Stringent Testing Shows PPG TRIVEX® Lens Material Outperforms Polycarbonate

Clear solution balances optical clarity, comfort and durability

What sets PPG Trivex lens material apart?

PPG Trivex lens material combines optical clarity, impact resistance and lightweight comfort to meet diverse customer needs. 

• Impact Resistance^*
  Lenses made with PPG Trivex lens material demonstrate strong durability in high-impact conditions. Unlike polycarbonate lenses, which showed dimpling during Gardner Impact Tests, HOYA PHOENIX® lenses with PPG Trivex material maintained their integrity, making them an ideal choice to prevent lens damage in everyday wear, and especially suitable for sports eyewear and safety glasses.
• Exceptional Optical Clarity 
  PPG Trivex lens material demonstrates exceptional optical clarity due to its high Abbe value, which reduces the “rainbow blur” that can appear around the edges of lenses, ensuring consistent sharpness across the entire lens. The cast-molding production process reduces birefringence, helping prevent blurriness or distortion. Together, the result is uniform clarity across the lens surface.
• Lightweight and Comfortable
  With its exceptionally low specific gravity, PPG Trivex lens material offers a lightweight lens option for all-day wear, reducing strain without compromising performance.
• Chemical Resistance
  Through chemical submersion testing, PPG Trivex lens material was shown to resist damage – including scratches, discoloration and crazing – from common chemicals, helping to support long-term functionality and clarity.
