I once knew a man who was a tail gunner on a Flying Fortress during WWII. Like many others, his plane was shot down over Germany. He lived but lost an eye. German doctors patched him up and gave him a glass eye. I was surprised at the time that he could drive an auto with no evident problem so I would give the patch a try and see how it goes.
It was particularly interesting to me that he was held at a POW camp named Stalag 17. There was a book and a Broadway play and movie of that name which at that time were big hits. My friend was something of an artist and to pass time made many sketches of camp life that he kept in a scrap book. Up until I met him anything about WWII was somewhat mythical and unreal.
