BB reminded me that you're an eye Dr. How about a freebie?
Last Friday a piece of rust hit my eye, even though I was
wearing safety glasses. I believe it bounced out right away,
but the next day it was all red and very, very sore.
Couldn't see anything in there, but stilI washed it out
several times. In the morning my eyelid was stuck closed,
till I washed it. It got better by Monday, so I didn't see
our Doc. it's fine now.
My Q is, could that have gotten like that even if the piece
of rust didn't stay in. Bruised eye?
