Polycarbonate Lenses are thinner and more light-weight than the standard plastic CR-39 lens material. The are also significantly more durable - they are virtually unbreakable! This makes them the obvious choice for children's glasses, saftey glasses, athletes and sports enthusiasts. In addition, polycarbonate eyeglasses are a fantastic choice for stronger / thicker prescriptions, as they correct the wearer's vision, without adding additional thickness. Finally, all polycarbonate lenses have a natural Ultra Vilot light filter (UV filter). This means that your eyes are protected from the sun's harmful UV rays, and you DON'T have to spend any extra money to benefit from this feature!
KEY BENEFITS: Shatterproof, no distortion, UV protection, and thin.
