What goes around, comes around and this is especially true with Ray-Ban Round. These round frames reflect a spirit of an earlier time but with revamped accents.Now the round lenses are flat, sitting atop gold frames, lightweight enough for any situation but still plenty strong. They may invoke another era but their construction is as modern and high quality as it gets.Design Lightweight and durable, the metal gold frame and the green classic G-15 lenses of the Ray-Ban Round Flat Sunglasses are sure to get second glances. No matter the look you`re going for, throwback or modern, your style will always keep coming back.Ray-Ban metal frames have adjustable nose pads. If sunglasses tend to slide down your nose, sit too low on your face, touch at your temples or cheeks, or feel narrow at the sides of your head, you can adjust the nose pads yourself to make the frame fit perfectly.Lens TechnologySolid colors, genuine since 1937, the classic G-15 was originally developed for military use, offers a high level of clarity, comfort and protection. By absorbing 85% of visible light and blocking out most of the blue light, green lenses provide remarkable color contrast. G-15 green lenses ensure better clarity of vision and a more "natural vision". Clarity and Protection: The lenses are shaped by diamond tools to achieve no distortion. This is done in order to achieve the greatest precision in the lens. Every single lens blocks 100% of the UVA and UVB harmful blue lights. UVA and UVB blue lights are no joking matter, so Ray-Ban worked extra hard on making sure the harmful rays do not penetrate the lens. Durability Performance Test: No lens is shatterproof or unbreakable but Ray-Ban lenses are pretty close. Impact resistance: The lenses are 2x more resistant to impacts than common lenses. The Drop Ball Test was performed on the lenses where a steel ball is dropped on the lens from a height of 1.27m. After the chemical hardening, the impact resistance of Ray-ban glass is more than doubled
