vision test is corrected...I tried to do it uncorrected just for the hell of it...couldn't squeak out 1 friggin letter on the tiny line at the bottom...after about 12 guesses we both laughed and I put on some glasses so I could read it.
If you wear contacts, take all your contact solution and whatever you need to take them out/put them back in because they will have to be removed for the glaucoma/puffer test.
And...
No, the interview isn't that bad at all as long as you study the gouges and come prepared...nothing out of the ordinary was asked....just things that any decent CFII *should* know.

I have to admit, I didn't know any of the RVR rules/requirements until I started studying for my AE interview though. ....but trust me, you NEED to know it... You WILL apply those rules EVERY day in the sim and out on the line when the weather goes to hell.
