After misspent years in my youth hanging around the L105 tank cannon what little hearing I have remaining I guard jealously.
Since I am blind anyway (army doctor when I applied for flight school "With your eyes the only thing you are qualified to fly is a shovel") I always wear glasses.
When at the range before I shoot I always call out to other shooters to put on their eyes and ears, especially indoors.
Have a lens from my Randolph rangers with a chip missing courtesy of a dufus trapshooter using #4 shot
Learned my lesson.
If one of those guys looses sight in an eye at the range, bye bye range
