GI glasses

GI glasses are eyeglasses issued by the American military to its service members. Dysphemisms for them include the most common "birth control glasses" (also called "BCGs") and other variants. At one time, they were officially designated as regulation prescription glasses, or RPGs. This was commonly said to mean "rut prevention glasses" due to their unstylish appearance.

History

The original version was designed for use with gas masks during World War II. It was wire-rimmed with cable temples and a "P3" lens shape. The design was a modification of the style used by the British military.[1]

After World War II, the material was switched from nickel alloy wire to cellulose acetate. Initially gray cellulose acetate was used, but this was discontinued in 1968, with remaining stocks issued until exhausted. The replacement frames used black cellulose acetate.

In the late 1970s, the lens shape was re-designed to the "S9". Black "S9" frames were released for a brief period,[2] before brown cellulose acetate replaced the black. The brown cellulose acetate frames were discontinued in 2012, and a new smaller unisex lens shape, the "5A", was introduced, with a black frame. The modern "5A" shape was designed by Rochester Optical, who is the exclusive manufacturer of the R-5A frame.[3]

GI glasses are issued at government expense to new recruits at recruit training or Officer Candidate Schools in the United States military. When entering recruit training, service members may wear civilian glasses until government-issued ones are assigned, including but not limited to the BCG. Contact lenses are never permissible for these exercises. After recruit training, service members are permitted to wear Frame of Choice glasses which are conservative in design and color or contact lenses. The military offers annual replacements for those who qualify, and personnel may request the government issued glasses in addition to several varieties of more attractive eyewear, in clear and tinted lenses, as well as prescription gas mask inserts and inserts for government-funded ballistic eyewear.[4]

Manufacturers
gollark: I'd also expect places which seem to actually care to have sensible somewhat-long-term-viable (i.e. non-lockdown) plans for dealing with stuff.
gollark: This is cool, I have apparently been randomly picked for a COVID-19 testing study.
gollark: I don't really like old games, and I generally had a lot of free time *anyway*.
gollark: Mostly fine. It's better than school, at least. It would be nice if I could actually try some new activities or something though, since that stuff seems to mostly be shut down.
gollark: I am hoping that whoever is behind that won't decide to try something like this again, but I bet *someone* will think "ah yes, this is a great idea, we'll just lie because it's mildly more convenient, that can't go wrong in the long term".
