A unique two-tone design dominates these Derek glasses. The deep rectangle shape is constructed from durable plastic for frames that'll go the distance. A dual black colourway is used for the upper rim and a semi-translucent clear shade with a subtle grey undertone decorates the lower half of the frame. A slightly dipped bridge adds understated detail. The smooth shining silver temples mix metals to provide a sharp contrast, while non-slip matt black tips fit securely behind the ears. These are the ideal comfortable companion for long days out with the family.
