Randolph Engineering began as the American dream - two immigrants that started a company making machines to build the parts for other metal eyewear companies. As the others started moving overseas, Randolph started their own sunglass brand and remains the last of the metal eyewear companies made in the United States. Having had a contract supplying the standard-issue glasses to the military since 1982, Randolph is known for their exceptional quality and attention to detail.
