My mate, 20+ k hours 40 years etc. Had drops to dilate his pupils. New fad, but there we are. He was told that he could have drops to close pupils, which he agreed to. Off to the loo (bathroom) afterwards. 5 mins later he was calling for someone to help him to the front door...everything was dark. Getting onto the bus he was helped by some kind soul and the conversation turned to his blind home. "Oh no! I'm and airline pilot.....I don't live in a home!"
He just told me this story, promising that it was true.
I have had dilater in twice in the last couple of years. Do NOT drive for quite a few hours after. 4 to 8 depending on you and the dilator.
