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 indestructible lens options often used in drill-mount and semi-rimless frames.
