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 polycarb onate 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.
Lightweight Lenses
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!
Trivex Lenses
Developed in 2001, Trivex lenses are constructed from a newer plastic that shares many properties with polycarbonate. While also thin, scratch-resistant, highly impact-resistant and lightweight, Trivex lenses may be slightly thicker than polycarbonate lenses. For some vision prescriptions, they may provide a better visual clarity and more scratch resistance than polycarbonate lenses.
