Hot-selling 1.59 Polycarbonate PC UV420 Blue Cut Hmc 1.59 Polycarbonate Anti-Blue Ray Lenses Prescription Eyeglass Lenses
PC lenses, general resin lenses are thermosetting materials, that is, the raw material is liquid, heated to form solid lenses. PC piece is also called “space piece”, “space piece”, the chemical name is polycarbonate fat, is thermoplastic material. That is, the raw material is solid, heated after shaping into lenses, so this lens will be overheated after the finished product will be deformed, not suitable for high humidity and heat occasions.
PC lens has a strong toughness, not broken (2cm can be used for bulletproof glass), so it is also called safety lens. The specific gravity is only 2 grams per cubic centimeter, making it the lightest material currently used for lenses.
