Eyewear brand Proof has launched into the UK market for the first time with its range of frames made from sustainable materials.

The brand was founded in 2010 by three brothers from Idaho, US on the principles of heritage, sustainability and giving back.

Every pair is 100% sustainable, eco-conscious and renewable with materials such as wood, cotton-based acetate and recycled aluminium used in its eyewear.

A portion of each purchase is donated to a charitable cause, with the company supporting projects such as tsunami relief in Japan and reforestation in Haiti.
