GI glasses are eyeglasses issued by the American military to its service members. Dysphemisms for them include the most common "birth control glasses" (BCGs) and other variants. At one time, they were officially designated as regulation prescription glasses (RPGs).[ citation needed ] This was commonly said to mean "rape prevention glasses" due to their unstylish appearance.[ citation needed ] At times in the US Navy they were called to "Standard Navy Ugly Glasses" (SNUGs). Similar glasses (without metal) can be issued to inmates in state and federal prisons.
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 eye protection ballistic eyewear.

A corrective lens is a transmissive optical device that is worn on the eye to improve visual perception. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye. Contact lenses are worn directly on the surface of the eye. Intraocular lenses are surgically implanted most commonly after cataract removal but can be used for purely refractive purposes.
Glasses, also known as eyeglasses and spectacles, are vision eyewear with clear or tinted lenses mounted in a frame that holds them in front of a person's eyes, typically utilizing a bridge over the nose and hinged arms, known as temples or temple pieces, that rest over the ears.
Sunglasses or sun glasses are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes.

They were very popular during the 1950s and 1960s, especially in the US. The glasses were first manufactured by Shuron Ltd in 1947 under the "Ronsir" brand, and quickly emulated by various other manufacturers. The design became the most common style of eyeglasses throughout the 1950s and the early 1960s before it was surpassed in popularity by solid plastic styles. Browlines enjoyed a renaissance as sunglasses in the 1980s before returning to popularity in the 2010s, with the rise of retro style and the hipster subculture.
Cat eye glasses are a shape of eyewear. The form is closely related to the browline style, differentiated by having an upsweep at the outer edges where the temples or arms join the frame front.
