HOYA PHOENIX lenses made from PPG TRIVEX lens material show less damage in impact testing

PPG (NYSE: PPG) today announced the results of tests carried out in collaboration with HOYA Vision Care to compare the performance of PPG TRIVEX® lens material to polycarbonate across multiple optical and durability categories. The data showed that HOYA PHOENIX® lenses made with PPG Trivex lens material exhibited less damage during impact testing, lighter weight, higher optical clarity and better chemical resistance than comparable polycarbonate lenses.

Recent data shows that HOYA PHOENIX® lenses made with PPG TRIVEX® lens material exhibited less damage during impact testing, are lighter weight, provide higher optical clarity and better chemical resistance than polycarbonate lenses.

The research was designed to test the impact performance of PPG Trivex lens material against polycarbonate, a popular lens material used in prescription eyeglasses. Data on other attributes, including weight, chemical resistance and key optical data such as Abbe value and birefringence was compiled from earlier research. The findings provide a scientific basis for eye care professionals to recommend HOYA Phoenix lenses made with PPG Trivex lens material as a high-performing alternative to polycarbonate.

“Today’s patients have high expectations for their eyewear,” said Raymond Hudack, PPG global business director, optical monomers and coatings, Specialty Products. “Lenses must be able to offer lightweight comfort, exceptional optical clarity and protection from everyday wear and tear. PPG Trivex lens material sets the bar for high-performance lenses, giving eyecare professionals an opportunity to differentiate their practice with a proven solution.”

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.”
