Key Properties

It is significantly lighter than polycarbonate and has a higher Abbe value (45, compared to polycarbonate's 30), meaning it has better optical clarity and less distracting color fringing (chromatic aberration).

Safety and Sports

Due to its high tensile strength and superior resistance to breakage, Trivex is one of the safest lens materials available and is frequently recommended for children, athletes, and safety glasses.

UV Protection

Trivex naturally blocks $100\%$ of harmful ultraviolet (UV) radiation without requiring additional coatings or treatment.

How does it compare to Polycarbonate?

While polycarbonate is thinner (higher index) and also impact-resistant, Trivex is superior in optical clarity (less color fringe) and lighter in weight.

What is its refractive index?

Trivex has a moderate refractive index of $1.53$. While high-index lenses ($1.67, 1.74$) are thinner, they sacrifice the superior safety and clarity of Trivex.

Is it used for prescription sunglasses?

Yes, its inherent UV protection and durability make it an excellent choice for both prescription and non-prescription sunglass lenses.
