When I was sixteen, I was playing around on my dads bench grinder sharpening something. Of course I didn't have any eye protection on. And nothing eventful took place, until about 9.00pm that night. I started developing a minor irritation in my left eye, which quickly developed into the worst pain ever by midnight. Trying to locate the source of this pain seemed impossible, and somehow I made it through the night. Early the next day, and a trip to the ophthalmologist revealed an incredibly tiny sliver of metal lodged right into center of my cornea. The doc explained that the pain caused later was a result of the rusting metal. And that incident made me realise just how lucky I was.
It may be a lottery, but one I wouldn't want to win. Pair of safety glasses are cheap.
