Note to self. Buy multiple sets of eye protection!
Of all things to hurt your eye with I cut mine on a friggin leaf. About 20 years ago I was walking along a foot path at work and one my friends pointed at something over my shoulder. I looked left and walked right into a small tree branch. A small green leaf cut across the center of my pupil. The edge of the leaf had a very small serrated edge.
I work at a hospital and made a bee line for the emergency room and my boss saw me waiting in the waiting area. Told her what happened. Five minutes later she grabbed me and walked me down to one of the eye specialists and he gave it a look and gave some antibiotics for my eye and all was well in about a week, but it scared the bejesus out of me.
