Unless the airline is demanding perfect, uncorrected vision or your eyes are very different (blind in one/ perfect in the other!), can't see you having a problem.
Being able to read the bottom line aided or unaided is well in excess of the required standard (which if I remember rightly is the third line up from the bottom). I have a class 1 and can't even see the board without my specs on! With specs, I see the bottom line clearly in one eye and slightly blurred with the other... Your issue doesn't even need specs by the sound of it (your other eye is compensating easily if you weren't aware of any effects) so you'll be fine.
