A couple years ago, I blogged about Morris Fisher, a great Jewish marksman. I picked up his books, one of which is called "Mastering the Rifle" from 1940. It is full of timeless advice. However, when I first read the book, one particular nugget struck me as a strange:
Numerous shooters use eye-washes to clear their eyes before they fire in matches, or after the strain of shooting all day. Cold tea, or one teaspoon of boric-acid to glass of warm water, or a drop of 5-10 per cent argyrol, or any other solution prescribed by a doctor, may be used.
Boric acid? I know any acid can be diluted or otherwise made to be stronger or weaker, but it just seemed strange to me that competitive shooters back then would put acid in their eyes. However, lately I've been using an over the counter product called Systane lubricating eye drops which many shooters swear by.
