your plates a true representation or do you think the reproduction of your plates makes it harder to see the numbers.

Thanks again, Bertie

I redid your post without full capitals for you:)

The Air Force is probably the strictest career path in the world when it comes to color blindness. Whether or not you are accepted depends on how well you do with your visual tests, and which position you are seek. Which plates did you get wrong? A couple of the plates are supposed to appear blank if you have normal vision:)

You could also try my color arrangement test, it was designed by american military personel originally, though i doubt it is used in the UK.

Glad you found the ishihara test useful:) I trialled it on a friend of mine, he’s 40 and just found out he’s mildly color blind too. To some of us it barely makes a difference i guess!
