I have a SODA/waiver for amblyopic left eye. I had to take a test flight with the feds when I went for my first medical in'94. It was not a big deal. My vision in my left eye is only corrected to 20/30. I have also worked for a major airline and NetJets before and it was not an issue with either. The SODA does not have an expiration date. If you have any questions feel free to PM me.
