PPG Trivex Lenses Outperform Polycarbonate in Impact Resistance, Optical Clarity, and Chemical Resistance Tests

PPG Corporation and HOYA Vision Care collaborated to test the performance of PPG Trivex lens material against polycarbonate in multiple optical and durability categories. The results showed that HOYA Phoenix lenses made with PPG Trivex lens material had better impact resistance, weight, optical clarity, and chemical resistance than comparable polycarbonate lenses. This provides 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.

PPG Corporation (NYSE:PPG) and HOYA Vision Care recently conducted a comprehensive study comparing the performance of PPG Trivex lens material against polycarbonate in multiple optical and durability categories. The results, published in collaboration with HOYA Vision Care, indicate that HOYA Phoenix lenses made with PPG Trivex material outperform polycarbonate lenses in impact resistance, weight, optical clarity, and chemical resistance.

The study, which involved impact testing and analysis of key optical and durability attributes, demonstrated that HOYA Phoenix lenses made with PPG Trivex material exhibited significantly less damage during high-impact testing compared to polycarbonate lenses. This improved performance is attributed to PPG Trivex's exceptional impact resistance, which is crucial for demanding environments such as sports and industrial eyewear [1].

In terms of weight, PPG Trivex lenses were found to be lighter than their polycarbonate counterparts, contributing to increased comfort for the wearer. Additionally, PPG Trivex lenses offered higher optical clarity due to their high Abbe value, which minimizes color distortion and ensures consistent sharpness across the lens surface. The cast-molding production process further enhances clarity by reducing birefringence, a phenomenon that can cause blurriness or distortion [1].

Chemical resistance testing revealed that PPG Trivex material remained stable under prolonged exposure to lab solvents, whereas polycarbonate lenses showed visible surface damage and whitening. These findings underscore the durability and long-lasting performance of HOYA Phoenix lenses made with PPG Trivex material, ensuring crisp, clear optics and enhanced patient satisfaction [1].

The collaboration between PPG and HOYA Vision Care reflects a commitment to innovation and evidence-based design. The latest testing results provide a scientific basis for eye care professionals to recommend HOYA Phoenix lenses made with PPG Trivex material as a high-performing alternative to polycarbonate. The study highlights the advancements in optical materials and the importance of selecting materials that optimize patient outcomes and improve lens durability [1].

In a separate development, HOYA Vision Care has introduced three innovative sun lens products—HOYA Polarized™, HOYA Polarized HEV™, and HOYA Polarized Lenses with Lumacore™ Mirrors. These lenses are designed to deliver exceptional visual experiences and are built to last, featuring advanced technologies such as embedded mirror coatings and solar blue light filtration. The introduction of these products underscores HOYA's dedication to excellence in eye care solutions [2].
