What type of sunglasses are not authorized for wear with the Army uniform?

Sunglasses that are trendy or have conspicuous designs are not authorized for wear with the Army uniform because military regulations emphasize maintaining a uniform and professional appearance. The goal is to ensure that soldiers present a cohesive and disciplined look that reflects well on the Army as a whole. Sunglasses that feature flashy designs or overly stylish elements detract from this professionalism and could make it challenging to maintain a standardized appearance among service members.

In contrast, polarized lenses can be beneficial for reducing glare, basic black sunglasses can be deemed more subdued and appropriate, and prescription sunglasses are important for soldiers who require vision correction while still adhering to the military's uniform standards. The emphasis is on practicality, functionality, and a uniform look, which is why trendy or conspicuous designs are not suitable for wear with the Army uniform.
