Product Introduction
The Tri-Performance Standard: Resilience, Clarity, and Lightweight Comfort
Trivex represents a revolutionary leap in optical material science, originally developed for extreme durability in aerospace and military applications. As a nitrogen-based polyurethane pre-polymer, Trivex offers a unique "triple threat" of properties that traditional resins cannot match. Firstly, its impact resistance is unparalleled, meeting the highest high-velocity safety standards, making it virtually unbreakable under normal and even extreme conditions. Secondly, unlike polycarbonate—which shares its strength but often suffers from lower optical purity—Trivex boasts an impressive Abbe value of 45. This ensures minimal chromatic aberration, providing the wearer with crisp, high-contrast vision that is essential for both sports and high-precision tasks. Finally, Trivex is the lightest lens material on the market today, with a specific gravity of just 1.11 g/cm³, meaning it floats on water and significantly reduces the weight of eyewear on the bridge of the nose. Its superior tensile strength makes it the definitive choice for rimless and semi-rimless (drill-mount) frames, as the material resists cracking and flaking at stress points better than any high-index resin. For active individuals, children, and those who demand the ultimate blend of safety and optical perfection, Trivex is the uncompromising gold standard in modern lens technology.

Technological Highlights: Premium Monomers and Coating Integrity
- High-Purity Monomer Selection: We exclusively use high-performance monomers (e.g., MR-series) to achieve superior tensile strength and optical purity, resulting in excellent clarity and minimal risk of yellowing over time.
- Precision Liquid Casting Process: The lenses are produced via a controlled liquid casting method that ensures uniform material density and refractive index consistency across the entire blank, which is critical for accurate therapeutic power zones.
- Advanced Vacuum Multi-Coating (SHMC): Coatings are applied in a high-vacuum chamber, using multiple layers of metallic oxides to create a durable, anti-reflective stack. This process guarantees maximum light transmission and minimal glare.
- Thermal Curing Optimization: A slow and precise thermal curing cycle is employed to maximize the material’s resistance to internal stress, ensuring the finished lens remains stable and optically perfect under varying temperature conditions.
- Integrated Peripheral Defocus Geometry: The therapeutic design is engineered into the mold itself for cast lenses, or applied via digital surfacing for semi-finished blanks, guaranteeing the accuracy and consistency of the myopia control zone geometry.

Frequently Asked Questions (FAQ)
- Q: Is Trivex stronger than Polycarbonate?
- A: Both offer extreme impact resistance, but Trivex has superior optical clarity and chemical resistance.
- Q: Why is Trivex recommended for rimless frames?
- A: Its high tensile strength prevents the lens from cracking around the drill holes.
- Q: Does Trivex have a yellow tint?
- A: No, it is a crystal-clear material with high light transmission.
- Q: How much lighter is it than standard plastic?
- A: It is approximately 20-30% lighter than standard 1.50 index resin.
- Q: Does it block UV rays?
- A: Yes, Trivex naturally blocks 100% of UV400 radiation without extra coatings.
- Q: Can Trivex be tinted?
- A: Yes, it accepts tints well, though the process is slightly different from CR-39.
- Q: Does it come with an anti-reflective coating?
- A: Absolutely, our Trivex lenses are standard with premium SHMC.
- Q: Is it suitable for high prescriptions?
- A: With a 1.53 index, it is best for low to moderate prescriptions.
- Q: Is it resistant to chemicals?
- A: Yes, it is more resistant to household chemicals and hairsprays than polycarbonate.
- Q: Is Trivex suitable for safety goggles?
- A: Yes, it is widely used for industrial and high-velocity safety applications.
