Material: High-Index Plastic
Index of Refraction: 1.61 (Thinner than standard plastic and polycarbonate)
Density: Slightly heavier than polycarbonate but lighter than glass
Bifocal Design: Features a flat-top (D-segment) 28mm bifocal area for near vision.
Thinner & Lighter: Compared to standard plastic (CR-39) and polycarbonate lenses, 1.61 high-index lenses are up to 25% thinner, making them ideal for higher prescriptions.
Improved Aesthetics: Reduces lens thickness, minimizing the "bulky" look in strong prescriptions.
Scratch Resistance: Generally comes with a scratch-resistant coating for enhanced durability.
UV Protection: Provides 100% UVA and UVB protection, helping to shield eyes from harmful sun exposure.
