Its extreme flexibility, durability and light weight make it the perfect material for performance eyewear. Ultralight: As with any piece of high-performance equipment, weight is an important factor. MOON glasses is incredibly lightweight, which contributes to the comfort of our eyewear and the tendency to forget you are wearing it. Polycarbonate lens material: Polycarbonate is the extraordinarily durable thermoplastic that used in bullet proof glass, riot shields and astronaut helmets. It’s the 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. 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. Interchangeable lenses: The technology used in our Interchangeable lenses. The different lenses, different shades and colors. This allows you to choose one that fits you best. Product maintenance: 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 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.
