I have been wearing glasses all my life and had them when I was drafted in 1951.
In Basic camp, they orderd me two pair of glasses to follow me around until they caught up with me in Korea, fall of '51.
There was a pair of steel rim glasses and a pair of plastic rim glasses in the box that caught up with me.
Because I still was wearing my "civilian" glasses, from home, I never used those Army glasses and I was lucky enough to be able to wear my own glasses all the time I was in Korea, without incident.
Even the times I had to jump into a hole. Talk about "luck"!
I don't remember what I did with the Army glasses after I came home or even if I brought them with me! ha ha
Without my glasses, I can't even see the big E.
The Army didn't care but I couldn't get into the Airforce in 1948 when I tried!
