Excellent post. I personally love any medical related stuff. I had an incident when I was younger where I had some fiberglass in my eye and each time I rubbed it or blinked I damaged it more.

Interesting enough, I was driving and felt a similar pain years later, turned out I had a corneal ulcer caused by bacteria. Do you think that the previous traumatic injury contributed to an increased chance for infection? I'm just genuinely curious.
