A Swiss technology, this thermoplastic is the material used in all of our 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. All of our lenses are made of polycarbonate.
All of our 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.
Don’t use alcohol or any other chemicals to clean the lens, to avoid surface broken. And don’t maintain the sunglasses in such bad environment of high temperature or long time damp, to avoid deformation.
The lens of Robesbon Sports Sunglasses is of high technology coating, so regular cleaning maintenance by water is suggested, to make sure good quality could be kept and life time extended.
