Thermoplastic is the material used in the sunglasses. Its extreme flexibility, durability and light weight make it the perfect material for performance eyewear.
As with any piece of high-performance equipment, weight is an important factor. TR90 is incredibly lightweight, which contributes to the comfort of our eyewear and the tendency to forget you’re wearing it.
POLYCARBONATE LENS MATERIAL
Polycarbonate is the extraordinarily durable thermoplastic that’s used in bullet proof glass, riot shields and astronaut helmets. It’s the ideal material for performance eyewear because of its high impact resistance, inherent UV protection and light weight. The lenses are made of polycarbonate.
The lenses block 100% of UVA, UVB and UVC rays, and harmful blue light to 400nm. These harmful rays are a leading cause of cataracts, skin cancer and wrinkles around the eyes-all great reasons to block them out.
Polarized lenses are made using an injection process that ensures they’re optically correct, decreasing eye fatigue and increasing comfort. A
