Seeing that some of the color vision forums date back to 2009 I am curious as to what the current regs are. I currently have a night restriction after 8 years of passing the ishihara plates. I have tried the farnsworth and did not have luck with that. However I find it strange Bc I have never had any trouble identifing colors on the aircraft/airfield. I am looking to get my commercial single engine add on and CFI with a second class medical. Am I able to have a second class with a night restriction?
