CASA color defficiency
Recently as a student pilot, i have received a restriction on my class 1 saying Not valid for night flying. The color test done initially is the Ishihara which i failed. but then i proceeded to do the D15 test which i passed but then CASA says it is not a valid test however NZ sees it as a valid test that meets ICAOs requirements as well. I then did the Lantern test which is quite difficult where even some people with normal vision struggle to do. I am on my last thread with testing with only the CAD or Operational color assessment to do. I appreciate all the work done towards CASA on allowing more tests but I do not think that the tests that CASA has is fit enough to diagnose someone properly. I have wanted to go to an Ophthalmologist to do extensive testing and to send a report to CASA for review but I got denied this. I honestly have no idea what to do now.,
