My dad was staking out some pea plants, when he bent down to pull a weed and got the stake right in his eye.I was paying for my dinner in the works canteen and, unusually for me, used my credit card. Just as I was about to pay I had an itchy nose, and poked myself in the the eye with the corner of the credit card. Hurt more than I expected but sat down to eat my dinner. Half way through my dinner someone else joined the group and said "my god, what have you done to my eye", then various comments from around the table "you need to get that looked at" followed by "seriously, you need to get that looked at - go to casually right now !" I'd managed to nick the surface of my eye - thankfully not the lens - but looked like Dracula. I only saw it after returning from casualty - it was just eye drops to help healing and prevent infection - but it looked ghastly. That is probably my silliest visit.
And to sympathise with Accy's paint incident - you don't want to f-about with eyes. Fair enough if emulsion paint washes out, but if it persists or in hurting or is a more "chemically" paint 'd get it looked at.
He had months of repeat visits to the eye specialist. We were very worried but thankfully no long term damage.
He also did the classic error of unjamming a clogged lawn mower whilst it was still plugged in. Resulting in severed tendons in his fingers. He was home alone and drove himself to hospital with his hand in a tea towel. He is in his 70s now with a claw hand.
