When eyeglasses became some sort of effective possible-romance repellant, that says a lot about its appearance. The GI glasses, also known as “birth control glasses,” did not disappoint in terms of making even the most attractive, badass military personnel like the biggest dork out there. On the other hand, if you fancy thick black rims and lenses that look like magnifying glasses, then it’s definitely for you.

Recruiting Men With Poor Eyesight

The ancestors of these rather unsightly glasses could be traced back to World War II when the Army recruited tons of people with bad eyesight for the Allied campaigns in Europe and the Pacific. Lt. Col. F. C. Tyng, commanding Fort McClellan in Alabama, wrote a letter informing that 75 of his men had broken their eyeglasses and couldn’t afford to have them replaced. According to The Medical Department of the United States Army in World War II:

In less than a month, on recommendation of The Surgeon General, the Medical Department was directed to provide spectacles repairs and replacements to all military personnel needing them. In the meantime, a plan had been developed to obtain spectacles by letting contracts with optical suppliers in each of the nine corps areas. Since this would have involved nine separate contracts with widely separated contractors some of whom were unable to fill the requirements, this plan was abandoned and a strongly centralized procurement program was adopted.

Ugly For A Most Practical Reason

The result was a P3 lens shape made to be used with gas masks. P3 refers to the tilt or angle of the bottom of the frame rims towards the eye that helps in providing more precise vision correction. After the war, cellulose acetate was used in place of the nickel alloy wire. These were thicker than the normal eyeglasses to protect the wearer’s eyes at the same time, enabling them to see the world clearly. They were originally color gray but were replaced with black after all stocks were exhausted. Black remained the color and design of the GI glasses from 1968 to the 1970s until the redesign with the S9 frames.
