Lens Materials

High index lenses 1.6, SuperHigh1.67 and UltraHigh1.74 produce the thinnest and lightest plastic lenses on the market today, up to 50% thinner than standard lens materials.

Airwear and Trivex offer ultra-light, nearly indestructable lens options often used in drill-mount and semi-rimless frames.

Listed below are materials types and how they will benefit your wishes for the lightest lenses posssible
