Randolph optics co., ltd was founded in 1972, and its headquarters is located in Massachusetts, USA. At the beginning of its establishment, the company was mainly engaged in the research and development of optical instruments and optical finishing machinery. With pioneering spirit and excellent product quality, Randolph not only achieved the expected success in the field of optical glass, but also established a huge customer base and a smooth sales network. Randolph's aim is to make excellent optical glass products with advanced optical principles and engineering theories. In the United States, Randolph and A&O are the most competitive rivals in business. Their main focus of competition is the order of the US Department of Defense, because the US Department of Defense purchases a large number of sunglasses and distributes them to air force pilots every year.
The products of Randolph and A&O are of high quality, but Randolph is constantly innovating while constantly improving the quality. Randolph's straight-arm sunglasses designed by them have always been the favorite of pilots of the US Air Force, so that Randolph directly participated in the formulation of the US military sunglasses standard, which has been adopted by the air forces of Australia, Belgium, Israel, Jordan and other countries. And those civil aviation enthusiasts regard Randolph sunglasses as an essential equipment. So in order to meet different market demands, almost every Randolph sunglasses has two products, the so-called civilian version and the military version.
Randolph sunglasses are widely valued, and their products have distinct characteristics and advantages: the lenses are neutral gray-green with moderate wavelength, which will not change the original color of the object, and the traffic signals, whether red or green, will not be affected; The mirror hinge between the mirror frame and the mirror legs is fine and firm in design, which can be moved flexibly and will not be easily loosened and deformed; Most products use straight arm temples, which are flexible and durable, increase the comfort of the wearer and do not affect the user's wearing helmets and headphones.
