After reading this I checked the lens of my "better" pair glasses...the ones I wear most when shooting.
After a good gleaning, and close inspection, I'll be dad burn if there ain't something going on with that right lens...nothing real serious, at least yet, but there is a lot of little tiny pitting going on that is not present on the left lens.....
Although I have never actually noticed any of this before, and certainly never anything while I was shooting, it was comforting to know I was in fact wearing glasses when these things did happen.
It also made me think back and wonder what the early folks did, and how many may have suffered eye injury.
