Product Features
Polycarbonate(PC) lenses are lighter and thinner than regular plastic eyeglass lenses. But they are up to 10 times more impact-resistant than traditional plastic lenses and they can offer 100 percent UV protection. All these make polycarbonate lenses an excellent choice for safety glasses, children's glasses, sports eyewear.
 | 1. Impact Resistant
Polycarbonate material was originally made for uses on canopies covering fighter planes and then made its way into space on astronaut visors and space shuttle windshields. Today it is readily available to the public. It impact resistance makes the material extremely suitable for sports, industrial safety goggles, and children's eyewear.

2. Scratching Resistant
The reason for polycarbonate lenses' impact resistance is because of its "softness". Softer materials will flex instead of fragment when met with great force. However, the property allows lenses to be scratched easily. Therefore, every single one of our polycarbonate lenses is multi-coated with hard coating that forms a protective layer around the lenses allowing the lenses to be free from scratches while retaining its impact resistant qualities. |  |
