Ray-Ban - What goes around, comes around and this is especially true with Ray-Ban Round. These round frames reflect a sprit 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. Choose the colour of flash lenses you want and no matter the look you`re going for, throwback or modern, your style will always keep coming back. Category 3. General purpose sunglasses. High protection against sunglare, good UV protection, not suitable for driving at twilight, at night or under dull light.
