Back in ‘98 I worked for a company installing trailer hitches. Sometimes you have to lay at odd angles to get into the space to install the hitch. One day I was at an angle that a small shard of metal went under my safety glasses and into my eye. I did not think much of it until later that night when my eyelid started to catch on the metal. I went to the ER and they extracted it. But it was so much rust it dissolved in my eye. I had to have eye surgery the next day to remove the rust. I am now going blind in the eye. The doctors cannot say with certainty it is because of the injury, but it is the likely culprit. My other eye still has really good vision.
During and immediately after the accident the company took really good care of me. All my medical bills were paid, I was given extra leave. It was not until 7 years after I left the company I found out how bad my vision was (because it was a slow degrade I did not notice).
