Polycarbonate was first developed and used for aerospace applications. Astronaut helmet visors and space shuttle windshields are two products made of polycarbonate.The lightweight, impact-resistant material was later adapted for use in eyeglass lens manufacturing.Polycarbonate lenses are now the industry standard for safety glasses, sports goggles and children's eyeglasses. They also are a great choice for rimless eyeglasses (which have minimalistic frames that are attached to the lenses with small drill mountings.)
Polycarbonate is a thermoplastic that starts as a solid material in the form of small pellets. During lens manufacturing, the polycarbonate pellets are heated until they melt. The liquid polycarbonate is then injected into lens molds, compressed under high pressure, and cooled to form a finished lens. The entire process takes only a few minutes.
Sunglasses lenses made from polycarbonate material are extremely flexible and resistant to impact. In fact they are more than 40 times more impact resistant than standard plastic lenses. Polycarbonate is also lightweight and therefore comfortable to wear and blocks 100% of the sun’s harmful UV radiation. More than 90% of all safety glasses are made with Polycarbonate lenses.
All Torege lenses are impact-resistant, designed to meet the impact resistance standards of the American National Standards Institute (ANSI) Z80.3 and EN 1836:2005 as well as the FDA regulation 21 CFR 801.410 for impact-resistant lenses for general use.
Our Toriex™ lenses are designed for high mass and high-velocity impact protection. This mean that they will provide excellent protection for general active lifestyle conditions such as biking, running, golfing, rafting, climbing, hiking, sailing, walking. However, non-prescription lenses are not intended for industrial safety use as defined in ANSI Z87.1.
