What Are Polycarbonate Glasses?
Polycarbonate was developed in the 1970s for aerospace applications and is currently used for the helmet visors of astronauts and for space shuttle windscreens.
Polycarbonate lenses were introduced in the early 1980s in response to a demand for lightweight, impact-resistance lenses. Since then, polycarbonate glasses have become standard for safety glasses, sports goggles and children’s eyewear.
Polycarbonate glasses are thinner and lighter than regular plastic lenses. They also provide 100 percent UV protection and are up to 10 times more impact-resistance than plastic or glasses lenses.
