I told the (true) story a while back, of my pal who asked for the anti-dilater type drops to counter the effect. He was on a Dublin bus and his eyes closed down till everything was so dark he had to ask for help. They said the blind home was two stops down...and of course he replied. "Oh no...I'm an airline pilot, I need the airport service road."
He said that he tried to keep a straight face.
The thing is that the drops cause blurring as well. The poor vision is not just the iris ‘setting'. So the anti drops were....er, dropped.
