The Ray-Ban Aviator Gradient sunglasses are not in drop format, which starts at all. Originally conceived for American aviators, the design of two Sol Aviator glasses turned into an icon. The gradient lenses are in interesting shaded hues, giving a bold effect to the sunglasses that will influence so many cultural movements. The RB3025 Aviator Gradient sunglasses are available in round frame and several types of lens treatments, such as blue gradient polarized glass, brown or brown gradient glass.
