Randolph Engineering (RE) was founded by two US immigrants, former Royal Air Force navigator Jan Waszkiewicz and machinist Stanley Zaleski. Together they wanted to build the world’s best sunglass. They built a proprietary solder machine unlike any other and patented a 200-step process, mostly by hand, to create nearly indestructible frame joints. In 1973, they opened the doors to their factory in a small town called Randolph, just outside of Boston, Massachusetts. Randolph is still family-owned and operated; handcrafting the finest eyewear with top-grade materials and a relentless attention to detail and quality; remarkably, it still takes six weeks to make a single pair of Randolph sunglasses. In an era when almost every major eyewear brand now manufacture in the far east, RE are different – still undertaking all manufacturing in the USA. In 1978, RE joined forces with the U.S. military to produce the HGU-4/P Aviator for fighter pilots. Each RE Aviator is still built to the strict guidelines of MIL-S-25948 standards. Today, Randolph continues to produce the HGU-4/P for the U.S. Army and Navy and air forces worldwide. RE have such confidence in the quality of their sunglasses they provide a Lifetime Warranty on all frames.
