Poly Lenses - UV400 Protection and Scratch Resistant Coating
Polycarbonate Lenses are the most durable of all lenses and the safest, lightest and thinnest available. These lenses have the highest impact resistance and least likely to fracture of all lenses therefore, making them great for kids, playing sports and safety glasses. Polycarbonate is an excellent choice for rimless eyeglasses.
Trivex Lenses are ultra-lightweight and much more impact-resistant than regular plastic or glass lenses. It offers similar UV blocking properties and shatter resistance as polycarbonate lenses and can be easily tinted.

The High Index 1.67 Lenses are thinner and lighter weight than regular plastic lenses but not unbreakable and not as shatter resistant as polycarbonate. Recommended for higher prescriptions for its optical quality and also suitable for rimless eyeglasses. The bottom line is that thin eyeglass lenses are more comfortable and attractive than thick ones.
