Its extreme flexibility, durability and light weight make it the perfect material for performance eyewear. Polycarbonate lens material: Polycarbonate is the extraordinarily durable thermoplastic 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. UV protection: 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. Polarized lenses: Our Polarized lenses are made using an injection process that ensures they're optically correct, decreasing eye fatigue and increasing comfort. Polarized lenses provide protection against 100% UVA, UVB, UVC and harmful blue light to 400nm. Adjustable features: Adjustable nose pads are available in some of our design. A great feature for customizing the fit of your glasses, they are especially beneficial for those with hard-to-fit faces and anyone who needs to accommodate long eyelashes. Beyond fit, adjustable nose pads allow you to modify airflow and ventilation behind the lens by providing the ability to increase or decrease the space between the glasses and your face.
