In the last 3 years Ive managed to get metaal in my eye 4 times. Yes I wear eye protection. From what I have been told my my eye doctor, the metal is never really deep but I always wait one day too long to go and see him so I usually have a rust spot that he has to clean up. Never had to have the metal drilled out. He always gets it out with a pick. Apparently I sweat like a whore in church and tend to wipe the metal into my own eyes. Go figure. As for the eye drops, they are an antibiotic. Helps the eye heal faster and lessens the chance of infection.
