Interesting, I can see a problem though, if they were to give you a class one based on a SODA test as the US and Australia do, when it comes to the 5 yearly extended opthalmic exam required by JAR would you lose the medical if you failed the Ishihara and Holmes-Wright test?. When it came to the 5 year period, they would be on JAR regs and may not allow the SODA test anymore.
