I've always managed to get conjunctivitis rather easily. If I'm around smokers, I get it, stay awake more than 24 hrs, put in contacts... For me to have eye surgery, I'll need to be unconscious, or I'll be getting violent to get away. The puff of air during an eye exam makes me want to inflict pain on them.
I know what you mean about that puff of air. They commonly had to do mine several times because my "blink" reflex was much faster than their instruments! Very recently, they have come up with a new instrument to measure it that does not require the 'puff.'
