As a long-time glasses wearer I don’t imagine they’d be 100% identical, that would be near useless for most wearers who weren’t like, -1 myopic if that were the only glasses provided.
Anyone with astigmatism or a higher prescription (probably starting at -3 and stronger) would be probably better off not wearing glasses at all than wearing mis-prescribed glasses, and at that point their eyesight would be too poor for standard activity.
Frames also need to increase in thickness as the prescription increases, because the lenses get proportionality thicker too. A thin frame will either be too narrow/weak to hold the lenses, and the overhanging glass is a physical hazard
Yeh definitely worth asking and tbf I don’t have any special insight into how the military would do it other than the fact that I’ve walked around with glass in front of my eyes for most of my life.
I’m guessing maybe they’d have standardised frames and lenses that go up in gradations of 0.5 or 1, and can easily be swapped out. They probably wouldn’t allow for astigmatism because that’s different for each person so the correction may be off for some wearers, but so long as the degree prescription is okay they probably make do.

Yeah, it would be stupid and counterproductive, but we’re talking about the US military so I figured I’d ask.
