Polycarbonate and PPG Trivex lens materials are both classified as high-impact materials under key ANSI Z87.1 and FDA industry standards. However, standard Gardner impact tests showed that polycarbonate received irreversible dimpling damage under high impact forces. The HOYA Phoenix lenses made with PPG Trivex lens material showed minimal surface blemishes at the same impact, demonstrating improved performance for demanding environments such as sports and industrial eyewear.
PPG Trivex lens material demonstrates exceptional optical clarity due to its high Abbe value, a measure of the optical quality of a lens and how well it controls color distortion. This reduces the “rainbow blur” that can appear around the edges of lenses, ensuring consistent sharpness across the entire lens. The cast-molding production process further enhances clarity by reducing birefringence, a phenomenon where stress inside the lens bends light in different directions, causing blurriness or distortion. Together, these properties ensure uniform clarity across the lens surface.
In chemical resistance testing, PPG Trivex lens material remained stable under prolonged exposure to lab solvents, while polycarbonate lenses showed visible surface damage and whitening. These advantages translate to crisp, clear optics, lightweight comfort and enhanced durability for long-lasting performance and improved patient satisfaction.
“For more than two decades, PPG and HOYA Vision Care have worked together to bring best-in-class optical materials to market,” said Samy Lauriette, HOYA vice president, strategic marketing. “The latest testing underscores our shared commitment to innovation and evidence-based design. As optical materials advance, practitioners have more choices to select materials that optimize patient outcomes and improve lens durability. For eye care professionals, this means access to lenses that not only meet the highest standards of durability and clarity but also support better patient outcomes and offer a compelling way to differentiate their practice.”
