about a year ago, i was working as a mechanic. i always wear eye protection when doing tasks that require it. so i was on a test drive one day and was going about 45 mph with the windows down due to the fact that it was summer, and turned on the a/c vents to test the air conditioning when debris came out of the vents. and some flew into my eye. it was quite irritating for some time so i went into the bathroom with a pretty bright flashlight and could see something about 1 mm from my pupil, it appeared to be metal or plastic. i tried to get it out with a powerful magnet, which did not work. i proceded to urgent care clinic, they put yellow dye in my eye and used a uv light to see if they could isolate it better. after giving me numbing drops i decided to leave, i asked if i could have the drops (which i later found out they legally couldn't) they gave me the drops and i went home to eat dinner before i headed to the ER for the next 8 hours... as my eye was now numb i decided to try and use a q-tip with a slight spinning motion to hook the exposed part of the debris. i was successfull at removing about half of the debris, good news was that now it wasn't going to scratch my eyelid anymore, bad news is i couldn't be sure there wasn't still some in there! i made an appointment the next day with my opthamologist. he said under magnafication that ther was more in the eye. he numbed my eye and said please press your head firmly in the head rest and do NOT move your eye or head at all. he proceeded to use a DENTAL PICK to try and remove the debris... (i couldn't feel it but it was awkard because my eye was moving all over the place.) that didn't work. he then went on to ask his nurse for a "bit" i asked, "as in drill bit?" he said yes. he then said i must stare directly at the drill bit and not move otherwise. it was like a scene from a movie where aliens abduct someone and insert a needle in the eye!! he successfully removed the debris, prescribed some anti-biotic drops and steroids. about 2 hours later the numbness completely wore off.... NOW THE PAIN SET IN. needless to say though this wasn't the most painfull experience it was quite disturbing.
I am always carefull when turning on vents in cars that people might not use often now!
ALWAY WEAR EYE PROTECTION!
