The great thing about walnut is that it is one of the most flattering finishes of wood available. And with its excellent pairing with the jet black plastic frame of these glasses, you are in for a fashionable treat. In what is truly the style solution that separates the men from the boys, the assertive polaroid lenses come with polarised, anti-reflective, UV400, and mirror attributes. They also have a unique colour gradient. The glassed are square and shaped distinctly like vintage throwbacks. The lenses are 61 mm in width and 49 mm in height.
