Polycarbonate lenses are high index lenses that are known primarily for their exceptional impact resistance and anti-scratch coating. If you or your children are always bumping, scratching or dropping your eyeglasses, this is the material for you. Up to 10 times more impact resistant than standard plastic eyeglass lenses, polycarbonate is a first-rate option for people with an active lifestyle. Developed in the 1970s, polycarbonate has been protecting eyes for quite a while.
Superb Eye Safety
If you regularly engage in sports or physical activity, these tough, durable lenses provide an extra degree of safety for your eyes. In fact, most protective eye gear and sports goggles are made from polycarbonate lenses, even when no vision prescription is needed. In addition, polycarbonate boasts built-in protection from the sun’s UV rays, making this an ideal lens material for time spent outdoors.
The refractive index of polycarbonate lenses is 1.59, which results in a lens that’s 20% to 25% thinner than common plastic lenses. Weighing in at 30% lighter than regular lenses, polycarbonate takes a load off the bridge of your nose!
