For those who have never scratched their cornea I should add that it is the of the most painful injuries.

I was literally rolled in a ball wanting to die when it happened to me. I went to hospital to get it looked at (ha, eye pun!) and when the doc put some eye drops in to numb it I practically gibbered my gratitude.

Turns out you have to let it heal by itself and the eye drops works be wearing of in an hour or so. 3 days off work so I could lie on a sofa with my eyes closed. Fun times.
