Final answer:
The U.S. Army has regulations in place for the use of eyeglasses to ensure compatibility with military equipment and effectiveness in duty performance. Army policy aims to provide functionality and safety for servicemembers who require corrective eyewear.
Step-by-step explanation:
The question is about the Army policy regarding the wearing of eyeglasses. The U.S. Army has specific regulations for the wearing of eyeglasses that are not sunglasses. These regulations ensure that the eyewear does not interfere with soldier duties, especially when using specialized equipment like night vision goggles. It's essential for eyeglasses to be compatible with military equipment to maintain the effectiveness and safety of the personnel. The information provided from Wikimedia Commons, regarding night vision goggles, suggests that they must be worn comfortably and efficiently with any corrective eyewear, which would be part of these Army regulations.
Regarding past history, the mention of Pol Pot's regime in Cambodia and the targeting of individuals wearing eyeglasses as a mark of intellectualism showcases a stark contrast to the supportive, functionality-focused viewpoint of military eyewear in the U.S. Army. It's an important cultural and historic consideration, but not directly related to the current Army policy on eyeglasses.
