Go back to black in these subtle, distinguished frames. These glasses are made from black metal, with a straight brow line for a businesslike aesthetic and large rectangular lenses that let in plenty of light. A thicker bridge and simple black sides add to the sleek style, with the inner temples finished in pale brown to lighten the mood and balance the look. A sturdy flexi hinge, which extends further than conventional hinges, adds a practical finishing touch to these understated frames. Pair with linen suits and sharp brogues for serious style points.
