I'm glad there is no long-term damage.

The two most important things to a mechanic are his/her hands and eyes. Keep them safe. Saving a few seconds isn't worth loosing a body part.

I can't count how many times my glasses have saved my eyes from dirt, oil, tools, nuts, bolts, etc...

I once spent three hours infront of a mirror plucking a feather out of my eye that came from my pillow.
