The AN6531 designation refers to a standardized model used during World War II and shortly thereafter, featuring characteristic green-tinted lenses designed to reduce glare and enhance contrast in various lighting conditions, essential for aviation.
The frames, as seen, bear the BAUSCH & LOMB engraving under the brow support, as shown in the images offered, verifying their authenticity and manufacturer. The original metal case, marked with a B&L lettering within a triangular emblem along with MADE IN U.S.A., further confirms the origin. This triangular logo was a distinctive marking used by Bausch & Lomb during this period, particularly on their military-issued eyewear. These sunglasses not only served as functional protective eyewear for aviators but have since become a collectible item due to their historical significance and durable construction.
The Bausch & Lomb AN6531 Aviator sunglasses are an iconic piece of military equipment, embodying both functionality and historical significance. Originally developed in the early 1940s, these sunglasses were commissioned by the United States military for use by aviators who needed superior eye protection during critical missions. The "AN" in AN6531 stands for "Army-Navy," indicating a standard specification that was jointly adopted by the two branches of the U.S. armed forces. This standardization aimed to streamline equipment and ensure that both Army Air Corps and Navy pilots had access to reliable, high-performance eyewear.
These sunglasses became indispensable for aviators during World War II. The AN6531 model featured durable metal frames with wraparound earpieces to ensure a secure fit, even during turbulent flight conditions. The green-tinted lenses, specifically engineered by Bausch & Lomb, were a crucial advancement. Known as "neutral gray" lenses, they were designed to reduce glare without distorting colors, which helped pilots maintain visibility at high altitudes and under intense sunlight. These lenses were also capable of filtering out harmful ultraviolet and infrared rays, which were particularly intense during high-altitude flights. This technology was revolutionary at the time and contributed significantly to the safety and performance of American aviators.
Beyond their practical use, the AN6531 Aviator sunglasses became a cultural symbol of the "Greatest Generation" and the bravery of U.S. servicemen during WWII. Bausch & Lomb’s high standards for optical clarity and durability made these glasses a trusted piece of equipment, and many pilots continued to wear them off duty as well, sparking a trend that would eventually lead to the widespread popularity of aviator-style sunglasses.
After the war, Bausch & Lomb continued to produce these aviators due to their popularity both within the military and with the general public. The quality and craftsmanship associated with Bausch & Lomb made these sunglasses a sought-after item, and they were often handed down or kept as memorabilia by veterans and collectors. The design, marked by the thin metal frame, tear-drop shaped lenses, and distinctive brow bar, has since become a classic style, influencing modern eyewear and remaining a staple in fashion.
The original metal case, also marked with the B&L triangular logo and "MADE IN U.S.A.," was designed to protect these high-quality lenses from damage, especially in rugged conditions. This sturdy case further exemplifies the era's focus on durability and functionality, attributes highly valued in military-issued items. Today, both the AN6531 model sunglasses and their original cases are prized among collectors of military memorabilia and vintage eyewear, as they represent an era when utility and style were seamlessly integrated in designs meant to support the demands of aviation.
