Industry-leading clarity and quality
The PC material used for eyeglass lens was developed in the 1970s by the aerospace industry for use in helmet visors worn by astronauts. Today, because of its lightweight and protective features, PC is used for a wide variety of products including space shuttle windshields, luggage, "bulletproof glass," helmet visors of astronauts and police, swimming goggles and diving masks, Eyeglass lenses made of polycarbonate were introduced in the early 1980s in response to a demand for lightweight, impact-resistant lenses.
Polycarbonate is a large part of Syght innovation. Our polycarbonate lenses are manufactured with proprietary, fourth-generation water-white polycarbonate resins, are up to 50% lighter and thinner and 10 times more impact-resistant than glass or regular plastic lenses. Syght polycarbonate lenses have a specific gravity of 1.21. Plus, they have an index of refraction of 1.59 and can be made as thin as a 1.0 mm center.
