Hi Will,
I'd certainly like to keep in touch. I'd be more than happy to keep you updated with regards to my colour vision testing over here in the UK.
Yeah the only tests now that the CAA accept under MED.B.075 are:
Ishihara (First 15/24 have to pass)
CAD testing
Anomaloscopy (Nagel or equivelant)
Lantern testing (Beyne, Holmes-Wright or Spectrolux)
Unfortunately doing the D-15 at the city Uni may only help in an appeal.
